UHARC - how to skutecznie


(KaiES vel Sikorsky) #1

Może znajdzie sie ktoś kto mi wytłumaczy jak skutecznie kompresować programem WinUHA lub UHARC GUI 2.0. Ja po paru probach osiągnąłem oszałamiajacą wysokość kompresji - aż 1 mb mniej :lol:

Z doświadczenia wiem, że ten program potrafi naprawde dobrze kompresować - niekiedy spotykałem się z prawie 10 krotna kompresją - z folderu o objętości 970 mb robiło się 120 mb

Jest ktoś chętny??

gretzz :?

no no… co Was tak tu pełno :twisted:

Znalazłem przewodnik po tym programie. tylko, że w języku angielskim. Radzę sobie z tym jezykiem całkiem dobrze. Ale jakby ktoś mial niepochamowana cheć przetłumaczenia tekstu będe wdzięczny ( tylko mi nie tlumaczyć tego English translatorem - mydła z powidła to ja nie chcę)

Jak się uporam z pomalowaniem łazienki to sam się chyba wezmę za tłumaczenie tego z nudów.

pozdrawiam :shock:

UHARC 0.4 Compressing Guide 


UHARC is one of the best archivers ever made. Really. The compression result is usually far better than any other archiver. According to my experience, the archive file size is (average) 10% smaller than one compressed with RAR3-format. As there are many people out there with no idea how to use this command prompt-archiver, I decided to give you a tiny, but comprehensive guide.


This instruction applies to UHARC 0.4, get it here.. To make the usage easy, save it to your /system32 -folder.



Usage: UHARC command [-switches..] archive[.uha] [filespec..@listfile..]


Commands:

~~~~~~~~~

a Create archive/Add files e Extract files to current dir

m Create archive/Move files x Extract files with full path

l List files in archive t Test files in archive


Switches:

~~~~~~~~~

b Set max buffer size o[-,+,p] Set overwrite mode

d<0..2> Set display mode p<-,r,f> Set path mode

lg Log output r[-,+] Recurse subdirectories

m<0..3> Set compression mode t

Set extract target dir

md Set dictionary size y[-,+] Set auto-answer mode

md[-,+] Disable/enable dictionary-based compression

mm[-,+] Disable/enable built-in multimedia detection/compression



* For commandline help type "UHARC" without any parameter.


* The command character must be placed immediately after "UHARC".


* The switches, if any, must follow the command character. UHARC supports

the use of either "-" or "/" as the switch option character.


* The UHARC archive name must be the first filename on the commandline.

If there is no archive file extension specified, UHARC will add the

default (".UHA") extension.


* After the archive filename come the list of files for the given

operation. One or more files containing a list of files to process

can also be used by prefixing the list's filename with "@". It's

possible to mix filenames and list files in any order. Allowed

delimiters for filenames in list files are space, tab and newline.


* Filename wildcards are allowed in commandline and in list files,

but not for archive filename. The use of wildcards follow MS-DOS

convention. "*.*" means all files. "*.txt" means all files with an

extension of ".TXT". "?B*.*" means all files with a second character

of "B".


* If there are no files specified at all, all files ("*.*") will be

processed (use "-r" to recurse subdirectories).



Commands and Switches



a Create archive and add matching files.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

If a file with the archive name already exists, UHARC will ask

before overwriting this file, unless you change the default

overwrite mode or use "-y".


Following switches have effect: -b -d -lg -m -md -mm -o -p -r -y



e Extract matching files to current directory.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Stored pathnames will be ignored. Using the switch "-t", you can

change the current directory for extracting.


Following switches have effect: -b -d -lg -o -t -y



l List matching files in archive.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Using switch "-y", UHARC will not pause after one page, else you

can use the following keys:

ESCAPE = Cancel (quit program)

TAB = Disable pause

RETURN = Next line

other keys = Next page


Using switch "-d2", filenames are not shortened and more

information are displayed.


Following switches have effect: -b -d -lg -y



m Create archive and move matching files.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

If a file with the archive name already exists, UHARC will ask

before overwriting this file, unless you change the default

overwrite mode or use "-y". If compression was successful, UHARC

will delete matching files on disk (but no directories).


Following switches have effect: -b -d -lg -m -md -mm -o -p -r -y



t Test integrity of ALL files in archive.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Following switches have effect: -b -d -lg -y



x Extract matching files with full pathnames.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

UHARC will use the pathnames stored in archive for extraction (if

the archive was created with option "-pf", this also includes drive

letters). Using the switch "-t", you can select the root-directory

for all extracted dirs/files.


Following switches have effect: -b -d -lg -o -t -y



Note: During all operations it's possible to terminate the process

by pressing ESCAPE and answering the following question with

"Y" (when listing files, there is no additional query).





-b Set maximum file buffer size (in KB ).

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

After allocating all structures for (de)compression the

remaining memory is used for file buffers, but never more

than . The minimum buffer size is 50 KB.


DEFAULT: -b2048



-d<0..2> Set display mode.

~~~~~~~~~~~~~~~~~

-d0 Quiet mode (no process information, except queries).

-d1 Display some process information.

-d2 Show more information (file info, verbose listing).


DEFAULT: -d1



-lg Log UHARC output to specified .

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

If UHARC fails to open , no log is created (without an

error message). The display mode setting has effect on log,

too.


DEFAULT: no log file



-m<0..3> Set compression mode.

