HT1449 Partially corrupted iTunes library after moving media folder

I moved my media folder to a new hard drive but somehow lost the library file in the process. I used my time machine backup to get an old library file and I placed it back in the iTunes folder on my home drive, but unfortunately it's a few months old, and additions to my itunes folder since then are invisible when I open iTunes. Is there a way to force the iTunes app to rebuild the library, thus recognizing my new downloads since the old library file was built? Songs I'd downloaded and copied from my CDs up to the old library build are working fine.

You probably should have done:
iTunes: How to move [or copy] your music to a new computer [or another drive] - http://support.apple.com/kb/HT4527
Quick answer if you use iTunes' default preferences settings: Copy the entire iTunes folder (and in doing so all its subfolders and files) intact to the other drive. Open iTunes and immediately hold down the Option (alt) key (shift on Windows), then guide it to the new location of the library.
To answer your question, drag the media folder on the other drive to the Automatically Add To iTunes folder. It will add anything that's not in iTunes and ignore anything that is.

Missing iTunes library after moving computer

I recently moved my iMac to a new home, and my iTunes library has disappeared. I have checked all of the usual places and apparently no media exists in my iTunes folder. It's also not showing up on my external hard drive. Any idea what might have caused this? And how to get it back?

I have this problem too. I can find all music I purchased on iTunes on the cloud.. but thousands of other songs are not in library. I do have them backed up in a mavericks back up, but if i could get them back in yosemite that would be ideal.

After an update, my itunes library was moved to my music file. I tried moving the file (itunes library.itl) into itunes, it said that the file was locked. How can I get the file to be unlocked so it can be moved?

I deleted my itunes library (after backing up) now i want to restore from TM to my MBA but its saying there is not enough room even though the library is 22GB and there is 27GB free on my MBA??

Hi everyone,
I deleted my itunes library (after backing up to my time machine) to download a large torrent, now i want to restore my itunes library to my MBA from time machine but its saying there is not enough room on my MBA even though the library is 22GB and there is 27GB free on my MBA??

Here's something else to consider:
Since Snow Leopard, OS X uses a Decimal count for file size. iTunes however still uses a Binary count. What that means is: your iTunes library shows one size, while the folder shows another. Depending on the size of your library, this can be a pretty big difference.
Yours won't be that much, but it may be enough to prevent it from moving to the MBA from the TM.

All of a sudden (video) files added to my iTunes library after a certain date aren't playable on other devices.

hello!
All of a sudden I have a weird issue with playing video-files added to my iTunes library after a specific date.
This is the situation so far:
I encode the video for iTunes with the same settings for the last 3 years. I know these vids play on all my devices. AppleTV & iPad. All of a sudden videos added to my library after the 8th of september aren't playable on my AppleTV and iPad. I can play them directly in iTunes and by accessing them directly via the finder and quicktime.
The following errors occur:
When I pull the video from iTunes on my AppleTV.. the video simply doesn't play.
When I pull the video from iTunes on my iPad I get a message that the file can't be found.
When I push the video from iTunes to the AppleTV using airplay I get a message that there has occured an error while connecting to the AirPlay-device "Apple TV". The necesary file could not be found. In addition when the AppleTV is switched off it doesn't turn on doing this, suggesting that there is something missing on my mac itself.
All the above errors aren't popping up when I choose a video that has been put in my library before the 9th of september. Then everything works as expected.
This is what I tried:
Turning off and on home sharing on all devices including the mac.
Logging in wiht a different apple ID though using the same ID as before.
I created a new iTunes library and populated with a video that was added after the 8th of september and one that was added before the 9th of september. Surprisingly the older one played and not the newer one.. while they both used the same encoding settings. The new library was locally on my mac as my original library is on a NAS.
I encode my videos with Quicktime 7 Pro using the following settings:
H.264 (current frame rate, key-frames:automatic, re-order frames, automatic bitsize)
Medium Quality
Multi-pass
current resolution (which is always 1280 X 720)
AAC sound
44.100 kHz
128kbps
I'm using the Mountain lion 10.8.2 and iTunes 10.7 Mountain lion got updated a few days after 19th of september and iTunes i think as well. Both versions were released after this issue seemed to pop up.
I also have two video-files encoded on the same day with the same settings that dragged into the iTunes library on the 9th of september. One works.. the other doesn't.
So I wonder if there is somebody out there that can tell me what might have happened here and how I could fix this issue.
Thank you in advance.

Hi Seraphiel07.
I have a very similar issue. Hardware involved:
Apple MacMini (Mid 2011) - OSX 10.8.2. iTunes 10.7. Home Sharing enabled.
Apple TV (3rd Generation). Home Sharing (access) enabled.
Apple MacBook Pro (15" Mid-2009). OSX 10.8.2. iTunes 10.7. Home Sharing enabled.
Apple iPad 2 (Wifi only). iOS 6
Apple iPhone 4S. iOS 6
All connected through:
Apple Time Capsule 8.0211n (4th Gen)
I have an iTunes library on the MacBook Pro, shared over "Home Sharing" and another (duplicate content, different library name) iTunes library on my MacMini, which is also accessed through the Apple TV.
All software is current (as of Sep 26th).
All movies are iTunes purchases. 80 in total.
All files are purchased (and home shared) under one account.
My last two iTunes purchases both HD movies on 09/17/2012 and 09/05/2012 refuse to appear on any device accessing either of the two Libraries over Home Sharing. It should be noted that every other movie (the other 78) all show up and play correctly. I therefore know it is not an issue with connectivity, otherwise I would see zero movies available.
I have:
1. Removed all content from each Library and re-added
2. Upgraded the OS on the MacMini 10.8.2
3. Tested viewing the two missing movies on other Apple devices and no luck.
4. Turn home sharing on and off within iTunes and also on each device.
It would appear to me that the issue is with the files themselves, rather than the devices as different devices and different versions have been tested.
All comments welcome.

