How do I place the Lightroom Library on an External Drive?

Q: How do I change the location of the Lightroom Library on an external disk drive whilst also ensuring that lightroom maintains the connection with the new location?
A: The easiest way is to copy the folder containing the Lightroom Catalog and the Previews to the new disk drive, navigate to the new folder location, then double click on the Catalog file to relaunch.
Note: the Lightroom catalog and preview package use the
lrcat and
lrdata extension respectively.

1. Drag the library to the external drive, launch iTunes with the Option key held down, click on Choose Library, and point it there.
2. Get a second. Having the backups on the same drive as the original data won't help when that drive fails.

    On imac 10.6.8 using current version of Aperture.  How can I access the Aperture Library  on my external hard drive that I use with time machine for backup?  I can only access the application but not the library..

    Go into Time Machine (the program not the bundle on the extrnal disk) and using Time Machine's browser go to the Folder where the library lives. You could look in the library bundle in Time Machine but that won't really tell you much,
    If you want to make sure it truely has backed up your library you will need to restore it and open the restored library with Aperture.
    If all this still has you confused you need to read up on Time Machine in order to get a feel for how it works, for what it is doing and for how to restore files from it.

  • Imovie 10: how to move the (movie) library to an external drive

    Hi all,
    using imovie '11 it wasn't any problem to move the (movie) library to an external drive following these instrcutions: <http://support.apple.com/kb/PH2289?viewlocale=en_US>. After updating to mavericks and imovie 10 I can't find the hard drive icon to pull down the drive list any more.
    Maybe I missed something very obvious but would be very happy for any suggestion.
    Thanks in advance,
    best regards,
    Stephan

    Your events and projects now reside in an file or files  with extension .imovielibrary.    You can create a new library wherever you want from within iMovie and drag and drop events into it from an exisitng library.  If you want to move the complete library, select the library then go File - Consolidate Project Media.  This ensures the library is self-contained and doesn't have any links to external media which could break when it is moved.  You can then move the library to the external HD using the Finder.  When you restart iMovie you will have to select  File - Open Library - Other and navigate to its new location.
    There are a lot of changes in imovie 10 and its really necessary to study the help file (http://help.apple.com/imovie/mac/10.0/#mov3fa25bae7)

  • HT1373 How do I backup my itunes library to an external drive

    My iTunes library is unstable.  I have two questions:
    1) How do I backup my iTunes library to an external drive?
    2) Why am I constatntly prompted to add my computer to iCloud when I have done so multiple times?
    When opening iTunes, I receive he error message: "Please Sign In Again,  iTunes Match has encountered an error.  Please choose Sign Out and he Sign In from the iTunes Store menu and try again."
    I tried downloading and installing/repairing the latest iTunes.  That did not correct the problem.
    Also, I have sync'd to iCloud.  Every time I select iMatch from iTunes, I am prompted to Add This Computer to iCloud.  I have already done this multiple times.

    Hello cijackson,
    You posted your question in the iTunes for Mac Forum. You may get better results on the iTunes for Windows forum. Best of luck > https://discussions.apple.com/community/itunes/itunes_for_windows?view=overview

  • Sorry folks, I did something bad, I was looking how to save my current iphoto library to my external drive and I hit a wrong button, lost my current iphoto and now have only the backed up version from 2007, Woops I never was the quick witted one... PLEASE

    I switched my current iphoto library out for the saved one on my external drive by mistake. It said, Switch Libraries.... Do you want to switch the current iphoto library from AAA iphoto library (what I called the old one I guess - in my OWC) toOWC Mercury on-the-go and relaunch iphoto? cancel or relaunch
    Sorry, I was looking for a way to save my current iphoto images to my hard drive. Yeah, I guess just drag something over right? Anyway, now I cannot retrieve my last 2 or 3 years of photos, Can You HELP me?

