Button that creates '.bak' backups for any number of selected files.
If a .bak already exists for a file, it will create .bak2, .bak3 and so on.
Works even if each selected file has a different number of .baks already
Allows changing .bak extension to anything (See 'backupExtension' variable)
Example Result:

I love the .bak script. But I'd like to see it modified so that .bak* files get created in or moved to a designated backup folder so that you don't have to move them after the fact.
If you want to add the date and time to the backup filename, (e.g., MyFile.xlsm_10-10-2022_06-02-53.bak), add {date|MM-dd-yyyy}_{time|HH-mm-ss}. Change this:
I tried the script, but the backup file is created in the destination pane. Should this not be avoided by the "here" argument?
(Is that the reason to avoid "here" in scripts?)
What do you mean by "the backup file is created in the destination pane?" Using HERE, The backup file should be created in the directory that the file you're backing up resides. Where is your backup being created?
I use dual display mode. It was created "on the other side". When I used the script for a file on the left side the bak was created on the right side and vice versa (in the current visible tab).
Ok, I deleted the word HERE from my script, and the backup still gets created, and in the correct location, with a dual window open. This is the script without the HERE:
Yes - in the version without DUPLICATE the "here" has no function (any longer). But you have to define the sourcetab as destination tab like in my code snippet above.
Or you have to use "Copy DUPLICATE" - then no "HERE" or "setDestTab" is necessary.
But is it intended, that the "HERE" has no function any more? I assume it worked in the past.
EDIT: If the selected item is a folder nothing happens.