None of my iDevices can read my iTunes library after an hour of availibility. When I first start iTunes I can read the library, but after about 30 minutes my iPad's and iPhones can no longer access the library. I see it in the shared list, but no access.

None of my iDevices can read my iTunes library after about 30 minutes. My iDevices lose connection to my library and I have to do one of the three following things in iTunes to regain connectivity: 1. Restart iTunes 2: Stop / Start Home Services 3: Start playing a song.
I'ts as if iTunes goes into a background or sleep mode. During the loss of connectivity my iDevices show that there's a library shared, but I cannot connect to it.

Smae issue here, but I'm unable to get Home Sharing started again (after MAc and iOS restarts, Home Sharing on/off. etc.) This happend a few weeks ago and turngin Home Sharing Off/On fixed the connection issue b/w iPad2 5.1 and iTunes 10.6.1 running on a OSX10.6.8.
I updated to iOS 5.1.1 on iPad2 today, watched a movie and then about 20 minutes into a 2nd movie I lost connection (Sharing tab in Video app disappeared and has not come back.) The update seems like the culprit, but odd it worked for over 2 hours before stopping, odd I can't get Sharing to work anymore (iTunes see's my iOS devices b/c I can conenct to iTunes to enter my passcod efor connecting the Remote app.) Appears to be an issue with iTunes broadcasting Home Sharing, even thougt it says it is on.

I recently purchased Windows 8 laptop and installed Office 2013. I then installed iTunes. After moving all my music to the new PC, I got iTunes to import it and sync it to my iPod (3rd gen). However, I cannot get iTunes to sync my Outlook Contacts

I recently purchased a Windows 8 laptop and istalled Office 2013. I then installed iTunes. After moving all my music to my new PC I got iTunes to import it, and then synced it to my iPod (3rd gen.) However, I cannot get iTunes to sync my Outlook Calendar or Contacts with my iPod. When I try it crashes Outlook. iTunes continues to try to sync, but when it finishes my Calendar and Contents are empty (ERASED!). I have de-installed and re-installed iTunes (according to Apple's instructions), repaired Office 2013 and Outlook, scanned for viruses (etc), cleaned out temp folders, defragmented, etc., etc., etc. Has anyone seen this before, and does anyone know houw to fix it? (HELP!)

Well, I guess I have to download some other software to make my apple product work. Really great stuff you guys sell. I will never buy another apple product. My Iphone, Ipod and Itunes are junk

I have files in my iTunes media folder that somehow are not in my library. How do I get iTunes to scan my media folder and add missing files to my library without making a copy of each file in the same location?

I have files in my iTunes media folder that somehow are not in my library. How do I get iTunes to scan my media folder and add missing files to my library without making a copy of each file in the same location? If I use add file / folder to library, it scans the folder and then makes a copy of any file that is not in my library in the exact same location; I recal in older versions of iTunes being able to just drag my media folder into my library and it would update missing links.

Only the songs that are connected to iTunes will be copied when you consolidate to a new folder.
Splitting the media folder away from the usual location makes it harder to move iTunes in the future.
Are you go move everything back once you've tidied up or are you going to leave it that way? Either way I'd recommend you create an iTunes folder at the new location, an iTunes Media folder inside that, and consolidate to this new iTunes Media folder. You should also use the option File > LIbrary > Organize Library > Rearrange files in the folder "<Media Folder"> if you have not already done so.

I have lost my itunes library after updating it and keep getting a message saying MSVCR80.dll is not installed when I try to uninstall/reinstall it???

I have lost my itunes library after updating it. Have tried uninstalling/reinstalling it and it gets so far then tells me that it cannot be installed because MSVCR80.dll is not installed on my pc. I have no idea what this is and have googled it, followed links to sites that say they can fix it, only for them to scan, tell me I have 3 thousand issues and then want me to pay $30 dollars to fix it for me. This message also appears on firing up my pc too.
Can anyone help please?

I've been through the exact same thing and cannot seem to get an answer here. When you go to Manage Storage, does it have something at the top like "19.1 GB of 25 GB available"? I only have a Mail account with 5.3 GB in it and a Backups account with 553 MB in it. Obviously, these don't add up to 19.1 GB. There was no change in any of these numbers when I deleted all the same files you mention. With the free Mobile Me storage expiring next month, this is something I'm pretty concerned about.

I seem to have a corrupted iTunes library. I can't transfer the library to an external drive. The transfer hangs up on a specific tune. Anybody have any ideas. I am running OS 10.6 w/ a 2Ghz Duel core processor.
