Managing Libraries on Multiple Computers

I have I-tunes libraries on two different computers that I want to manage. We may add music to each computer seperately, and I'd like to make sure that each computer is a match of the other. What is the best way to manage the music so that we can keep both computers current with the least amount of work? There are 4 ipods involved with the two computers.

If you are networked between the 2 PCs, you can have one common music library and a shared iTunes library, that way there's only one set of files (less storage used) and one library that can be updated/maintained from either PC.
To do this, I copied all of my music to a network attached storage device (a network share will do just as well) and did the same for the iTunes library (the .itl file). Then I used Tweak XP Pro and repointed the My Music folder to the network location for my music files (if you know what you're doing, and if you don't mind getting your hands dirty, you could make the same change in the registry). Then in iTunes on each PC I used the preferences to point to the shared iTunes library file.
Hey presto! I could then manage my unified 190 Gb music library from any of my 6 PCs, and could point my Prismiq Media Center at the same music folders. Now, if anyone makes a change to the library the others only need to re-open iTunes to see the changes. It would be nice if iTunes would dynamically reflect changes in the .itl file like a well-behaved networked application.
If all this sounds a bit too much then you could always use SyncToy from Microsoft to keep your two PCs music folders in sync. That's what I use to keep an online backup of my main music folders.

How to transfer videos onto iPad from multiple computers?

I have an iPad mini. Most of the time, I don't use it with a computer, but occasionally, I need to load videos onto it for editing. I have two comptuers I need to load videos from (work and home). Do I understand correctly that this is not possible? I can manage media from multiple computers via iTunes, but it appears that the only way to get videos into the camera roll is to actually sync with iTunes? And that's can only be done with one computer at a time? And that changing which computer I use wipes the iPad?
I've tried both Google Drive and Dropbox as well, and while the videos do show up and are playable, there doesn't appear to be any way to get the videos out of either app. The videos are in MP4 format.
Any advice?

One work around could be: say you sync with comptuer A, use dropbox to get the videos from B to A, then iTunes to get them from A to your iPad.

Managing content on multiple machines?

Although some of the question maybe have been already answered by other posts, I'm looking for the definitive answer.
As a proud new owner of a iphone 4, I've downloaded many applications using the phone over wi-fi from the App Store. I've also synced my iphone at home with Music etc. Thinking it would be a good idea, I also have itunes installed on my office PC and recently purchased an application.
Now how do I get the app i purchased from my work PC to my phone without wiping all my (paid) apps?
I'm also interested in synchronizing my outlook contacts, calendars with my work PC without wiping the device, is this possible?
Finally: For the applications that are downloaded via the app store on my iphone, what happens to them? Will they get wiped, how would I get them back again? Is it possible we manage applications on multiple computers?
Thanks for your time and reading this post

It can be done. It is not pretty, and it is not easy. You have to move your entire iTunes folder from the master computer to the secondary computer at the beginning, and you have to have a way to keep them in sync, other than taking your phone from one to the other. Since you are supposed to have an offline backup as well, you could use it to carry any changes from one computer to the other.
I sync my iPhone both at home and at work, and do this. Make sure you always move new content into the iTunes folder, otherwise you will forget to copy it at a later time.
As for content bought on the iPhone, while connected to iTunes, right click on the phone name listed on the left, and select Transfer Purchases.

Will the new iCloud feature sync Aperture libraries between different computers?

If there was a Cloud section in the forums i would post this there but there isn't so here it is. Syncing my Aperture libraries between my laptop and imac is a big problem for me right now. Does anyone know if the new Cloud air synching feature coming this fall will sync photos between aperture libraries on multiple computers?

There is now an iCloud community iCloud
But I believe the answer to this question is no, iCloud is not meant to do this type of syncing.

