This is actually a very common trick in DOS/Windows, and Samba supported it back in 1.9.16 or so. Anyone on the list with Borland experience??? --dave -- David Collier-Brown, | Always do right.

As far as I know multiple users make use of some of these. Have you actually tried this and found a problem or do you just suspect there may be a problem?

We do not use OPLOCKS. These things seemed to cause failures. All other problems we have are bugs of the BDE database engine. Paradox sometimes crashes, especially if the computer running Paradox has small memory. Jochen
