Hi, @ruah I'm a fan of 7-ZIP too 7-ZIP and Winrar both this freeware is really useful apps.
If you look at the interface of the two apps you'll notice that they are almost similar.

Pros:

• The 7-Zip is a file archiver with a high compression ratio.
• The 7-Zip can use on any computer.
• Self-extracting capability for 7z format.

Cons:

• Non for this powerful file manager.