Best way to manage photos, multiple computers, multiple input mediums

I have a multitude of questions regarding photo library. I have a bit of a mess on my hands.
i have 30K photos on one computer at home (24'imac) and my husband and I both have laptops (macbook pro). I have his "hand me downs". When we switched to the 24"imac (from the small imac), I noticed later (I was not here at home for several months) that it seemed that pictures from my canon library from several years ago seemed to be missing. The person who did the changeover (of course) pleaded ignorance and I believe didn't do a proper backup. In fact I have noticed pictures on my husband's or my laptop, I don't see on our "now" primary machine. I reloaded any CD's i had, however, now i have multitude of picture copies as the "CD created" copy now has another name with a completely different date and year! Further, my husband would take his computer with him on vacation and download photos and sometimes i am not sure all the photos made it to the main computer! So i have these separate libraries on separate computers!
One of my projects in the upcoming year is to consolidate all these libraries so I ensure i have one final version and then set out to reduce, edit these photos, make slide shows, etc with them instead of holding all or most photos on each! It was a learning experience for me as i recently made my first book and found out that i used only 30% of the photos (of 1500 photos) so i think i really need to do a much better editing job to effectively reduce the number of photos. I would also like to even scan my current paper photos, slides, negatives into this, hence creating a large library, slide show, books, etc. In fact I would like to eliminate most of my photo albums!
My thought is that i need to
1) consolidate all libraries from all computers into one library on one hard disk
2) divide libraries by year
3) OBVIOUSLY---backup the library(s)
4) reload or keep on the 1TB hard drive all the photos
5) create an additional backup
I hope this makes sense. I am just not sure how to go about it. Given all I have read about error messages and libraries gone missing, I am concerned about the process I use to do this. Thanks!

The best way is create one Library from several is to use iPhoto Library Manager and its' merge command.
Why do you want to have multiple Libraries? iPhoto is good for 250,000 in a Library.
However, if you do want toL Managing Multiple Libraries - including moving pics/albums/rolls and metadata between them - is greatly facilitated by using iPhoto Library Manager
As for scanning? WHat software comes with your Scanner? I have had perfectly acceptable results with Image Capture.
I am concerned given all that i have read about "missing" iphoto libraries and errors.
I'm not sure what you mean by this, but it is important to have a back up as protection against problems.

Manually managing music on iPhone from multiple computers

Everything I've read 'claims' this can be but I don't think the people who tell you how to do it even bother to see what happens. This is one of the things that really frustrate me about forums. It's the complete lack of thoroughness of the people who reply to a question without knowing the outcome.
It's a simple task. I want to be able to move music from multitple computers to my iPhone. When I go into iTunes and select the device, in my case it's the iPhone, and check the box to manually manage music and videos then click 'apply' I get a warning that everything is going to be erased from the phone. WTH!?! And no one on ANY forum who suggests this is the proper way manually managing music even has a solution to be able to do this WITHOUT erasing the phone.
C'mon Apple. It's a SIMPLE drag-n-drop implementation. How hard can it be? I'm not the least interested in syncing with some music library on the computer. In fact I don't even sync my phone with the iTunes Library. It's a waste of time because I can't even selectively sync music. It's either all or nothing. STUPID. I simply want to move music on and off the phone. You know, drag into the window to add and drag off to remove. And I want to be able to do it from any computer I want that's running iTunes. I shouldn't have to copy music from a different computer, carry it home and add it from the home system. That completely defeats the concept of portability. And if my home computer happens to go south for some reason then what? Even if I have all my music backed up, I have to wipe out all my music on the phone and start all over because I'm now using a different computer. Who was the genius that came up with that ludicrous idea?
Apple you really need to take a page from Sandisk and allow iPhones to be treated as external drives so we can drag and drop our music onto them. No muss no fuss. Simple and clean with no hair pulling. It's already established the you create some very pretty devices. Now let's work on improving usability. Because the way I see it, it's a bit backwards.

Sync iPod/iPad/iPhone with two computers
Although it isn't possible to sync an Apple device with two different libraries it is possible to sync with the same logical library from multiple computers. Each library has an internal ID and when iTunes connects to your iPod/iPad/iPhone it compares the local ID with the one the device normally syncs with. If they are the same you can go ahead and sync...
I have my library cloned to a small 1Tb USB drive which I can take between home & work. At either location I use SyncToy 2.1 to update the local copy with the external drive. Mac users should be able to find similar tools. I can open either of the local libraries or the one on the external drive and update the media content of my iPhone. The slight exception is Photos which normally connects to a specific folder on a specific machine, although that can easily be remapped to the current library if you create a "Photos" folder inside the iTunes Media folder so that syncing the iTunes folders keeps this up to date as well. I periodically sweep my library for new files & orphans with iTunes Folder Watch just in case I make changes at one location but then overwrite the library with a newer copy from the other. Again Mac users should be able to find similar tools.
As long as your media is organised within an iTunes Music or Tunes Media folder, in turn held inside the main iTunes folder that has your library files (whether or not you let iTunes keep the media folder organised) each library can access items at the same relative path from the library folder so the library can be at different drives/paths on different machines. This solution ensures I always have adequate backups of my library and I can update my devices whenever I can connect to the same build of iTunes.
When working with an iPhone earlier builds of iTunes would remove any file not physically present in the local library, even if there was an entry for it, making manual management practically redundant on the iPhone. This behaviour has been changed but it will still only permit manual management with a library that has the correct internal ID. If you don't want to sync your library between machines on a regular basis just copy the iTunes Library.itl file from the current "home" machine to any other you want to use, then clean out the library entires and import the local content you have on that box.

