New version 5.55.7108 takes up a lot of extra space on C: drive. Is that normal?
Can you give a bit more info?
How much space does it take up?
What operating system?
I am using Windows 10. After the upgrade, the used space on C: increased from 27.7 GB to 29.6 GB.
The Cleaner has been updated from 5.52.6957 (64bit) to 5.55.7108.
Updating may have created a restore point, although I can't recall in the past if it triggered one to be created or not. Then again yesterday was updates Tuesday for Windows so if your computer has installed those that would've gobbled up some disk space including making a restore point.