    Depress the option key and launch iPhoto = use teh select library option and select the correct one
    yes to move your library to an external drive
    Moving the iPhoto library is safe and simple - quit iPhoto and drag the iPhoto library intact as a single entity to the external drive - depress the option key and launch iPhoto using the "select library" option to point to the new location on the external drive - fully test it and then trash the old library on the internal drive (test one more time prior to emptying the trash)
    And be sure that the External drive is formatted Mac OS extended (journaled) (iPhoto does not work with drives with other formats) and that it is always available prior to launching iPhoto
    And backup soon and often - having your iPhoto library on an external drive is not a backup and if you are using Time Machine you need to check and be sure that TM is backing up your external drive

  • How do I move an iTunes library from one external drive to another?

    I need to move my iTunes library from one external disk to another, because the original disk is about to fail. So, I went into iTunes Perferences --> Advanced, and set the library to a new, empty folder on the new drive.
    Nothing changed. I expected all my music to vanish from iTunes, so that I would have to re-import it. However, all the music remained, still on the old disk. At this point, if I were to recreate the library on the new disk, I would have all of my music twice.
    Is it possible to move an iTunes library from one external drive to another, or am I stuck with my original choice until I buy a new machine? If I can move it, can one of you clever folks explain how it could be done?

    However, those are all dealing with old versions of iTunes that still contained the Advanced --> Consolidate Library command which is no longer part of the app. (I'm on iTunes 10.6.1.)
    Consolidate is still part of iTunes.
    It is in iTunes menu File > Library > Manage library > Consolidate.
    The article you linked to is old and it is (and was) a hacky way of doing it.
    Just copy the entire /Music/iTunes/ folder to new location, hold Option (Mac) or Shift (Windows) when launching iTunes.

  • How do i manage 1 iphoto library on 2 external drives?

    I'm trying to find the most efficient way to manage 1 iphoto library across 2 external drives. In case one of my external drives dies, I'll have a backup.
    I know how to copy my iphoto library onto another drive, but my question is how to manage the 2 drives when i add photos/videos to them from my iphone.
    Currently, I import photos/vids from iphone onto 1 drive. Then unmount the external drive and hook up another drive. I direct iphoto to use the new drive as it's library and then import the photos/vids again onto the second drive. I make sure the event is named the same, so I have the same iphoto setup across both drives. Then i delete the photos/vids from my iphone.
    Is there a more efficient way to do this? Or software that can do this in one step?
    Thanks in advance for any help! 

    You want to have a backup of your working library on your MacBook Pro on each of two external HDs, correct? 
    If yes then use a backup application like Synk or Synk Pro that can incrementally backup the library, i.e. copy only those new of modified files.  If you go to MacUpdate.com and do a search for "backup" you'll get a list of potential candidates.
    Then all you need to do is connect EHD#1 and run the backup app to update the library then connect EHD#2 and do the same.  It only takes several seconds to make the incremental backup.  Synk Pro can be configured to automically start the backup when the external drives are connected.  I'm not sure but believe some of the other backup apps could do the same.

  • How can I transfer my iPhoto library safely to external drive?

  • How do I move my itunes library to an external drive to free up space on a Macbook?

    Hi, I'd like to free up some room on my Macbook and was thinking of moving all my music library to an external drive. I hardly ever use my computer to play music, more I download an album and then sync it to my iphone to play from that. I use itunes and back up with time machine, but would like the music folder separate entirely, is this possible?
    Thanks in advance.

    Drag it from the Music item of the Finder's sidebar to an external drive, launch iTunes with the Option key held down, and point it there.

  • Moving the iTunes library to an external drive

    I followed the Apple article and successfully moved my iTunes library to an external drive. BUT, is the Album Artwork supposed to stay in the original location (internal drive)? Mine did, and I had to redownload album artwork again. HOWEVER, I don't have all my artwork since the transfer and since the redownloading of it.
    Is it safe to drag the album artwork folder to the external? I don't want to mess anything up.
    Thanks.

