WBFS manager doesnt always delete its temp files.
i recently moticed that my primary computer hdd was missing about 30 gb. The culprit was a wbfs temp file with about 7 iso's sitting pretty
on vista check Root:/users/(windows username)/appdata/local/temp/wfbstemp/
appdata may be a hidden folder. so first disable hidden folder hidding in
tools/folder options/view/ check "show hidden files and folders"
this problem may be relative, but if youve noticed a lose of hdd space this may be to blame.
btw im using WFBS 3.0 and its the newest release that im aware of.
This occurs if you have WBFS Manager handle the unraring for you. If you manually unrar and then transfer the ISO directly then this doesn't seem to happen. Clearly Winrar has better temp file management than WBFS Manager.
