"The iTunes Library file cannot be saved. There is not enough memory available."

Finally managed to fix my library, weeks of repairing damage from music files being "hidden." No problem for a whole 24-hours and I went to open my iTunes library which is on a 2nd internal hard drive and got the following message:

Any clues out there? iTunes and music library only thing on this 2TB drive, cleaned and polished. Over 1 TB free. I'm at my wits end,I have tried everything that I can think of. Permissions full control on myself on both iTunes.exe and iTunes library file.

OK, this message ...DR6, ties to a known issue of needing to update my bios, update USB controller/driver. The iTunes library used to be on an external USB hard drive. But it has not been for over a year. But a lot of files had to be brought from those lost hidden files on previous library backups on USB external drives.

I disconnected all all USB external drives and updated all drivers. I have not had the error message since. Posted to save the rest of the universe some time as Apple staff did not know root causes to this one.

Woke up this morning to the same error. At this stage, it is not USB driver interference. It is not security controls on me as administrator The only thing left is a steadfast refusal of Wiondows to allow you to move the Music library to an off C:\drive. Yes I point to D:\ for music. Yes I've adjusted setting as advised on the Net for C:\users\me to verify full permissions and avoid this error. Not screaming yet but really close. Anyone deep into this issue enough to have resolved? Anybody put there?

Have learned much since the last post. I've ordered a new custom computer, so I moved everything off the desktop onto an external 2 TB drive and connected to a 6-mo old Toshiba notebook. Re=built, re-connected, followed web advise and had all on e:\itunes\itunes media. Realized that the Windows version of iTunes makes no attempt to see if it has a file before it makes another copy of the file so Sing, expands to include a Sing 1, and s Sing 2, multiplying your library size everytime you are dumb enough to click File/Library/Organize/Consolidate. I spent several days manually deleting these duplicates and repointing itunes to the file. It was often easier to just delete the songs from iTunes and reload the corrected album subdirectory. But I still had a few thousand missing files. Interestingly, last night, I observed that the Automatically add to iTunes was not Automatically adding to iTunes so I went hunting. The folder location had changed without me to e:\iTunes Media and the Automatically add to iTunes did work from that directory. Before this burp, a review of the missing files from the sync listing was mostly iTunes U files, so I looked into the iTunes U and discovered that all of my Audiobooks, iTunes U files, and .TVShows had changed from these designations back to Music files so it could not sync TV shows. They were **** gone from the phone. They were still in the folder TV Shows but get info claimed them as Music. I highlighted all in TVShows and refiled as TV shows and it synced them back to my phone, I have had 2-instances of ERROR, Cannot save iTunes library file since the move to the notebook and external drive. Close iTunes and reopen and re-do whatever you just did in the last 10-15 minutes and all seems well.

I realize that the code requires the files to be in e:\itunes so I let the organize music files start consolidating again. It's about 1/2 done after running all night. Now I have to dig up some more hard drive space to move the old files to when complete, I have to seperate iTunes knowledge of where the old files were to avoid the file duplication problem. And I no longer trust iTunes to get all the files so I must keep them until confirmed. I still have numerous tracks missing from albums but nothing is read-only or hidden anymore so maybe this will get better. Re-building the library is a distainful activity because of the lack of metedata to the apps, so it will require me to re-folder 20-pages of apps. That's a long PIA for both the phone and the iPad so I'm trying to avoid it as much as possible. I love the end-result of a well synced phone and iPad but the user time required here has become horrendous. If I knew how to jailbreak from iTunes, I would. Growing to hate Apple software quality controls!

Might sound stupid but when that message appears just close and re-open iTunes....Worked for me!

I got this message last night. I have a new labptop with 8GB of ram, and my gadget said I was only using 28% of that, with nothing else opened. When this happened I was making alot of play lists, it poped up, several times and froze my computer.

Here's your fix and answer

hey thanks a lot for this tip. it totally worked. been using itunes for a day and the message has totally stopped popping out.

Your a life-saver! I was literary at the verge of pulling out my hair trying to fix this, even a open-close method that was working for others didn't help me.

Tried a number of things, but finally this helped. Thanks alot!

Same error "iTunes Library can not be saved there is not enough disk space", have over 300gb available so that's curious. Moving my library to a laptop from a desktop went rather smoothly until I started to redownload my purchsed material. While that was baking I added a couple of purchases to the download queue and whala - a string of error messages followed by a crash.

I wish Steve Jobs were still around, he would never stand for this poor a performance on an Apple branded product. I have had nothing but problems with iTunes from the start, duplicate files, crashes, lock ups, all on machines with huge memory and hard drive space.

Not that is should matter, but does anyone have better experiance running a Mac? Maybe the just do a shoddy job with development on the Windows side of things?

Common fellas, get your **** together

Yeah, there are really no such problems like this on a Mac--the issues seems to be with the Windows version of iTunes.

Just loading my wife's Xmas present (nano 16GB) and our 1st Apple device, this has just happened to me and then crashed iTunes.

I ended the process to close iTunes and loaded it up again, the files I transfered infact did not to the nano but when I tried again they went over fine.

I expected better than this from an Apple product especially when it carries a big price tag

System W7 Ultimate 64bit and yes I have the 64bit version of iTunes

Intel Core 2 Quad Q6600 @ 3.4Ghz

8GB RAM

2 TB HDD

AMD Radeon HD 6570

This thread seems to go all over not addressing the original error message post "...not enough memory.." is there a fix for this? (not to be confused "..cannot write to disk.."

I have the same issue as OP and there doesn't seem to any solution to this problem with the only reason being the fact that iTunes is not 64-bit and can't address more than ~1.5 GB of RAM.

I've read in other topics that iTunes will |never| become a 64-bit app because of certain libraries it utilizes. As such there can only be one solution which is something only Apple can do, which is to re-code iTunes to not utilize all the memory it does the larger the iTunes database / library becomes. I've set the Virtual RAM on my main HDD to 16 GB and several of my other external HDDs to have something as well but iTunes doesn't seem to take advantage of this.

Until this is solved I have found no actual workaround except maybe splitting up the libraries into 2 segments which to me is a very awkward fix that I still haven't even tried myself but seems like a logical fit.

I might as well mention that iTunes also seems to be complaining about "An unknown error occurred (-50)." which seems to go hand in hand with the previous error message.
