How do you find the "iT 1.tmp" file for iTunes?

Hello,

I am currently having problem with my iTunes library. A couple of days ago, very randomly, most of my music and movies disappeared from my iTunes library. I had recently updated iTunes, but it was a week after the update that this happened. All of my music and movies that I had added through importing CDs or copying from a hard drive were no longer in my library, and all of the music I had purchased from iTunes had the iCloud symbol next to them, and needed to be re-downloaded to actually have them on my computer. My iPod also didn't recognise it as the same library, asking if I wanted to remove all music on it before syncing.

The strange thing is that all of my music and movies are still in the same place; they're in the iTunes media file and everything is there, it just doesn't appear on my library. After a bit of searching I found out that others had had the same problem, and it was apparently fixed by deleting the "iTunes library.itl" file and renaming the "iT 1.tmp" file with "iTunes library.itl". The only problem is that I can't find "iT 1.tmp" anywhere.

If anybody could help that would be amazing, as I have lost 3000 songs and I have no idea why. It would also be much too time consuming to import everything again.

Thanks 🙂