    I followed the Apple article and successfully moved my iTunes library to an external drive.
    which article (post a link) did you follow and what exactly did you move to the external ?

  • Can I optimize the iTunes library on my external drive?

    I have my iTunes library on my external drive, which by the way, is very full (only 40 of the 500 gb free). It takes ages for ITunes to start up, and I believe it's because of the very full harddrive. Is this really the case, though? And is there a way to seppd up opening iTunes?
    André

    I don't think a G5 is that old. Maybe running Leopard would change things, but I have to save for that...
    Still, it started to take longer after I had put all my files from the main drive on the external one so i think it's because that drive is almost full. Is there a program to optimize an external drive, I remember you have the for the pc, reformat or something like that.

  • How do I import an iTunes library from an external drive if that drive has been simply removed from a dead computer, without prior measures being taken to ensure it is possible to transfer the library over?

    Basically, my issue here is, I had a fully functioning iTunes on my previous Acer laptop which I used to store my music for my iPhone, I have over 2000 songs on this iTunes and as the laptop suddenly died due to motherboard failure, there was no way to follow out the instructions given by apple on how to properly transfer one iTunes library to another.
    The only source of music I have comes from source files on the HDD, which, stupidly I chose to organise myself.
    A large quantity of this music was deleted from the iTunes library but stayed on the HDD in the source folders (I do not know why)
    By simply dragging my music folder from my HDD to a new iTunes, all the files do go over, however many of them are duplicated (due to 320>120 bit rate MP3 creations) and a number of them are simply not wanted.
    Is there a way to transfer my old library straight into this new one? bearing in mind I have all the program files and everything that had iTunes running on my old computer stored onto this USB drive?
    Thank you!

    When I have done this, all I did was network the two machines and copy the contents of the iTunes folder to the other machine, and that's it.
    My understanding (which may not be 100% correct) is that the one file that is absolutely necessary is iTunes Library, and that the XML file is actually a copy auto-generated from the iTunes Library, appearing in a different format only for non-iTunes apps that take advantage of the iTunes Library data.
    As far as I know, if you simply have the Library (database) file and all your original music files, iTunes on that computer should operate as it did on your old computer. I believe that the Album Artwork, Genius Data, and XML files can be regenerated from the Library file. Not sure about the Extras file.

  • How do I store my iTunes library on an external drive and can I still access it as I would if it was still all sitting on the mini mac?

    The mini mac is full and I want to be able to use the 2 tb drive as storage and time machine. How do I get the content onto the external drive and access it it and hoe does new content get downloaded and stored to the drive not the mac? Also can I have 1 drive playing storeage and back up or do I need a second? Basic questions I suspect but not to me!

    1. Drag the library to the external drive, launch iTunes with the Option key held down, click on Choose Library, and point it there.
    2. Get a second. Having the backups on the same drive as the original data won't help when that drive fails.

  • How do I move the Photostream library to a secondary drive?

    I have a small (44GB) SSD as my boot drive in my Macbook Pro (4,1) and a 1TB secondary drive in lieu of the optical drive.
    I already have my Mail folders/library reside on the secondary drive.
    Is there a way to do the same with the Photostream library?
    I use Aperture, and obviously reference the photos which are stored on the secondary drive as well. I would like to be able to to reference Photostream in the same way.
    Thank you.

    It's an Aperture library that I have referenced.
    However, since I posted this question I've actually done the following which seems to have accomplished what I was hoping to do.
    1. I have my Aperture library itself residing on my secondary drive.
    2. Using Daisy Disk, I managed to find that the Photostream photos are stored in the iLife Assests folder in the Library.
    a. I moved that folder to my secondary drive.
    b. Used Symbolic Linker to create a symbolic link of that folder and copy back to its original position/folder.
    All this seems to have had the desired effect as I can see that as Photostream syncs into Aperture, the secondary drive is filling up.
    .ends.
