This controls whether non-DOS names under UNIX should be mapped to DOS-compatible names ("mangled") and made visible, or whether non-DOS names should simply be ignored. See the section on NAME MANGLING for details on how to control the mangling process. If mangling is used then the mangling algorithm is as follows: The first (up to) five alphanumeric characters before the rightmost dot of the filename are preserved, forced to upper case, and appear as the first (up to) five characters of the mangled name. A tilde "~" is appended to the first part of the mangled name, followed by a two-character unique sequence, based on the original root name (i.e., the original filename minus its final extension). The final extension is included in the hash calculation only if it contains any upper case characters or is longer than three characters. Note that the character to use may be specified using the mangling char option, if you don't like '~'. The first three alphanumeric characters of the final extension are preserved, forced to upper case and appear as the extension of the mangled name. The final extension is defined as that part of the original filename after the rightmost dot. If there are no dots in the filename, the mangled name will have no extension (except in the case of "hidden files" - see below). Files whose UNIX name begins with a dot will be presented as DOS hidden files. The mangled name will be created as for other filenames, but with the leading dot removed and "___" as its extension regardless of actual original extension (that's three underscores). The two-digit hash value consists of upper case alphanumeric characters. This algorithm can cause name collisions only if files in a directory share the same first five alphanumeric characters. The probability of such a clash is 1/1300. The name mangling (if enabled) allows a file to be copied between UNIX directories from Windows/DOS while retaining the long UNIX filename. UNIX files can be renamed to a new extension from Windows/DOS and will retain the same basename. Mangled names do not change between sessions. Default: mangled names = yes
