--- Comment #3 from Rico kgbricola@web.de 2013-01-28 07:56:44 CST --- You have not stated which app you were using, so we could not help you, I think. But I think it may be PDF Creator or so ... Did you had that installed? You may have a look here http://forums.pdfforge.org/discussion/10469/helperservice-exe-belegt-komplet... , it's in german ...
If a user should not be able to fill the disk, you may use a disk quota ... but that's another issue and has nothing to do with wine.
