What's the intention behind this? What's wrong with the software you tried to use for your usecase(s)?
I don't use Windows anymore, but if I understand correctly what you mean, the only times I used this were for encrypted TrueCrypt partitions, a RAM disk for temp and whatever else I felt like using it for (only do this if you have RAM to spare), and on occasion mounting disk backups. (Linux does all of those natively.)
