WinMount

   WinMount can mount ZIP, RAR or ISO file to a new virtual drive so that you can use those files inside directly. You donot need to extract them first. This save your time and disk space. WinMount support of mounting ZIP, RAR, ISO, CUE/BIN, MDS/ MDF, CCD, BWT, CDI, NRG, PDI, B5T and ISZ formats. We also suppor mount a folder to new drive. You can also create a disk image file and mount it to a new drive. You can choose if write data back to disk image file or not. This makes you away from virus.
For instance, you can mount a ZIP file ,say c:1.zip to a newly created virtual drive. After you execute the corresponding command(File-Mount-Mount Files) in the menu, your operating system will immediately notify you that a new device has been found, and a drive letter say H: will be assigned to it. when the mounting process is finished, you can find all the original files inside that zip file under H:. If you find some sort of another RAR file say 2.rar in H:, donot worry, this RAR file still can be second-mounted to another drive say I:, hence we can play the hot.avi(we assume that it exists in 2.rar) directly. Enjoy !
