It used to be, under DOS, that ".COM" files were loaded and
"executed" even if they were text. Then, when the ".EXE" file
came out, it would be executed if the first two bytes were 'MZ' so
you could make a text file with the first two characters "MZ" and
save it as "CRASH.EXE" and that's what it would do. All ".BAT"
files were assumed to be interpreted by 'COMMAND.COM', the "shell",
as scripts. This means that you can make a ".BAT" file called
"COMMAND.BAT", with interesting results.

When FAT-32, NTFS, VFAT, Windozes file-system(s) were developed
all bets are off. Long file-names are the result of a 'container-file'
concept and anything goes.

So the only way to guess at these file's execution capabilities
is to read the name --and it's a bad guess.

If the files are NOT set to 'executable' as read by Linux, then samba
will not work. For the files to be visible to WIN/Clients, they
must have all bits set. This 'feature' can be used to make DOS/Win
files temporarily off-limits to WIN/Clients (like during a backup).
