This is about my 8 year old ACER Laptop.

I regularly delete old restore (backup points) and only keep the latest. But something keeps filling up my local disc "E". I have no idea what is doing the filling. At this rate, my "E" disc will be 100% full in about 2 months !

What to do?

Thanks to above link, I was able to fix the problem. Thanks !

What was taking up the space?

I had to delete Backups dating back to 2015. My "deleting efforts" using the "the deleting tool" that the system provides, simply never worked.

Thanks again.

No problem, glad to be of help.
