Winrar is a great tool used for compressing files. It also has a command line tool called “rar.exe” to compress files, in case you want to batch it up. Here’s an example of the most common switches I use.
"C:\Program Files\WinRAR\rar.exe" a -m5 -r -ep1 "C:\temp\Work\Upgrades\2010-02-06\111.rar" "C:\temp\Work\Upgrades\2010-02-06\Post-Upgrade\"
First path is the location of the rar file to create. The second path is either the location of the file(s) or directory to compress.
options used -ep1 Exclude base directory from names a Add files to archive -r Recurse subdirectories (will compress entire directories) -m5 Set compression level to maximum
You can even assign a password to it using the -p switch
