- - 7zip Question (http://www.abandonia.com/vbullet/showthread.php?t=9761)

Hey guys, quick question. I have a 7zip file (*.7z) and I know how to extract it. Both 7Zip and WinRAR (though 7Zip works better, obviously) can extract .7z files. However I cannot seem to figure something out.

My friend has a bunch of e-books that he wanted to send to me. For simplicity and neatness, he zipped them all together in 7zip format. I can unzip them all easily enough, but there are hundreds of e-books this dude has! I don't wanna unzip ALL of them, just a few choice ones. I can't manage to do that though. In both WinRAR and 7Zip, any option to extract them, no matter if I highlight 1, all, none, right-click 1 and tell it to extract to spesific, no matter what I do, both programs start extracting ALL of them into the spesified folder.

Is there a way to extract single, spesifc files from a .7z and not the entire thing? Thats easily done in .zip and .rar files, but it just dosen't wanna work in .7z for me. o.O

7z x archive.7z filename_of_file_you_want_extracted

:P Little more Layman's terms if you please? Not all of us are that computer savvy :D if it helps, i'm using Win2k.

I think Data means you have to use command line for that purpose.

In 7ZIP GUI manager select multiple files you like to extract by holding CTRL key while selecting. Selected files should change background color and when you press extract, only those files will extract.

These are not exactly eBooks. LOL

What OS and what 7-zip version do you have?

It should change background color for complete line, not only for file name.

Shhh :P They're e-books as far as i'm concerned.

OS is Windows2k, (Don't mind the color, I just saved them as very low-rez .gifs to save time uploading them.) and 7-zip is version 4.32.

Dunno why it only highlights a little bit, but it does.

:) guis :)
in the end they are only limiting the flexibility of the tools.

Couldn't agree more, but in some cases it saves a lot of time.

@ MrBackAlleySka - something is wrong with your 7Zip installation (not sure if archive might be wrong)

When you select those, you press Extract? Try right click one of them and select 'copy to'.

Extract begins extracting all, just like the screenshots say, and the "move to" and "copy to" commands both start moving/copying the entire archive to the spesified place.

=/ Im going to delete 7zip completely, and grab another, older version, see how that goes.

Good idea! :)

Let us know!

Well im beginning to think it's the archive, and not 7Zip, cause redownloading and trying both the same version again, and a diffrent version again, does the same thing. Odd though that they aren't highlighting the full line like in your screenshot. Ohwell Heh

Do following:

Create 7Zip archive from some folder you have.

Try to extract 1 or 2 files out of that archive to temp folder.

If it works, you have your answer. :D

Or email eBooks to other good readers (like my self) :whistle: :tomato:

Even I'm sure I have more then once every single book in your complet. LOL

To answer the question in the third post, that would be the command to do it in Linux I believe.

ZipGenius does the trick for me. If you keep having problems with 7-Zip, maybe you could try that?

It is the same (or very close) on the window.

Data,
how to zip one folder with a lot of files (backup files)?

@Beef
Yeps you are right. but I assumend the basic options would be the same between the different OS-es

@Anubis
depends wether you want recursion or not
without:

Code:

7z a result.7z directoryname

with

Code:

7z a -r result.7z direcotryname

offcourse you can specify -m parameter to improve compression

here are some useful options

Code:

7-Zip 4.33 beta *Copyright (c) 1999-2006 Igor Pavlov *2006-02-05

p7zip Version 4.33 (locale=C,Utf16=off,HugeFiles=on)

 *

Usage: 7z <command> [<switches>...] <archive_name> [<file_names>...]

 * * * [<@listfiles...>]

 *

<Commands>

 *a: Add files to archive

 *d: Delete files from archive

 *e: Extract files from archive (without using directory names)

 *l: List contents of archive

 *t: Test integrity of archive

 *u: Update files to archive

 *x: eXtract files with full paths

<Switches>

 *-ai[r[-|0]]{@listfile|!wildcard}: Include archives

 *-ax[r[-|0]]{@listfile|!wildcard}: eXclude archives

 *-bd: Disable percentage indicator

 *-i[r[-|0]]{@listfile|!wildcard}: Include filenames

 *-l: don't store symlinks; store the files/directories they point to

 *CAUTION : the scanning stage can never end because of symlinks like '..'

 * * * * * *(ex: *ln -s .. ldir)

 *-m{Parameters}: set compression Method (see the manual)

 *-o{Directory}: set Output directory

 *-p{Password}: set Password

 *-r[-|0]: Recurse subdirectories

 *-si[{name}]: read data from stdin

 *-so: write data to stdout (eg: % 7z a dummy -tgzip Doc.txt > archive.gz)

 *-t{Type}: Set type of archive

 *-v{Size}[b|k|m|g]: Create volumes

 *-u[-][p#][q#][r#][x#][y#][z#][!newArchiveName]: Update options

 *-w[path]: assign Work directory. Empty path means a temporary directory

 *-x[r[-|0]]]{@listfile|!wildcard}: eXclude filenames

 *-y: assume Yes on all queries

It's normal the archive <strike>must be</strike> IS a solid one (all the files are compresseds as a single big file) it's a technic that help to reduce size even more (drasticly on files with very fews differences like, for EXAMPLE; roms of diferents regions or languages....)
But the conterpart il that when you want one specific file it have to uncompress every file that been interlaced with the one you want.
In the end you'll only get the files you asked for.
