Virtual CD / DVD – ROM drive works and behaves just like a physical CD/DVD drive, however it exists only virtually. Image files can be mounted onto a virtual drive from your hard-disk or from a network drive and used in the same manner as inserting them into a normal CD/DVD drive.
There are several virtual drive out there. Personally, I prefer DAEMON tools (I use that at home) which has lot of function. However, it is not free for business / corporation use. Another one is SlySoft Virtual CloneDrive (use in office) and is completely free. 
I am using SlySoft Virtual CloneDrive at home but it can’t mount .uif file. Do you know which software can mount .uif file?
uif file type? Never heard of it.
Use DAEMON tools la. It is much better than SlySoft Virtual CloneDrive.
