CCleaner is GREAT...greater than even Piriform realizes! :-D
Piriform should BRAG that CCleaner also trims SSD's (= re-sets bits to zer0)!!
THIS IS VERY IMPORTANT because ~75% of all computer users (especially businesses) in the world STILL USE Windows XP.
Every month now a million more XP users buy a new SSD (solid state drive) which must be manually trimmed to maintain top speed. XP does not support auto-trim unlike Vista and Win7. Yet only 15% of users have Vista or Win7.
While a few (slow) programs allow XP users to MANUALLY trim an SSD, NO program exists--EXCEPT CCleaner--to AUTOMATICALLY trim the SSD.
For example, "AS Cleaner 0.5" is the most popular trim program for XP users, but takes 15-30+ minutes to manually trim a 100 GB SSD. Worse yet, the computer is too slow to use during the trim!
In contrast, it is easy to configure CCleaner to quickly auto-trim every time it deletes files! So, an SSD ALWAYS operates at peak speed without any special attention! Wow! :-)
Simply choose "Options, Settings, Secure Deletion "Simple Overwrite (1 pass)", and select your drive(s) and "Wipe MFT Free Space"
HEY, Piriform, start bragging to the world! Tell the 250,000,000 XP users buying SSD's how great CCleaner is!
I have used CCleaner since 2009 to auto-trim my (4) four SSD's in my desktop and my laptop. Phenomenal!
Thank you, Piriform!
