Incorrect Folder Size in Memory
 

Hello,

My Sound folder ("Audio Clips") contained 20Go of music.
I deleted all my music while the N900 was connected to my Mac through the Finder.

Even though the folder is now empty and is just 1Ko, it is always marked at being 20Go when I check my Memory status in the Settings.

I cannot transfer anything on my N900 that would be larger than the assumed (wrong) free space remaining.

How can I fix this?

Thanks a lot for your help.
