WINZIP VS 7ZIP ARCHIVE
The result was about 20% smaller than building a deflated archive with PKZIP in a single step (yes, I had tried it), just enough to save a second 1.44MB diskette in each copy of the book. In Step 2 the single file from step 1 was compressed using PKZIP's maximum compression (deflating). In step 1 an uncompressed archive of all files included was built, using PKZIP. The concept was used about 20 years ago in distributing the files that were bundled with a software book (IIRC Plaguer's The Standard C Library) on a single 3.5in diskette instead of two diskettes, by a two-step process. The extra processing required makes it slower, but improves the compression ratio for the while archive. This allows the use of a single compression table which is optimized for the whole set. One of the major concepts of 7Zip is to compress all files that form the archive (at least when it is first created) as a single task. Much more important is the information included in an archive's Table of Contents allowing copy verification and attribute preservation (directory hierarchy, protection and age attribute preservation. Minor improvement of compression efficiency is hardly ever significant, unless it happens to be cross the limit if what fits on a single volume of the distribution medium. IMHO today compression is only relevant for backups (unless you have slow internet, or its cost is based on volume). I have no quibble with the efficiency of the internal ZIP command. Much as I appreciate Perl: That documentation ain't so great, either. Then again, ActivePerl comes with ZIP support. I really did like his ARJ program, and its (almost uknown) big brother, JAR (not related to Java). Too bad the ARJ guy seems to have given up on 64-bit. It's kind of irksome that after all these years they still split that whole business into WZZIP and WZUNIP (or did the last time I used the program), but oh well. There's a simple "f" switch, as I recall, for their WZZIP tool. The Winzip people keep badgering me in e-mail to upgrade. Maybe there's a simpler way, but damned if I could find it.Īctually, there is a simpler way. But if I didn't use ALL of them, it didn't work - I would have to specify the filenames to be "freshened" (exactly what I didn't want). After poring over the help file for quite a while I thought I could get it done by omitting at least a few of those arguments. The help-file for that program is not, how-do-you-say, sterling. The 'u' command followed by this switch+argument combination: This is kind of grim but I think I found what I needed for "freshen" in 7zip: "C:\Program Files\7-Zip\7z.exe" a ZIPs\7Zip all.txtĮcho PKZIPc version is Files (x86)\PKWARE\PKZIPC\pkzipc.exe"] Registered to Charles S Galloway - 5 System License TCC Build 56 Windows 7 Build 7601 Service Pack 1 Portions copyright (C) 1989-2011 PKWARE, Inc.
