Hi, I know this is off-topic, but I know this can be done under Linux using the Loopback device, so I'm wondering if a hopefully free and easy equivalent exists under Win32 systems. I don't need encryption so products like Bestcrypt and Scramdisk seem like overkill to me. Here's my problem. I have 3.6 gigabytes of MP3 files in many subdirectories under one main directory, which I wish to burn to DVD. Unfortunately, many of the filenames and/or pathnames are too long for the UDF or Joliet filesystems used on CD's and DVD's. My solution. If I could make a Fat32 filesystem in a file on my Windows machine and mount it as a virtual drive, I could then copy the MP3s over to this virtual filesystem. Then I could burn that and the tool to mount it onto a DVD. If forced to use encryption software I'd put in a really dumb, easily guessable password and include a text file on the DVD which contains the password, in case I ever forgot it. Security isn't an issue here, so once again products like Bestcrypt seem like overkill. Does anybody know of an equivalent of /dev/loop for Windows? What I'm wanting to do is to make, say, a FAT32 filesystem in c:\myfat32.dsk, let's say. Then use some tool to mount that as, say, drive X:. Any help would be greatly appreciated! Thanks, Jayson.
