file disappear after be deleted but no space freeing

Hi,

First of all, sorry for my english.
I use winscp 4.0.6 to connect to a Debian ETCH.
I have deleted a file in /root but after this and a "dl -h" space used seems to have not change.
I tried in SSH with sigwin with a other file. There is no problem by this way.

Do you have any idea ?

Best regards.

Paul

Solved.
Probably a problem in file system.
