Is it safe to delete duplicate files with System Ninja?

I recently read some recommendations about System Ninja & how well it works to scan & find junk files in your system. I ran it on my win10 laptop a few days ago. Its a PC that I freshly reinstalled the OS in early Sept. It found all kinda of junk/ temp files. I deleted them & freed up a lot more space. I was very impressed. The program has a feature to scan for duplicate files too. I did that scan. Unlike the junk scan that took about 3 minutes, this scan took a couple of hours. It found a TON of files. I looked some of them over & didn't recognize them. They looked to be duplicate files or files with very similar names. I was going to delete them but got worried. It just seemed like sooooo many files, 100s if not a 1000 files!! I was worried I might be deleting important system files along with the junk duplicate files.

-Has anyone done the Duplicate File scan with this program?

-If so did you delete all the duplicate files it found?

-If you haven't done either...in general are duplicate file scanners/deleters safe to use?

Thanks!

Are you short of space on your hard drive? If not forget it Win10 has a perfectly good system cleanup facility, use it and forget the others that could cause you a multitude of problems.

If you are short on space consider a second HDD, or moving all those saved pictures, video clips and music to an external USB drive.

Smart!

For sure, similar names means nothing.

I agree 100%.

Unless you are running critically low on space, having extra files on your drive causes no harm or performance problems whatsoever.

I recommend you run Windows own Disk Cleanup.

Also, it is likely many of those duplicates were found in the Windows.old folder. This can be deleted but if you do, you will not be able to restore to the previous version should something go wrong. So should you delete it if all is good? There is no need as Windows will automatically purge that folder after 30 days.

Yep I have a ton of free HDD space. I was just curious if all those files were slowing my system down. I won't bother with the Dup File scan. I'll do the built-in Disk Clen option from time to time. Thanks for the advice!!

No. Files just sitting on the hard drive have no affect whatsoever on system performance, as long as there is plenty of free disk space left for Windows to operate in.
