macos - Mac Lion OS X - I deleted files, but the disk free space is not increased

I had on Mac Lion OS X just 0.5GB of free space, so I deleted like 15 GB movies => OS X wanted to confirm this operation by filling out the password => I did it and the files were deleted.

I checked again the free space on disk and there is still 0.5GB. I have tried to restart system, but nothing has changed => still 0.5GB of free space.

The thrash is empty. What is wrong with Lion OS X? I have Macbook Pro.

Thanks.

Answer

Trash ownership is likely to have been set to 'root'.

Go into your terminal and type

sudo chown yourusername .Trash

This should fix the problem.

Hope this helps!