Music and Video on Nas in folders but how do i set up itunes on multiple computers to see and use these files and create libraries?

Music and Video on Nas in folders but how do i set up itunes on multiple computers to see and use these files and create libraries?
So i have had a itunes set up on my old PC, bought a NAS and copied the folders over to the NAS, i did this incorrectly and so then even when i told the old PC to use that folder it saw all the songs but wasnt able to play the songs as it was looking in the incorrect place.
So now i want my Mac as well as my PC and others to all use the music, videos etc on the NAS they are in itunes friendly folders (as they were compiled this way by the itunes on the old PC.
When i tell the mac to use the itunes library.itl file it sees the song list (about 100gb) but cant see any songs, so i have removed this file to another location for now with the hope to set up a new file and then get it to see the songs on the folder from the NAS.
Can someone tell me how to do this for all the Mac's and PC's on my network as i really want one master library that all use and add too.
Thanks for your help in advance.

I have the same question but I am using two pc's

How to use iPhone with multiple computers on iTunes 11?

Both of my computers are Windows 7. I try to manage my music and videos on both iTunes. I used to be easy, like you just check the "Manually manage music and videos" square, and everything is fine... But after I update to iTunes 11, it just doesn't work. There is no resulting dialog box coming up where I can click "OK" after I checked square, and no matter I click "apply" below or "done" above, the iTunes asks to erase and sync with the iPhone. After it syncs, the "Manually manage music and videos" is checked. But if I move to another computer another iTunes, then it says I'm already syncing with one iTunes, and it needs to erase and sync with my iPhone again... and of course, the "Manually manage music and videos" is unchecked on this iTunes... If I try to check that on this one.. it's the same story happened before... Basically, there is just no way I can use one iPhone on two iTunes 11, is it?

Multiple family mbrs, multiple ipods, multiple accnts, multiple computers

I have a family of 6, we each have various ipods (iphone, ipod, nano, shuffle, etc), and we have multiple computers -- some Mac and some PC.
We need to understand what factors impact the ability to put a particular track on one or more devices, manage a given device from one or more accounts on one or more computers, and share, as allowed, between devices, people, iTunes libraries, iTunes store accounts, for both purchaed tracks and MP3 files that we might already own, etc...
I'm looking for a simple and concise description of all of the factors. Any pointers?
If the iTunes world were simple we could simply each have our own music -- stored in one or more places in one or more accounts, on one or more computers. We would be able to share what we like, and put whatever subset we like on whichever device, manage any device from any account on any computer, etc... Of course this could be subject to licenses, but it should at least be possible to get a statement of what license restrictions exist.
Can anyone suggest any references for this? I assumed it was simple, but anyone who has recently plugged a "guest" iPod into another computer will know this is not the case after having been rewarded with the choice of wiping all content off of the iPod, or somehow transferring the content to the friend / family member (with no clear indication of whether this also comprises transferring the content away from the original user, nor how, if possible, to undo such a move later, etc...)
I have seen an article relating to using multiple ipods with one computer, but it does not address all of the issues -- for example using one ipod with multiple computers, etc...
Thanks in advance.

