FileVista HDD usage

when I removed the old FileVista 3.x version from the server I noticed that folder was 800 MB in size.
Which files causes FileVista to eat the HDD space ? is there any "Upload" temps that are not deleted when we delete the files from the folders or ?? 

Thank You

Best regards

The HDD usage should be caused by the temporary files in folder FileVista\App_Data\temporary.
Actually these are left over files from unfinished uploads and zipped downloads.
However, I believe you will not see much left over files with version 4.0 as we have improved handling upload errors.
Note that you can safely delete the files in this folder.

thank You for reply Cem, I understand now.....
