How to: Fix iTunes Library file error (-48)
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)“.

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?

Yep, this also appears to have worked for me after a long, long search.
Thanks to the OP.

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

This worked for me, using windows XP and an iPod classic. If I thought you would accept a marriage proposal, I would ask you, for you sir are my newfound true love.

Graham, I’m thrilled and flattered. But I already have a lady wife.
Glad the trick worked for you!

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.

i didnt used this but i figured out a different way, i set my ipod into disk mode and plugged it in2 my computer 4 an 1hr and half then told my computer to check 4 errors and error 48 didnt show up agian so theres 2 ways of doing this.
Posted at 8:41 pm on Jul 5th
I did the step but, I get another error saying…
“error occurred applying attributes to the file: c:/documents and settings…/itunes library.itl access denied.”
what do i do?
Posted at 7:35 pm on Jul 23rd
Thank you so much for this assistance. I had tried other measures but without success. I found it woeked if I made the changes with my ipod connected.
