DavidMil Posted November 4, 2018 Share Posted November 4, 2018 I downloaded a couple of arc files, but I don't have any way to look at them. I went out on the web and every site wants to put all kinds of CRAP on you PC before you can download anything. Does someone have the app that I can get a copy of, or know of a place I can get a copy without having to agree to all kinds of crap? Thanks, David Quote Link to comment Share on other sites More sharing options...
Nezgar Posted November 4, 2018 Share Posted November 4, 2018 I had the same issue, and found IZarc for windows: https://www.izarc.org It supports a lot of older formats including ARC, LHA, LZH, ARJ, and newer stuff. Quote Link to comment Share on other sites More sharing options...
Mathy Posted November 4, 2018 Share Posted November 4, 2018 Hello guys Try SuperUnArc by Bob Puff. You can find it at my Special Stuff Page. Sincerely Mathy Quote Link to comment Share on other sites More sharing options...

AtariGeezer Posted November 4, 2018 Share Posted November 4, 2018 Or, you can load them in Altirra and save it as an ATR 2 Quote Link to comment Share on other sites More sharing options...

Just to add... IZarc appears that it can decompress from ARC, but can't compress to ARC. Quote Link to comment Share on other sites More sharing options...

Kyle22 Posted November 5, 2018 Share Posted November 5, 2018 I save the ARC file on a PCLink share then (in SDX) type ARC X (filename). very easy. Quote Link to comment Share on other sites More sharing options...
fujidude Posted November 6, 2018 Share Posted November 6, 2018 Peazip has an ARC capability, but I don't remember if handles .ARCs in the old format that Atari ARC utilities use. I've been using Linux for a wghile now, and just use the ARC command available for Linux by Howardd Chu. Quote Link to comment Share on other sites More sharing options...
_The Doctor__ Posted November 6, 2018 Share Posted November 6, 2018 On the Arc, like everything else it's good to have two of everything... two ARCS are better than one! (I know I know, I just couldn't resist) 1 Quote Link to comment Share on other sites More sharing options...

Mclaneinc Posted November 6, 2018 Share Posted November 6, 2018 izarc is nice but it won't work with all atari arc files, throws up an error sometimes.. Nice for what it does tho.. Quote Link to comment Share on other sites More sharing options...
Mclaneinc Posted November 6, 2018 Share Posted November 6, 2018 Or, you can load them in Altirra and save it as an ATR How are you doing that exactly...Just for info.....I can't think of a way to do it but I wonder if you have found an easier way Quote Link to comment Share on other sites More sharing options...
_The Doctor__ Posted November 6, 2018 Share Posted November 6, 2018 update your izarc... it helps... but we run into that sort of thing enough that I included a bunch of ways to get it done on esp. on the Atari itself... Quote Link to comment Share on other sites More sharing options...
Nezgar Posted November 6, 2018 Share Posted November 6, 2018 How are you doing that exactly...Just for info.....I can't think of a way to do it but I wonder if you have found an easier way For any mounted ATR there's a disk explorer option where you can drag files in/out of the disk image. So you'd drag the ARC file into the ATR - do the unarc from an Atari program running inside Altirra, then if you need the unarced files on the PC side, just drag the resulting files out of the disk image after. Same process is possible using AspeQt/RespeQt, just a real Atari doing the ARC processing. With Altira, I guess you could just map a windows directory to H: and operate directly on the PC file bypassing using an ATR. With RespeQt you can read/write files directly in a PC folder from a real Atari with SpartaDOS X & PCLINK.SYS while maintaining date/time stamps too. AspeQt and RespeQt also support a simpler live disk image 'simulation' in AtariDOS format from a PC folder. More limited and no time/date sync, but compatible with more DOS's.

