PAKKA (ZPAQ's Win32 "versioned" unpacker)

[fcorbelli]

http://www.francocorbelli.it/pakka/

This program is designed to easily extract different versions of files compressed in ZPAQ on Windows platform,
something like zfs' snapshot.

The main actors are the various versions of the files, never overwrite file (append _xxxxxxx);
show (ugly) estimated ETA.

I use it mainly with huge mysql dumps and source code.

---
Can be used from the command line: pakka filename.zpaq
Pakka ? for CLI help.
/noskin to turn off skin color (automatically disabled when is in Terminal mode).

No need for zpaq.exe (will be extracted in %temp%).

Can stop extraction via Control-C (in the ZPAQ window), or clicking Exit
(or closing the main Window).

---
You can use this program in any way you want, but without any warranty,
at your own risk.
---
Remember: ZPAQ is a Matt Mahoney's (great) program
http://mattmahoney.net/dc/zpaq.html


Currently without KEY (crypto) support, and with 6.43 version instead of 6.44

Please be free to suggest improvements

Since you mentioned zfs snapshot, a GUI like the Time - Slider on OpenSolaris/OpenIndiana will be really great addition:

Hi,

hm its seems that now everyone including me is developing a zpaq gui. =D

I'll think about something more... user-friendly

I need a convenient way to extract the files.
ZPAQ is great in everything, except that in this case,
and really needs a ETA for extracting multigigabyte \ versioned file.

I don't need a "compression" GUI (100% batch-crontab), and PAKKA is an integrated part (a Delphi form) of my ERP software, running mysql dump (mariadb) backups

yeah i can fully understand you., thanks for the ETA idea =D

Complimenti bel lavoro!

Good work , nice!

[fcorbelli]

Thanks, I'm currently working on a better (and faster) tree creation, currently very slow (and sometimes crash) for >60.000 files.

Ciao Francesco!

[fcorbelli]

Update: build 5, with ZPAQ 6.45, cripto password support (command line & gui), and MUCH faster tree generator.
Needs a smarter (faster) decoder for version file, currently on my PC 6 seconds for 200.000 files (300s for build 4).

Please, add *.zpaq filter while opening.

Done
Build 6 introduce filtering of filenames


Much faster with a zillion file.

Using =something search exact file name.
Empty string => show all tree

I often recieve an error that "Extracted file is incomplete" while they really complete and good extracted. Can you localize the issue by yourself?

Yes, this is a test of the filesize after extracting

 if gf_selectedFileSize<>prendidimensionefile(gf_myto) then ...

I will add an explain of expected filesize, and currently one.
Maybe a bug in selecting right file size? I'll check.

I use when blocking zpaq before end of extract (for very big file can take hours) via Control-C.

Release build 007 that

1) hide (or show) empty dirs (via checkbox). Default: hide
2) remember the last directory where extract file
3) show the selected file size in label (for debug)
4) show more infos when extracted file size does not match
5) update only on mod 10 when analyzing
6) does not popup when select an empty file
7) when extracting with keyboard if you press ESC does not execute
include a CATCH for (maybe) the above problem with a debug message

In build 8 I have implemented a time machine-like slider.

Select version => click => get the files at this moment (maybe, if you're lucky )

The leftmost position regenerate "versioned" tree.

Currently not tested, and not developed very much, but comfortable.

In future Explorer-like icons.
But I'm not sure, because needs a lot of resource (and time) only for cosmetic.
Not so good for >1M files

[fcorbelli]

Build 9.

- Now recognize encrypted files (... I hope!), asking password if needed.
- Embedded ZPAQ 6.49 released

"Time machine", despite of a known (and wanted) bug, seems to work well, but not deeply tested.

www.francocorbelli.it/pakka/pakka.exe
www.francocorbelli.it/pakka/pakka010.zip

Build 10.
Added support for extracting in Windows of FreeBSD's archive

[fcorbelli]

www.francocorbelli.it/pakka/pakka.exe

This beta version can extract (maybe!) selected files "alla database".

Not tested to extract linux files on windows machines (next version)

Future release: extract all different versions of selected file,
fix root-node

zpaq v7.00 and later will extract all versions using -all option. They will be placed in directories 0001, 0002, etc. For example, c:/foo/bar will go in 0001\c\foo\bar

i konow, this was my suggest.
but i should rewrite the parser for v7 and i do not have time, currently.
my top todolist for pakka is notes, and i think i will chain rar with zpaq

what features did your own zpaq include?
And could you make it available for everyone?

I'm sorry I have read only today.
I use a standard (but ancient) zpaq.exe linked as resource to my software, extracted on temp directory before run.

np i found a solution for my problem. =D
