kuihdez, WinMount certainly isn't portable. Not even the (illegitimate) "portable" version that can be found online is portable. Just tried the latest "portable" version of WinMount again and, after using it a few times, and after it restarted my computer several times on different occasions, I coudn't even delete the application folder because of "WinMTExt3.dll", even after unregistering that file. Luckily, FileAssassin (which is portable) managed to delete the file

. In addition, both, the "portable" and the normal install version of WinMount write a folder in the application data folder.
Of all the mounting tools that I tried and that conveniently and automatically create virtual drives at startup (unlike M$'s VCdControlTool, that doesn't), I found free "Virtual CloneDrive" (by Elaborate Bytes) to be the least obtrusive, especially after deactivating its automatic startup in msconfig (which makes it not mount the last used file on start-up, but still create the virtual drives on startup). Seems to be based on Daemon tools, but it's a lot lighter. Of course, it's not portable either.
