Doesn't matter whether you open the file for writing or only for reading. The drive will be blocked. But I just remember one other solution. If you set the .WIN file attribute to "read only" in Windows then the QPCs will open the file in a different mode. In this mode two or more QPCs can actually have the file opened *at the same time* because they can be sure that no other application will be able to corrupt the cached FAT data.
