Got a question. Can I make a subdirectory hidden like a hidden file? And if so, can I then access it like a normal subdirectory? If all this can be done, how? I think I may be asking a lot but hopefully it can be done. Thanks Jack

Below is a small assembly language program which will do just that. To create the two .com files, type the instructions below into a file named script, using a pure ASCII text editor. Then, with Debug.Com on the same diskette, type DEBUG<SCRIPT. This will contain two files, HIDE.COM and UNHIDE.COM. HIDE.COM will hide either both files and directories, and UNHIDE.COM will make hidden files or subdirectories visible again. Remember when typing in the following to include all blank lines and hit the return key after each line, including the last. NOTE: Although I would like to take the credit for the following programs, I didn't write them. I found them in some magazine (can't remember which) ----------------------------------------------------- N UNHIDE.COM A MOV BX,80 INC BX CMP BYTE PTR [BX],20 JZ 103 MOV DX,BX INC BX CMP BYTE PTR [BX],D JZ 116 CMP BYTE PTR [BX],0 JNZ 10B MOV BYTE PTR [BX],0 MOV CX,20 MOV AL,1 MOV AH,43 INT 21 INT 20 RCX 24 W N HIDE.COM A 119 MOV CX,27 W Q -------------------------------------------------------- Hope you find these useful. I use these programs to hide all files in my root directory (config.sys, autoexec.bat, command.com) so that the only things which show up during a DIR are directories. I haven't really used it much on hiding directories, but have tested it and it does work. Hope you enjoy them. -- Roy Brabson Georgia Insitute of Technology, Atlanta Georgia, 30332 uucp: ...!{akgua,allegra,amd,hplabs,ihnp4,seismo,ut-ngp}!gatech!gitpyr!duke ARPA: duke@pyr.ocs.gatech.edu

As long as you don't forget the name (and read-protect it) you can access it.

Simply use CHMOD by Gene Cohler (as posted to this newsgroup earlier). CHMOD will allow you set EVERY attribute bit on a directory or regular file. You can set the 'h'idden, 's'ystem, 'a'rchive, 'r'ead-only bit. Setting the 'r'ead-only bit, however, doesn't make a 'read-only' directory which would be very desirable. This is a limitation of DOS rather than CHMOD. It seems DOS only checks the attribute of the file you're about to delete rather than any attributes set for the parent directory. So, just change all the files in the sub-directory with: CHMOD +r *.* . Simple enough! Now, once these files and subdirectories are hidden, all programs like DPATH, SEARCH, and other such beasts can find the all of the files and subdirectories with no problem. I've 'uncluttered' my 10mb disk's root directory and it drives clients buggy that they can't 'see any files on on the disk!' Using 1-Dir or other superdirectory programs makes the files and directories easily visible. I set one of the directories will every attribute A,D,S,H,R. Different! Only draw back is, of course, you can't modify the 'd'irectory bit. Highly recommended... Please contact the author. The CHMOD programs comes with MSC V4.0 source, .EXE, and .DOC file.

Get a look at it with 'ls', a little less recently posted. Why make yet more special-purpose utilities when the general ones are so useful? All commands that access files in the directory work as before; you just have to know it's there. -- -- Chris Cullen UUCP: {ucbvax!allegra,decvax}!encore!vaxine!cpc Automatix, Inc.

Altering the attributes of files and directories is a painless,
simple process. Here the story:
--------------------------------------------------------------------------------
The DIRECTORY of a DOS Formatted disk ( as well as all SubDirectory
entries) is formatted as follows:
Field Offset Size Description
----- ------ ---- ------------------------------------------
1 0 8 Filename (Directory Name, or Label) - ASCII
2 8 3 Filename Extension - ASCII
3 11 1 Attribute (See Below)
4 12 10 UnUsed (should be zero's)
5 22 2 Time
6 24 2 Date
7 26 2 Starting FAT entry
8 28 4 File Size
Field 3 describes the file (or SubDirectory) as follows:
Bit Description
7 6 5 4 3 2 1 0
----------------------------------------------------------------------
-U - - - - - - 1 Read Only File
-U - - - - - 1 - Hidden File or Sub Directory
-U - - - - 1 - - System File
-U - - - 1 - - - Volume ID Label
-U - - 1 - - - - Sub-Directory
-U - 1 - - - - - Archive File
bits 7,6 are unused (0)
To modify a file or Sub-Directory simply change the attribute
bits using Debug or Norton Utilities (or any other utility that
allows you to read,modify and write disk data).
For example, to hide a file change the file attribute from 00H
(or 20H for Archive file) to 02H (or 22H). Changing the attribute
to 03H will make the file Hidden AND Read Only.
Another trick used by some people is to change the FIRST char-
acter of the file name to an Un-Printable character ( IBM graphic
character). This will make the file unusable by the KEYBOARD, but
may still be called by another program.
The same applies to Sub-Directories. I often purchase software, pop
it into the drive and type DIR, only to find ONE batch file (size
128 bytes) and NO SPACE AVAILABLE on the disk!!!! Upon running
Norton Utilities I find that ALL FILES are located in a directory
whose first character is a graphic character!!!
Well enjoy your disks with this info!!!iav1917@ritcv.UUCP (01/27/87)

Unless AT&T has placed a trademark on "CHMOD", the program supplied earlier on the net was a public domain program. It included source, documentation, and the program. While I did not compare the source against any Un*x or AT&T MS-DOS versions of CHMOD, it `appears' to be original. I wasn't aware that the AT&T version could touch sub-directories. I've been away from the 6300 for a long time and memory fades... Alan "A grain?!

[ . . . ] Aargh! You are right that altering the attributes of files and directories is a painless, simple process but I wouldn't call using debug or Norton painless - One typo and you've just wiped out your whole disk. Nearly every BBS has several programs for changing file attributes (usually called ALTER, HIDE, or CHMOD) to simplify this process. Some versions of MS-DOS (i.g. the AT&T version) also come with the CHMOD command.

As long as you don't forget the >name (and read-protect it) you can access it. Hiding directories is accomplished in exactly the same manner as hiding files, from a dos standpoint. You call the dos chmod command (I can never remember the silly function call numbers, so check your tech ref). Tell it to chmod the file and give it "hidden" or "system" attributes. If the "file" turns out to be a directory, dos still doesn't care. As for forgetting the name, it is trivial to tell the find first/find next functions that dos provides to look for hidden/system files. In fact, the only directory printing program I have made displays EVERY file, whether it's hidden or not. It works much like UNIX's ls -al would (showing the file attributes). Since it's so easy to find a "hidden" file, I wouldn't worry about forgetting the name. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% - Jim Frost * The Madd Hacker - UUCP: ..!harvard!bu-cs!bucsb!madd | ARPANET: madd@bucsb.bu.edu CSNET: madd%bucsb@bu-cs | BITNET: cscc71c@bostonu -------------------------------+---+------------------------------------ "Oh beer, oh beer." -- Me | [=(BEER) <- Bud the Beer (cheers!)
