But then I realised that only that "fake oplocks" is unsafe. The fact that other files are not oplocked means the files are not cached by the user, so "safe". Thanks for all your replies.

If you guarantee that only one user will ever use that db simultaneously, you're probably fine. If you have multi-user access, "fake oplocks" will make the application eat your data. Volker Hi Volker, I know that, that's why I will give it a share of it's own. That application is "write one/read many". Is there an explanation for the fact that when I run the application in dosemu on a linuxbox, the files are opened with an exclusive lock, while under "regular Windows", the files are opened without locks ? And that's on the same share. Now that I think of it, I don't see any files opened with oplocks ! All my locking options are default. Why are there no oplocks ?

When I run the application with dosemu (i.e. fast respone), the database-files are opened with an exclusive oplock. When I run the app in Windows, there is no (none) oplock. Does this ring any bells ? P.S. is it possible there's a bug in swat ? The headers of Open Files are not all OK, and the user-id is not "reverse resolved". Or is it Webmin that does this ?
