USB drives use a "journaling" file system... JFFS ... I do not know
where... but I heard something like that... Does it add some overhead too?

NTFS is a journaling file system. There's no such thing as a file system
called JFFS at least not one that Windows can use.

I read... Journaling Flash File System... It's supposed to be used in flash
drives... But... I'm a little confused.... As you said NTFS is a journaling
file system... So, Is that the file system (JFFS) that is refered to when
talking about usb drives? or.... is some low-level file system (if such
thing exist) and... Does JFFS exist even when pen drives are formatted
with FAT32?

Well, yes, windows use NTFS or FAT32... but where do this JFFS fit in the
scheme....? It's related to Flash drives.... the only thing I'm sure of...

Could it be that the file system USB drives use is some like a virtual file
system... Maybe it report like FAT32 or NTFS but underlying there is another
file system? (Yeah I have no idea what I'm talking about... just a
philisiphical question...)

I read you, please don't get mad. NTFS is a journaling file system; I assume
tha FAT32 isn't a journaling file system.... I'm just still confused...

thanks....

JFFS is a Linux file system for flash drives, kind of equivalent to
NTFS.

FAT32, or just plain FAT are not journaling files systems as you
suspect.

Glad to help. I didn't really know about it to begin with either, but
you got me curious about it...
