A stupid Question

I know this question will have been asked before but can’t find an answer relating to it.
What is a .BAK file ?.
:blush:

It’s a backup of your current .cpr, created according to your Auto Save settings in Preferences>General.
(and… there is no such thing as a “stupid question” :wink: )

HI vic_france.
Thanks for that man.
At the moment Auto Save is on 15 minutes so it will save the.cpr every 15 min as a .bak and max back up files is 10 so I adjust that as I want.
