Re: TZF - "Default Directory" & reindexing

Brian,

When you ChDir (DataDir) and set Active := true Topaz looks in the current
directory (DataDir) and opens the file. If you  FileName := DataDir +
FileName and then set Active := true Topaz will look in DataDir for the
file.

I don't remember the name of the procedures right now but they will parse
the filename and return the directory and the filename. This will give you
the filename for each time you run the procedure.
