type in Disk Cleanup and probably gain some more GB's , it gets rid of old junk files and such, after that defrag if you have a HDD
Win 7 / pc
Last night I did a big spring cleaning & transferred a ton of video, music & image files to my external HD.
When I check my disc space, I see that I have 112 GB out of 446GB. (I was down to only around 53 GB) So nice improvement- But...
What exactly is taking up the other 300+GBs? Undoubtedly stuff I can't see, but I have no clue how to clean it/ make room.
I Googled around & saw terms like "shadow copies", etc.
