7-Zip
As far as I can tell from doing a few experiments with 7-Zip, reading the documentation that comes with it, and browsing a few pages of the 7-Zip Support forum at SourceForge, 7-Zip entirely lacks an absolutely basic feature of WinZip, which is essential for saving and restoring complex structures of files and directories (folders): namely, that you can add to a specified archive any specified set of files together with all its path information. This seems especially odd, as 7-Zip is perfectly capable of understanding the directory structure of an archive created by WinZip. It displays the information differently: whereas WinZip shows the path information in a column headed "Path", 7-Zip shows directories as icons in its own window, and gives a "flat" display of all the files and directories in any directory you select, thus behaving rather like a version of Windows Explorer (and indeed it is described as a "File Manager", rather than a compression and archiving utility). I know I'm inclined to give up too easily, so am I missing something here? Is it a question of reading more carefully through all the documentation on the command-line version of the program, with all its interacting options? -- Angus Rodgers |

: As far as I can tell from doing a few experiments with 7-Zip, SNIP Without reading all of that (I am NFG in the mornings either, in fact I use coffee and the Usenet to wake up), I tried it. I just zipped 3MB's of stuff (3 dirs), took about 1.5 seconds, unzipped into 3 separate dirs in about 2 seconds. Also, there are 30 other free or free trial zip programs you can use instead of 7-zip. Google "free compression program". Why are you afraid of a totally harmless program? Just do SOMETHING. And never mind the **** left behind by WinZip. It'll just sit there. Also, as a comment on your other post, the name of practically every uniquely weird file that SOME program uses has been adapted as a Trojan or virus container precisely because few people ever notice them.

I thought I just had. I re-read through that entire long WinZip thread, and compiled a list of every single suggestion made. I uninstalled Spybot. (No problems there.) I installed 7-Zip. I created several of my usual backup archives using 7-Zip, copied them over the LAN in the normal way, and opened them with WinZip on the other PC. No path data! Here's an experiment. Consider the following structure of files and directories [folders - I prefer 'directories' myself, as do you, but, in a Windows context, it often seems less fussy to use the Windows term], which you can easily reproduce on your system: A a directory (at partition root level, say) x.txt an arbitrary file in A B a subdirectory of A y.txt an arbitrary file in B Go into A, and "add" file x to an archive, located somewhere or other. (I don't know if there is a convenient way to tell 7-Zip to make its archives in some preferred location. With WinZip, I used to create an empty archive, where I wanted it, and add files to it incrementally. There is nothing odd about the idea of an empty archive, or empty container of any kind. Boundary cases should be handled in a regular manner. This is a common wisdom in both mathematics and computer science, e.g. when de- bugging programs. Mathematics is full of empty or null objects such as zero, and programs are full of loops which sometimes are executed zero times. Text files containing no characters exist as proper files. And so on.) Now go into B, and "add" y to the same archive. Does path data for x and y not get lost? What am I doing wrong? With WinZip, you could move around in the file system and add data incrementally to an archive, like this, and path information would be preserved. It is part of my normal backup procedure, and I would be lost with a program that does not do this. And never mind the **** left behind by WinZip. It'll just sit there. I expect so. One thing at a time. Amen. -- Angus Rodgers |

Not sure about 7zip, since I gave up on it in one of its early offerings due to some issues involved. Though what you describe was due to requests by 7zip users IIRC. That type of display is also used in WInRAR and several others. I have to question why you don't/shouldn't use pkzip, ARC, LHA, ARJ, RAR, Scrunch, Squeeze, U2, zoo, or one of the other older DOS based compression archive programs. Newer versions [some] of those supported long file names, *archival bits* [refresh if modified, add if new], directory preservation, and other functions. You apparently aren't creating these for use elsewhere [posting, ftp, etc.], so your concern is local support and merely backups of files. These would be/have been perfect for batch file usage, that is, unless you need a graphical interface for some reason. Then again, there were Windows or DOS GUI interface applications for those DOS tools [like Shez]. -- MEB http://peoplescounsel.org/ref/windows-main.htm Windows Info, Diagnostics, Security, Networking http://peoplescounsel.org The "real world" of Law, Justice, and Government ___--- |

Yeah, that's what we used to do before "backup" programs and GUI became so important. If you do it, make two sets, one updated daily or whatever, and the other bi-daily, bi-weekly, or whatever suits your purpose. Saves losing anything except beyond whatever the second longer time-frame set holds. Or do one for even days, one for odd, or similar. -- MEB http://peoplescounsel.org/ref/windows-main.htm Windows Info, Diagnostics, Security, Networking http://peoplescounsel.org The "real world" of Law, Justice, and Government ___--- |
