Was sent a rar zipped file of pictures from Europe and no longer had a unzipper. Downloaded and installed 7, process was simple. Ran 7 against the rar zip file and it unzipped as advertised. Tried a zipping test to see how that worked and again worked OK. Have not used it for other tasks, but plan to do so.
User interface was not GUI friendly point and click, appeared to be somewhat old tech and was a bit surprised that the size of my test compressed file was not much smaller than the original. Could be that not being very familar 7 and just used the default settings, other setting may have resulted in a smaller target file.
Would recommed for someone that needs a free unzipper that appears to work. A BIG PLUS was that is was a CNET download, a company that I trust to not have problematic and risky downloads.
