>However, being a Win16 app, FPW26 deals with short filenames (limited to 8.3 format). You could specify a filename longer than 8 characters, but only the first 8 characters would be used -- which could be a problem if the filename isn't unique in the first 8 characters.

You're right. I missed I was creating those files like this :

lcTemp = stuff(lcStationID+substr(sys(2015),2),9,0,'.')

Where lcStationID is a 2 char station identifier (A..ZZ).
