I have created a script that uses the step "Save a Copy" to save a copy with a dated filename (e.g. Backup_2016_01_11). What I want to do is to make sure I do not execute the "Save a Copy" step if the file already exists running on my iPad.
Using the following conditional works on my laptop, but does not work using FileMaker Go on the iPad:
If [ GetContainerAttribute ( $save_filename ; "externalSize" ) = "?" ]
Save a Copy as [ "$save_filename" ; copy ]
Show Custom Dialog [ "Backup Failure" ; "File already exists - no overwriting permitted" ]
Any ideas on how to keep from overwriting an existing file on the iPad??
