Testing for import file existence?

[AJB_UMASS]

Is there a way to test for the existence of an import file, before actually trying to perform an import? We have a FM DB that is supposed to clear out all previous records, before loading a fresh set from a text file copied to the server from other machines. There's no point in deleting the old records if the new ones are not yet available (for whatever reason); since the old import source files are deleted after every successful import, how can we see if the new ones have arrived, so that we don't prematurely erase the old data?

If on the Mac you can use an AppleScript to do your import, or at least test for it:

tell application "Finder"

set importfile to "Reese_p1:Users:reese:Documents:ProductionSchedule:Saved:JobInfo.fp7"

if file importfile exists then

display dialog "your import command here"

else

--option function here, like email the admin

end if

end tell

Note that I defined the file path as a text string, not as a file. If it were a file then the script would error if the file does not exist.

It seems like it would be simple enough to

Set Error Capture [On]

Import Records

If [Get(LastError) <> 100]

Show Omitted Only

Delete All Records

End If

If the file exists (error does not equal 100), then the previously existing records are deleted after the import is performed.