Let's see if we summarise the main points that will help you decide on a strategy:
+ An iPod can automatically sync (one-way transfer from iTunes to iPod) with just one iTunes library.
+ An iPod (but not an iPhone) in manual mode can accept tracks from multiple libraries.
+ iTunes can transfer (copy) purchases from an iPod into the library if authorised for the account used to purchase them.
+ Networks, memory sticks, portable hard drives, CD-R, DVD-D and iPod to PC transfer programs can be used to move other content between your libraries.
+ The new "home sharing" feature probably has some relevance too, but I've not explored just what the capabilities are.
+ For each account, DRM puchases can be authorised on up to 5 computers at any one time.
+ For each computer, up to 5 accounts may be authorised on it at any one time.
+ Each iPod may hold DRM content from up to 5 different accounts.
+ DRM content may be transfered to as many iPod's as you wish.
+ Most iTunes Store content is no longer subject to DRM, the main exceptions being Movies & Games/Applications.
+ iPods can be formated for use with either Mac or Windows. You can manage content on a Windows formatted iPod with either system, but the reverse is not the case. Firmware updates & restores must take place on the native system.
+ An undocumented/unsupported feature is that if you clone a library (make a complete copy of the iTunes library files and media content) and place this on another machine, an iPod "synced" to the original library will also see any clone as its "home" library. Once cloned you don't have to keep all the content available in each locataion. For regular iPods if syncable content cannot be found corresponding files on the device will be left alone (not updated or deleted).
+ The main database file of an iTunes library can only be opened by one process - multiple users on the same computer or over a network will lead to problems. Always close iTunes before switching profiles.
+ The media content folders can be simultaneously accessed by multiple accounts.
+ Automatic syncing has a number of advantages. You can update tag info. in iTunes knowing that when updated the iPod will recieve all the updates. Using playlists you can manage the content that will go on an iPod without having it connected. Ratings & playcounts can sync in both directions. All the content required to restore your iPod is in one location.
+ Manual management allows you to add content from whichever library you are connected to.
+ iTunes does not keep track of files moved or updated by other programs or instances of iTunes. If you share content folders then it is best to avoid the *Keep iTunes Media folder organised* option. When you update content on one machine, e.g. change a capitalisation or correct a spelling, other libraries will only notice the change if they access the file in some way, e.g. by playing it.
I'm sure there's more that I can't think of just now but that's a start.
*Personal Case history:*
Our family has an iPhone, a Nano, 3 Classics (old & new) and a 5th gen. I started by making most of the purchases on my account, putting the children's gift cards onto my store account for example, but two now have their own accounts. I manage most of the music in one main library that sits on a network. One child has a separate library which started as clone of the original and then had content that he dislikes removed... This means I can update his iPod at either his machine or mine although if I add any of his music I have to remember to update both libraries. When he uses iTunes on his computer he only sees the rock/blues/metal that he likes whereas the main library has everybodys content lumped together.
All the iPods are set to sync automatically using the method two (Sync with selected playlists) from the Apple support document How to use multiple iPods with one computer, although I have a slight twist. Rather than regular playlists I set the grouping field to indicate which users should receive which tracks and create smart playlists based on the content of this field.
e.g.
"Alice's Tracks" is "Playlist is Music" + "Grouping contains Alice" + "Kind contains audio"
"Bob's Videos" is "Playlist is Music" + "Grouping contains Bob" + "Kind does not contain audio"
Tracks that both Alice & Bob want on their iPods have the grouping set to "Alice/Bob"
etc.
This way each of us gets a different selection of content to suit our tastes and the capacity of our iPods. An advantage of using the grouping field is that it is stored in file tags (for non-wav audio files anyway) so that it is relatively easy to recreate the playlists should the iTunes library get trashed. Also useful if you move files about manually as playlist membership is preserved when you delete & re-import the tracks.
However you choose to do things you should also create a backup. My main library gets synced to a portable hard drive using SyncToy 2.1 (Windows) which I sometimes take to work and sync there, giving me three complete copies of my library at any one time and I can update any iPod from any instance of the library. An occasional scan of the contnet folders with iTunes Folder Watch helps me catch up if, for example, a podcast has download at one location but the library is overwritten with a newer version from the other.
Hope that's given you some useful food for thought...

Synching/manual add to multiple iDevices with multiple computers.

Okay, Here's the issue.
I own an Iphone, and multiple versions of iPods (3 different Nano versions and an old Ipod Photo).
I also own three PC's. One desktop, one laptop and one netbook. All run windows 7.
Why is it that it is so bloody impossible to share the three different libraries with the different equipment?
I have a laptop at my girlfriends, my desktop at home and my netbook for when i travel. Ideally I should be able to plug any of the devices that i own and have registered to my apple ID into any PC that is an authorised PC on my account and just drag and drop whatever i want.
Unfortunately this is not the case.
I always enable manually manage music upon first registering a device, as i dont particularly like the whole synch option. I'd just ratherdrag and drop albums as i fancy them, so why can this option not just be tied to each device ID within my apple account, thus when i use one of my authorised machines the setting will be valid and hey presto i can take media and put it on to any of my devices. Is this so difficult?
I also have a WP7 phone, and it seems microsoft can manage this without any problems!
What happened to "Apple, it just works"?
Obviously not in this case.
After quite a bit of googling this is also not an isolated incident as people have been complaining about this since iTunes 7! (this was the earliest mention i could find)
Apologies if this sounds like a rant, its something that has irritated me since i got my iPod photo in 2003!
I am also aware of the editing the itunes music library xml file and replacing the persistent ID workaround, but this is a real pain to play about with.

