List - File Type
This field displays the ProDOS file type. Types that don't have three-letter abbreviations assigned are shown in hexadecimal notation. Archived disk images are listed simply as "Disk".
Forked files are noted with a plus sign ('+') following the file type. Folders appear with a trailing slash ('/'), and will usually appear as "DIR/". However, it is possible (but not recommended!) for a folder to have a different file type.
Macintosh files stored in a ShrinkIt archive may be displayed with a 32-bit Mac file type instead.
File types from non-ProDOS disks are converted to the most appropriate type. The following conversions are used:
DOS 'T' TXT
DOS 'I' INT
DOS 'A' BAS
DOS 'B' BIN
DOS 'S' $F2
DOS 'R' REL
DOS 'A' #2 $F3
DOS 'B' #2 $F4
Pascal Untyped NON
Pascal Xdsk (bad blocks) BAD
Pascal Code PCD
Pascal Text PTX
Pascal Info $F3
Pascal Data PDA
Pascal Graf $F4
Pascal Foto FOT
Pascal SecurDir $F5
Files given "$Fn" types have formats that are not well defined.
