If you're anything like me, you'll find iTunes to be an essential part of your working day. Whether I'm listening to my favourite podcasts or concentrating with the help of some soothing music, iTunes stays running all through the day. Which is why I started to become pretty worried when a recurring error started to appear recently. Each time I start iTunes, I receive an error warning stating that "The iTunes Library file cannot be saved. An unknown error occurred (-48)".

iTunes error (-48)

It took me a bit of time to work out how to fix this problem, so I thought I'd pass on what I found. This error basically stems from iTunes not being able to write its Library file to your iTunes folder. To fix it, simply find your iTunes folder (located in My Documents > My Music, in my case), right click the folder's icon and choose 'Properties'. From here, click 'Advanced' and make sure that Fast indexing is switched off for the folder. Also, make sure that in the main properties dialog box, 'Read only' is completely unchecked.

This worked for me, but let me know if you're having further problems with error (-48).

    I have been experiencing the same issue for the past week or two on a Windows XP Pro machine. I tried the suggested fix and it appears to have worked! Thank you.

    This worked the first time I tried it. However, my computer keeps checking the Read-Only box everytime I close the "Properties" window. Any suggestions as to keeping Read-Only unchecked?

    The (-48) error message on iTunes 8 only comes up when I plug my iPod in. It will not let me look at anything in my iPod or even see how much memory I have left in it. Also when I try to put songs in my iPod it tells me that, but the songs still show up and play on my iPod. It is annoying thought because I bought the game Phase for my iPod and you have to drag the songs to that folder too! so now I can't play any of my new songs on there. Can you help me?

    I have been experiencing this and am grateful for the advice, its given me a clue as to what is going on but unfortunately doesn't help solve it since on top of the error message all my music folders after c (Cameo!) have vanished. The music is all still there - i can access through iTunes - but I cannot access the iTunes folder since it comes after c and have no idea how to access it. I've tried everything and the only thing I can think of now is to reformat the whole system. Bah.

    Did not work for me, there is no advance option available!!! nothing works, and its funny, Apple offers not advice to fix this unless you call the, of course they want to charge you!! I think this is Apple's idea to screw the consumer and hope they will buy a new one, got news for them, no way!!

    I've tried doing this, however once it gets to the Temp File.tmp it says I don't have access to change anything (even thought I'm the administrator!) I have no idea what this file is, but its only occurred in the last half an hour after downloading 3 songs through Limewire. Help!! :-|

    A Combination of your and Chan's Advice helped. THANK YOU SO MUCH, this shit was driving me crazy.

    "Your advise didn’t help but I deleted all the temp files in my iTunes folder and that solved the problem"

    Thanks again guys, seriously =).

    I tried to follow various advise to fix this problem, but it all seemed crazy. Here's the way I fixed it: I did nothing - except to open and close iTunes several times and the problem went away.
