Thank you for your post.
If you are receiving a -43 error on a shared Windows folder, there are two possible causes:
1. You do not have full read/write privileges to the server. Check with the Server Admin to verify.
2. You have a file name with illegal characters. That is, non-alphanumeric characters.
In ScriptMaker, you can create a script using the "Export Records" step that allows you to specify the output path. The "Export Records" script step also adds a secondary (and tertiary, etc.) file path if the first path is not found. FileMaker Pro will NOT open a shared folder. That will need to be done either manually, or have your database file open another FileMaker database file on the shared server to open the shared server.
