And 7-zip have no instruction in the basic principles to use the program. Though it seems to work very different to main stream programs like winzip, winrar, and winace. A wiki is badly needed. But then of course, things has to work in the program.

This seems to be a program for commandline experts, and for people that has focus on the compressing quality. I you have focus on smooth workprocesses, dont use this. Fom its windows utilities, you can not add files to existing archives. You can not change files in an existing archive. You can not drag and drop files into existing archives in the double panel. In order to change an existing archive you have to unpack all the files, make the changes, and then create a new archive. Even old commandline programs had better functionality 15 years ago.

I used both programs, winrar and 7zip. 7zip seems much more “complete” to me.

When is the “not implemented” bug (when trying to delete from solid archives) due to be fixed?

7Zip 4.65 has great potential and already provides some useful features.

However, it still falls short of other archiving applications in easy to use, basic features, such as adding and extracting to archives with full path structures. Sorry, but command line cd /D c: blah, blah… and UI “parameter” box kludges don’t cut it.

Did you by any chance create a *solid* 7z archive? (You can check this by looking at the “solid block size” parameter in the “Add to archive” windows).

According to the help file, 7-zip is currently unable to modify the contents of solid 7z archives. “Non-solid” archives work fine though…

Let me know if this helps.

oops, I obviously have 2 left feet instead of two hands…
I was saying with latest version to date 4.64 I am unable to delete files from a 7Zip archive inside subdirectories (2 levels).
deleteion and update of existing files work with flat archives (no dir at all) or 1 level of directory, but it answers me “not implemented” (well actually “non implémenté” as it is in French) when having 2 directories.
Example:
Desktop – file p05.jpg –> P05.7Z (maximum or ultra w/ lzma) : I can update or delete file p08.jpg inside the archive
Desktop – dir “New folder” w/ p05.jpg inside –(added to)–> Desktop\P05.7Z : it works fine, the same as above : update/delete
Desktop – dir “New folder” w/ “Folder2″ inside w/ p05.jpg inside –> P05.7Z : I can add but cannot delete any more a file in that dir nor update it. (NB: I can still rename the file at the deepest dir level but can’t delete it any more)
I can still update or delete the file at the above directory level.

Questions : 1. bug or feature ? 2. If bug, will it be fixed soon ?

Thank you all for your answers.

Hello,

Happy new year to all the forum members.

I have a small question about 7Zip (latest toda4.64

I guess that, since 2006, Igor found the time to fix the empty dirs thing

BTW, 4.42 is kinda old already, why not upgrade to 4.64?
