Where are the hidden thumbnail cache files?

As far as i can see, imovie saves the imported/captured movies into the /movies/imovie Projects or Events folder.

However, when i move the entire imovie projects or Events folder into the trash. Even after i use Secure Empty Trash and Disk Utility's erase free space, whenever i use Date Rescue II, i still can find a lot of thumbnail images from some of the movies.

This is making me feel so insecure that someone can still retrieve my files from my computer using simple recovery software when i want to send it for repair or to sell it.

I search everywhere in the forum and the net but i can't find the answer.

Can anyone advise me where is the exact location that IMovie hides this files?

Macbook Pro, Mac OS X (10.5.7)

Thanks, i already searched under /Movies/iMovie Events/YOUREVENT/iMovie Thumbnails and iMovie Cache/
I deleted everything inside and used Secure Empty Trash and Disk Utility to write over free space. But i can still find thumbnails from some previous movies.

Any ideas?

In that case, I suspect the issue is with the caches on your hard drive. You could have a look in /user/Library/caches for iMovie files.


Thanks nik,
But there isn't any cache file in there.

Or you could download Onyx (free utility) and get it to clear all your caches, the disk utility to overwrite free space, then check again.

There are other ways to clear caches, but Onyx is simple and it works


Tried that before too. Didn't work.
