incomplete dirs - zipscript issue?

[qba]

The problem is as follows:

When i upload a set of files following an .sfv file everything works fine except one thing that unfortunately goes wrong. On every file uploaded a dir is usually created stating, for example, how many % are done. When the next file is created that dir is removed and a new is created. My problem is that those INCOMPLETE dirs are not removed/overwritten. When a release is complete I have one COMPLETE dir, and one dir after every file which was uploaded ie. "2F checked" "3F checked" "4F checked".... up to for example "44F complete".

Is it a ioBanana config error?

Thanks
