[] I'm looking for a way to compress an *entire* floppy (subdirectories and all files - boot sectors etc. aren't necessary) into a file. (This is so that I can post a collection of TeX fonts to CompuServe, so that people won't have to create two dozen folders and move the hundred or so files in one at a time...) Any suggestions would be greatly appreciated. -- James "Kibo" Parry kibo%pawl.rpi.edu@itsgw.rpi.edu userfe0n@rpitsmts (bitnet) 72347,2731 [Compu$erve]

James Parry askes for a way to compress a floppy disk, including folders and files, into one file suitable for uploading... I believe that the utility called "Magic Shadow" will do this, and that it's Public Domain too... I'm not 100% sure if it's available on CompuServe, but it's worth checking in the Utilities DL area... The only drawback to using a system like this is that it would have to be clearly explained in the upload description that a non-standard utility is required to extract the disk, but it *would* be far better than having to reconstruct the folders manually..!

You can use Shadow V1.03 (shareware) to compress an entire disk into a file. It should be up on your local BBS as well as the pay services. Lawrence Y. Chiu; University of California, Berkeley.

[] I don't know of a program that will do it for you as-is, but should be easy to write one along these lines: (The actual program can be shorter than this description!) 1) load the whole floppy into RAM as one block, using one call to Rwabs(). (First get the block of RAM using the TOS Malloc() call, NOT the C compiler's malloc()...) 2) save that block into a file on your hard disk using one call to the TOS function Fwrite() (preceded, of course, by Fopen, etc). 3) (later, outside that program:) run ARC on that file to compress it, and upload. (The 360K should be compressed down to 180K or better.) Optimization: write the files to a freshly formatted floppy, to make sure the files are not fragmented and there are no "holes". Then make the program find out which is the last data sector actually used on the floppy, and only copy up to that sector. You can find code to do that in my program FLEXCOPY. Note: to make sure everybody can get it and like it, use a STANDARD TOS formatted floppy disk to start with. Also you may want to use a single-sided floppy since some poor souls out there are still stuck with those obsolete SS drives :-) - Moshe Braner

I wrote a Program called "darc" which uses arc to recursively collect a whole folder tree into a single file and unarc it again to restore the tree. You can found it at the Atarinet- Server in Houston (Bitnet). If this doesn't work I can mail it on request or post it to the binaries group. G. Teege

I think that the "tar" utility posted to the binaries recently will archive subdirectories, etc. (at least the Unix version does) then you can compress the archive file using arc, compress, etc. The ZOO archiver (available for PC, Unix, and Amiga so far) would be ideal, as it can handle directories, but I have yet to see a full archiver come across the net. There was a BOOZ (zoo file extracter only) utility, however. Hope this helps. Johnie Wardlaw

Sorry about that, Mike. I should have made that clear. The program that compresses an entire disk is Magic Shadow Archiver R1.03. Shadow from Double Click is an entirely different beast. Lawrence Y. Chiu; University of California, Berkeley.

there are two public domain program to archive complete disks (including folders and subfolders). One is called CRUNCH or SCRUNCH and the other is called the Magic Shadow Archiver. CRUNCH came out first but its main hadicap is that you have to preformat the destination floppy with the correct format of the original floppy BEFORE running CRUNCH. And there is no way to know what the original floppy's format was except trail and error. Magic Shadow Archiver produces an output file with 'MSA' as the filetype. And MSA will correctly format the destination floppy as the 'MSA' file contains that information. I am not sure if thes programs are on GEnie, as they are public domain you shouldn't have any problem locating them. Good luck!!! Richard Covert

I got several requests for my "darc"-program that I mentioned in my last article. So I just posted it to the binaries group. I hope it will show up soon. G. Teege
teege@lan.informatik.tu-muenchen.dbp.de (Gunnar Teege) (12/14/88)
Sorry, I promised to post the program DARC (for arc'ing whole folder trees) to the binaries group, but Steve told me, that it was there already! (it did not reach our node then, so I thought it got lost). So please look in an archive for the binaries group for the program. If you can't get it this way and absolutely want to have it, mail to me and I will send it per mail. (Warning: the program is SLOW, because it simply arc's the folders recursively. It does not store boot sectors or other copy protection gimmicks, but only normal folders, subfolders and so on. But it works on all devices and on arbitraryly deep nested subfolders.) G. Teege

The magic shadow archiver is available for anonymous ftp from PC7. It is called shadow.arc. The index is still very much outdated, but steps are being taken to rectify the situation. Jon Brode -- dyer@math.lsa.umich.edu PC7 moderator, Atari God

There are more ways to compress a whole disk !
One is darc.ttp which invokes arc.ttp for each subdirectory rekursively.
Another one is FOLDER.PRG (also called AR.PRG).
It compresses a whole path including all subdirectories !
As far as I can remember by heart it is written by somebody at the Tech. Univ.
of Berlin...
It's seems not to be known widely, although I saw it quite often in BBSs here
in Berlin.
If some Bitnet-User sends me his mail-address I'll send a copy of it, so you
can get your own impression of it. I'm not mailing it outside the bitnet,
because that would mean to spend a lot of money (0.60 DM/KB via Pyramid or
1.10 DM/KB via unido !) I do not have.
Please reply using the bitnet (ripley%netmbx.uucp@db0tui6.bitnet), I have to
pay incoming data as well !
