A client recently sent me a .RAR file which I was unable to open. A little internet research revealed that .RAR files are compressed archives similar to .Zip files. RAR has the benefit of creating an archived file which is 8 to 30% smaller than Zip archives.
Like .zip files, .rar files require a piece of software to extract or uncompress the data. There are lots of free solutions out there but this one from 7-zip.org worked very well for me.
I use WinRAR. Works great.
I must confess that I know about nice tool,which works with rar files-fix rar file header,it has free status as how as I remember,utility can process RAR files, that were corrupted as a result of virus infections, hardware failures, media errors and other problems,program is a good alternative to expensive data recovery services, it saves a lot of time, providing the same effectiveness,was developed to reconstruct corrupted archives in RAR format, this program provides good chances for successful recovery even from seriously damaged RAR files,effectively works with RAR archives up to 4 Gb.
