Hi there, Just wanted to let you guys know that there's a new version of ARJ that's out. Version 2 is *supposed* to compress as well as LHA 2.1x (gives perhaps the best compression around) AND is supposed to compress as fast as PKZIP! If any of you know an ftp site where it can be found, please mention it. I got my copy of ARJ 2.0 from Delphi. As usual, I haven't had time to test ARJ, so correct me if I'm wrong... But that's what I read in the .doc file. Cheers, Kevin

But >that's what I read in the .doc file. ARJ 2.00 is available on simtel under pd1:<msdos.arc-lbr>arj200.exe. I ran some crude tests using 11 binary files and 11 text files. Here are my results. All times in seconds of course ;-) Binary data - 11 misc. EXE files (358,783 bytes). Compression time Compressed size Decompression time LHa 2.12 1:44.89 244,226 42.74 ARJ 2.00 1:27.74 243,498 44.50 PKZIP 1.1 1:00.05 251,433 22.25 Text data - 11 misc straight ASCII files (247,669 bytes). Compression time Compressed size Decompression time LHa 2.12 1:15.98 88,193 24.12 ARJ 2.00 1:00.54 85,859 26.37 PKZIP 1.1 48.84 92,057 17.91 Considering ARJ 1.10 sucked (flames >/dev/null), this is a tremendous improvement. Phil Katz is the only one that hasn't released a new version of ZIP, but I'm sure that's in the works. -- +==========================================================================+ | Noam Mendelson ..!ucbvax!web!c60b-1eq | "I haven't lost my mind, | | c60b-1eq@web.Berkeley.EDU | it's backed up on tape | | University of California at Berkeley | somewhere." |

Ours are in the /pc/arcers directory. Arj's file name is arj200.exe. While we are at it. Are you aware of the archie service for finding the ftp locations of files. If not, you can (among other sources) find the necessary pointers in /pc/ts/tsfa19b.arc Frequently Asked Questions collection. (Archie is very handy, the only problem being the time lag.) If you don't know how to go about getting files from garbo.uwasa.fi, you are welcome to email me for the prerecorded instructions. ...................................................................

But >that's what I read in the .doc file. As usual, the speed claims are exagerated, but it is an impressive improvement. ARJ 2.0 blows LHarc 2.12 out of the water. It packs about the same, and is much faster (hope that's not too technical). It is still slower than PKZIP, but he's really speeded it up. Instead of taking 2-3 times as long as the ZIP version, it takes about a minute longer than ZIP does to compress a file that takes ZIP 3 minutes. Really vague, I know. I've got all the results at home, I'll bring them in and type them up.
