The Save File action is used to both save and copy files. However, it will not copy a file from one drive to another when the Overwrite if File Exists option is enabled, and it doesn’t seem to matter if the source file actually exists in the target folder. For example,
The shortcut works with the overwrite option disabled. If the source file exists in the target folder, a duplicate with a counter is created.
There are a few workarounds, such as deleting an existing file in the target folder before doing the copy. I wondered if anyone has encountered this issue or found a better solution. Thanks!
BTW, the same behavior is observed with the Move File action, so perhaps this works as Apple wants it to.
