Found another bug:
If you run the archiver not from the same directory like this:
C:\Users\Administrator>D:\ioFTPD\scripts\jeza.ioFT PD.ArchiveScript\jeza.ioFTPD.Archive.exe
It simply does nothing, this also is the case in Task Scheduler, i could create a .bat file for this, but it should be a simple fix in the script itself + other ppl won't have to do it aswel
