ps: and, btw, how freebsd knows there's a capital A in "A.txt~" ?
because it's stored on the filesystem in that way, i guess. being
case-insensitive doesn't (necessarily) mean a FS doesn't keep a case,
imho.
The reason is as follows: a.txt is an 8.3 filename and is stored on
fat32 in the old dos format. a.txt~ is NOT an 8.3 filename and is
stored on fat32 in the extended long filename format. Case information
is not stored in 8.3's file names. They're always the same case, but I
can't remember now if they're stored as upper or lower case. Extended
long filenames do store case information, even though windows ignores
the case (as was pointed out earlier). FreeBSD is displaying 8.3 names
as lowercase probably to mimic the tendency of unix filenames to be
lowercase. Windows displays 8.3 names as upper case probably to mimic dos.
The 8.3 names and the long names are stored separately whatever the name
format. FreeBSD displays the long name even when the filename fits the 8.3
format.
The directory structure of fat32 is still the same as from dos. In
order to create long filenames, Windows uses subsequent directory
entries to store the extra filename characters. If a filename fits the
8.3 format, Windows (at least Win98) does not bother to create the extra
entries for the long filename record. If there's no ong filename
record, how can FreeBSD use the long filename?
Later,
Micah