Kyle22 Posted November 7, 2018 Share Posted November 7, 2018 That's nice, but I still find it easier to use SDX. Quote Link to comment Share on other sites More sharing options...
1050 Posted November 7, 2018 Share Posted November 7, 2018 While I prefer MS-DOS on win98 using the original System Enhancement Associates ARC 5.0 which is exactly what Puff's SuperARC and SuperUNARC are based on. But caution is advised - this is the very program that would hound Phil Katz to his untimely end and very first flame war to end all flame wars. Posting it would then be against copyright law even if no-one cares anymore. I used to post a link to it but the University of Texas apparently had better use of the server space that used to host it. It's gone now. But the curse lives on: "If you fail to abide by the terms of this license, then your conscience will haunt you for the rest of your life." It will do both ways perfect every time, but you missed your chance unless you can find it on your own now. 1 Quote Link to comment Share on other sites More sharing options...
Nezgar Posted November 7, 2018 Share Posted November 7, 2018 Yeesh, I didn't know about that nasty history.. (good write-up on Wikipedia) Explains the downfall of ARC, and the rise of ZIP ! Author of ARC withdrew from software development due to the barrage of hate mail, and author of PK Zip died in 2000 at age 37... How tragic. And I read mentions previously of some ARC files being incompatible, this from the FAQ: https://www.atariarchives.org/cfn/12/02/0094.php- "Super Arc uses 3 of the 5 total types of compression: Storing, Packing, and Crunching, which is the method most often used." - What were the other 2 methods? Edit: Answered my own question! - from http://apple2.org.za/gswv/a2zine/GS.WorldView/Resources/The.MacShrinkIt.Project/ARCHIVES.TXT : COMPRESSION METHOD ------------------ NAME METHOD DESCRIPTION ----------- ------ -------------------------------------------- Stored 0 No compression used Packed 1 Repeated running length encoding (RLE) Squeezed 2 Huffman encoding Crunched 3 LZW with 4K buffer, 12 bits codes Crunched 4 First packing, then LZW 4K buffer with 12 bits Crunched 5 Packing, LZW, 4K buffer, vari len (9-12 bits) Squashed 6 LZW, 8K buffer, variable length (9-13 bits) Crushed 7 Packing, then LZW 8K buffer, 2-13 bits (PAK 1.0) Distill 8 Dynamic Huffman with 8K buffer (PAK 2.0) So SuperArc supports 0, 1, not sure about 3, and one or more variants of crunch, 3, 4 or 5... PAK mathods 6,7,8 were from later PK era, so understandable not supported. I found these working links to download the latest SEA & PK ARC programs for MS-DOS: (As 16-bit executables, they don't work in Windows 64-bit - maybe they'll run with DOSBox.. or a VM)This site has some of the original DOS programs: http://sta.c64.org/dosprg.htmlPKARC 3.5 (1987-04-27), archiver that handles ARC archives (© by PKWARE Inc., 1986-1987) [pkarc35.zip, 65.144 bytes]PKPAK 3.61 (1988-08-02), archiver that handles PAK archives (© by PKWARE Inc., 1986-1988) [pk361.zip, 113.209 bytes]ARCView 7.1 (1995-06-21) , lists and extracts files in various archive formats interactively(© by Sergey Nazarenko, 1990-1995) [arcv_7_1.zip, 89.179 bytes] And: http://archives.thebbs.org/ra31c.htmARC602.EXE 135K 10-03-1988 ARC version 6.02 by System Enhancement Associates.

Mclaneinc Posted November 7, 2018 Share Posted November 7, 2018 (edited) Thanks guys, its the methods I use, wondered if I'd missed something you devils had found out Slight word re the booting arc files, yes it works if its in a dos files format ie has dos files in it otherwise it treats it as a non dos disk.. I try and avoid lots of typing if I can do something another way just to be easy on the fingers and the arthritis, that's why I don't talk about the Superun.com etc, to be honest I set up my PC Directory opus so selected files and programs can work together from a single click with anything I can....(That's PC programs in general) Edited November 7, 2018 by Mclaneinc Quote Link to comment Share on other sites More sharing options...
fujidude Posted November 7, 2018 Share Posted November 7, 2018 Okay I remember now what I used to use on Windows to deal with ARC files; specifically older style ARC files like are used with Atari 8-bit computers. See this post on AA from some time ago for more detail. The program is called Universal Extractor and you can get it here. 2 Quote Link to comment Share on other sites More sharing options...
+Larry Posted November 8, 2018 Share Posted November 8, 2018 I've run into this same issue a few times. 95% of the time AlZip (was freeware) works just fine, but every so often, I'll d/l an ARC file that gives me a "corrupted" error message, and I'm usually quite sure that the ARC is not corrupted. So I have to go to Puff's Super UnArc. Very slow, but sure. Thanks, I'll try this Universal Extractor. Edit: See Wikipedia for AlZip history.

Atari_Ace Posted November 9, 2018 Share Posted November 9, 2018 To add to the options, when I was facing a similar problem a few years back, I found the CLI tool nomarch at http://www.svgalib.org/rus/nomarch.html. I believe I had to compile it myself for Windows, so I've attached my copy. nomarch14.zip 1 Quote Link to comment Share on other sites More sharing options...
