FM - Mount File System

USBwiz can mount up to 3 File System Medias that are independent from each other,

which means that all opened files and operations in one file system have no effect on

the others. This gives USBwiz very great capability of flexible switching between the file

system Medias and providing other valuable functions like reading from file in one

Media and write it back in other file in another media at the same time.

FM takes the responsibility of mounting the dedicated File System and doing any

necessary USB commands for USB memory.

Currently USBwiz accesses the first primary partition of a storage media by default.

However, it can be forced into mounting the second primary partition which might be

useful on some systems (iPods for example).