Can I setup common iPhoto library for multiple computers...

Hi -
Is it possible to have one library that is accessible from multiple computers in different locations? For example, my office Mac, my home Powerbook and our vacation home iMAC can all share the same photo library? I am downloading pictures from many different sources and in different locations and would like a centralized library.. I guess this would be the equivalent of cloud computing for iPhoto...
Thanks,
M.

Possibly. I've not used the feature but if you have a MMe account you could setup "Back to my Mac" so that two of your Macs could access the Mac designated to house the library you might be able to do what you want. It would be best to have an external FW hard drive connected to that library to house the library.
I've used an iPhoto library on my iMac from my laptop on our home WAN. But that was with Screen Sharing. Don't know if the Back to My Mac method would work.
I've used VNC to connect to my iMac from the laptop but don't know if that will let me add photos to the library there as that method has me virtually on the iMac. You could try it with a test library and one of the VNC applications. I use Chicken of VNC. You must setup Remote Management under Sharing on the host computer and install CVNC on the remote Macs. Create a test library and give it a try. Both with VNC and Back to My Mac if you have it.
If any of the two satellite Macs would be wirelessly connected that will be a problem due to occasional dropouts. If a wireless Mac was using the library and had a dropout that could damage the library's database and require some rebuilding effort which may or may not be 100% effective. That connection would also be slow.
If they are hard wired to the internet it would be much more probable that it would work as you'd like and be more reliable.
An alternative method for "syncing" the libraries (if you have a MMe account) would be to create iPhoto MMe galleries of new photos from each Mac with the option for downloading the full sized image file. Once each Mac has downloaded and imported the new photos the gallery could be deleted.

Multiple computers can't be used?

My music is spread between 3 different laptops, and every time I try to get music from one of the three, I have to sync it, because the 'manually manage music' box is not checked. How can I get my music from all 3 comps without having to sync to one?

The deal is this: Using iPad or iPod with multiple computers, http://support.apple.com/kb/HT1202 "iPod shuffle and iPhone are intended for use with a single computer. You cannot load music from multiple computers or iTunes libraries onto iPod shuffle and iPhone like you can with other devices."

Different iTunes libraries on two computers question

Problem: I bought the new iPod, with video cap.
I do have a G5 desktop computer with a music library. Last week I travelled to the States and bought some music in the iTunes store. That music downloaded on my laptop.
The music from my laptop is currently on the ipod.
Is there a way to add the music from my desk top computer to the ipod without erasing the music already on it.
I find it a bit disgusting that it is such a pain to not be able to just drag and drop between ipod libraries and computer ones...
In short: I want all my music from two computers on the ipod... What is th ebest way to go?

When the iPod is connected to your PowerBook, set it to manage music manually. When this is done, you can copy music from multiple computers onto the iPod without losing anything previously put onto it.

Syncing to multiple computers

when syncing my ipod touch to my computer at work, it deletes everything stored from my home computer. what am i doing wrong?

If you want to connect and use an iPod on more than one computer you need to change the update preference in the iPod Summary tab to "Manually manage music and videos" and click Apply. In this mode you can directly access the content of the iPod and play it through iTunes and you can drag and drop whatever you want to the iPod from either library:

How to sync with multiple computers?

I have my iTunes library on my MacBook and all of my Apple devices synced accordingly. My family also has an iMac, and I would like other family members to be able to sync from the iMac. I know I can use Home Sharing to allow the iMac to view/play the music when my Macbook is active on the network. I also know I can purchase iTunes Match so I can access the music when my MacBook is offline and edit the playlists. Yet, I would love to be able to set up the iMac so the iDevices could actually by synced with that computer as opposed to mine. How can I go about this?

Yes, you can sync your device with multiple computers. Only that one is set to AUTO SYNC whilst the rest is set to "MANUALLY MANAGE MUSIC".
Refer to this article:
Using iPhone, iPad, or iPod with multiple computers
http://support.apple.com/kb/HT1202
However, issues may occur leading to data corruption or data loss if you regularly sync Contacts, Calendars, Notes, or bookmarks between multiple computers using iTunes and your iOS device. Syncing once to move your data to a new computer should not cause these issues.
