Hi,

Enter a small routine that checks desired directory for desired filename ... if exists abort or write to temp-file leaving a flag somewhere that the elder file is not up-to-date for next access ...

... but why are you working with textfiles? why aren't you using one database on central server?

Best regards, Raisor
