Plesk Disc Space Incorrect?

[ijob]

Why does my disc space on my Plesk VPS say that there is over 3gb of space used when I know that the files on my PC use up less than 1gb?

Please help

Its one of my domains. It says that nearly 4gb is used but when I go into httpdocs (where the files are stored) its less that a gb.

Whats happening?

disk usage includes not only httpdocs but other directories too:

check the amount of logs, they can eat space;
you can enable log rotation for this domain:
