As a knee-jerk reaction, I always ask "why" ... you see it more in the "personal" world (i.e. hobbyist), but I also see it [more than I like to] in the corporate world ... it's always the techno-weenie who wants the latest thing and talks management into the newest gizmo. -- Economists can certainly disappoint you.

You didn't address the OP's original request. It's not that they don't know how to do the conversion, but their concern is whether existing files are treated as "true" ext4 (extents) files after the conversion. They aren't - there is no "conversion in place" that happens, unless you off-load the files and then copy them back into the filesystem. Even if you run a defrag utility, it won't reconstitute a file into an ext4 entry if it's not considered for de-fragmentation. -- "I can't complain, but sometimes I still do." - Joe Walsh <<< Remove YOURSHOES to email me >>>

An "average brainless windows user" (aren't all Windows users brainless?) won't know what FAT and NTFS are. -- "The porcupine with the sharpest quills gets stuck on a tree more often." <<< Remove YOURSHOES to email me >>>
