I have a problem with my Archicad 11 scratch files!
The problem is that these files are occupying a lot of space on my HDD- 10 GB! The scratch files are in C:\Documents and Settings\User\Local Settings\Application Data\Graphisoft\ArchiCAD Cache Folder\ArchiCAD 11.0.0 INT R1 and i don't know if I can delete them from my computer?
Generally scratch files can be discarded with impunity. Just to be safe you can copy them to a CD before you toss them. The real question is why the software is not deleting them for you.
