Document Revisions are taking up 130 GB of space on my HD
For the 2nd day in a row, I had a message pop up on my Macbook telling me something along the lines that I was running low on available space on my HD. It didn't give me any options to do anything.
So I checked 'About My Mac" > Storage, and 200 GB was taken up by 'Other'. I had no idea what could possibly be taking up so much space. Long story short, after downloading a second different app that checks what's taking up space on the HD, and how much, I discovered that "DocumentRevisions-V100" was taking up 131 GB! Wow.

1 - Can I delete all those document revisions without affecting or ruining the current file?
I rarely ever find myself going to File > Revert To and needing an old version of a file. And if I do, it's never all THAT important. So I don't think it would be a big deal if I deleted all of them. Of course, unless it affected my current files. Then there'd be a problem.
Note: I MIGHT have an idea of what's causing this. I have a certain Keynote file and nearly every day I'm opening it, copy & pasting pictures for design inspiration. The file is about 3.8 GB big and has around 2,000. If it saves a new version of this file every time, it must have definitely accumulated over time, right?
Note: I do not use Time Machine or anything for backing up. However, I do have MicroMat TechToolPro which I once paid for in attempt to save old files from a corrupt HD on a separate computer (didn't work) - but I still have the app on my Mac, and it seems to be backing up some of my stuff. 9GB total worth of 'Directory Backup'.
Basically - where should I go from here? I would like to clear up as much space as possible and this seems to be the #1 problem. If I can delete all or most of these Document Revisions, without affecting any of the current versions, I would appreciate any help in accomplishing that.
Thank you!
Note: I'm running Yosemite 10.10.4 - MacBook Pro (Retina, 15-inch, Late 2013)
OS X Yosemite (10.10)
