>ALL the functions discussed share the same weakness, they only report back on the current VFP session. Any table opened by another user or the same user in another VFP session, will not be reported properly...

Yeah, I see how my message was misleading, but I just wanted to make sure that it was said IsExclusive() and the rest can only tell you about the local VFP session.

Another thing about Sys(2011), it only checks the current work area, where the Is functinos have a parameter for the work area or alias.
