How to stop Mac from auto-saving versions of large file?
I have one specific Keynote file, 3.8 GB large, that I update almost every day. (Tons of photos for design inspiration. I like having them all in 1 place to mix & match)
Every time I open it up, add/change something, close it, I lose 3.8 GB of space on my HD because it automatically saves a "version"! (You know, when you want to File > Revert To >") Yesterday I had 130 GB worth of old versions of this file, and I was able to delete all of them at once, thankfully. Which freed up a massive amount of space. But I don't want to keep doing this all the time. Losing 3.8 GB & counting, each time, has been confirmed by checking About My Mac > Storage, and witnessing the loss in space after checking a 2nd time after I close the Keynote file.
Is there any way I can turn off this auto-saving feature JUST for a specific file? Or JUST for Keynote? Or do I really have to do it system-wide?
Thanks in advance!