~~~~~~~~~~~~~~~~~~~~~

-m0 Store files without compression.

-m1 Use FAST compression mode.

-m2 Use NORM compression mode.

-m3 Use BEST compression mode.


Mode "-m1" is the fastest mode, sacrificing compression ratio

to gain better speed. Mode "-m3" achieves best compression and

needs most time. Mode "-m2" is nearly as good as BEST mode,

while running at higher speed (best compromise ratio/speed).

The decompression speed is nearly the same for FAST/NORM/BEST

modes and is much faster than compression.


There are also two extra modes (may be not supported in

future versions):

-mr Use simple RLE compression.

-mw Use modified LZW compression with selectable

dictionary size.


DEFAULT: -m2



-md Set maximum dictionary size (in KB ).

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

If dictionary is disabled, this setting has no effect.

Valid sizes:

-m1..3 n = 1,2,4,8,16,32,64,128,256,512,1024 or 2048

-mw n = 1,2,4,8,16 or 32


Dictionary size selection:

1. Using option "-md", UHARC will never select a

dictionary size greater than . If "-md" is not

used, UHARC will try to use maximum dictionary (n=2048).

2. If data stream size is smaller than , UHARC will use

the smallest dictionary size which is greater than the

data stream.

3. If there is not enough memory for current selection,

UHARC will use the largest dictionary size which is

possible with available memory.


DEFAULT: -md2048



-md[-,+] Disable/enable dictionary-based compression.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

This has effect only with modes "-m1", "-m2" and "-m3".


-md[+] Enable dictionary-based compression.

-md- Disable dictionary-based compression.


Generally, it's NOT RECOMMENDED to disable dictionary-based

compression. Without dictionary, the compression ratio is

almost always worser. But for some data types (e.g. waveform

sounds or photographic true-color pictures), the compression

isn't affected much by dictionary. Using "-md-" in such cases

will speed up the compression process considerably.

If dictionary-based compression is disabled, there are nearly

no differences between the three modes.


DEFAULT: -md+



-mm[-,+] Disable/enable built-in multimedia detection/compression.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

This has effect only with modes "-m1", "-m2" and "-m3".


-mm[+] Enable multimedia detection/compression.

-mm- Disable multimedia detection/compression.


UHARC multimedia detection/compression supports many data

types (8/16-bit mono/stereo waveforms, 24-bit true color

pictures and many other types using 8/16/24/32-bit record

sizes). It's also possible to detect multimedia-like data

in other file types (e.g. in executeables). Therefore it's

NOT RECOMMENDED to disable multimedia detection/compression

unless the user knows, that there is absolutely no chance

to use multimedia compression (e.g. compressing text only).


DEFAULT: -mm+



-o[-,+,p] Set overwrite mode.

~~~~~~~~~~~~~~~~~~~

-op Prompt user before overwriting files.

-o[+] Always overwrite files without asking.

-o- Never overwrite existing files.


Using -op with -y has the same effect as -o[+].

If UHARC shows an overwrite query, the user can select one of

the following options:

"Y" Yes, overwrite current file.

"N" No, don't overwrite current file.

"A" Always Yes, overwrite current file and auto-answer

all following overwrite queries with "Y".

"C" Cancel, don't overwrite and quit process.


DEFAULT: -op



-p<-,r,f> Set path mode.

~~~~~~~~~~~~~~

-p- Store no paths (exclude paths from names).

-pr Store relative paths.

-pf Store full paths including drive letter.


Using option "-pr", paths are stored in relation with the

current directory of each drive (drive letter isn't stored).

With option "-pf" it's possible to backup data from different

drives into one archive and restore all data correctly.


DEFAULT: -pr



-r[-,+] Set subdir recursion mode.

~~~~~~~~~~~~~~~~~~~~~~~~~~

-r[+] Recurse subdirectories.

-r- Don't recurse subdirectories.


If recursion is enabled, matching files are also searched

in all subdirectories (regardless of directory names and

attributes) of all specified directories (commandline and

listfiles).


DEFAULT: -r-



-t

Set extract target directory.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

UHARC will store all extracted files in directory 

.

If 

doesn't already exist, UHARC will create it.


Using this option with the "e" command, 

will be the

'current directory' for extracting. Using this option with

the "x" command, 

will be the root-directory for all

extracted dirs/files.


DEFAULT: not specified



-y[-,+] Set auto-answer mode.

~~~~~~~~~~~~~~~~~~~~~

-y[+] Assume YES on all queries.

-y- Don't auto-answer queries.


Using the option -y[+], all queries, except critical error

messages, don't appear on screen and are auto-answered

with "Y".


DEFAULT: -y-


Example:



In this example, I created a CD-image of BeOS R4.5 with CloneCD, creating a cue-sheet. Command line says "uharc a -d2 -m3 -p- archivename filestakentoarchive"


In other words,

* uharc is in the "system32"-folder, so I can use it wherever I want

* a is for creating the archive

* d2 is just "bonus", gives you some details more while uncompressing

* m3 means you use the best compression method. This is a must

* p- means there won't be any path details added to the archive


* This example adds four files to one archive called "BeOSR45.uha"

* Completed succesfully (2976.9 sec) - it took almost an hour with 1800MHz, but as you can see, it was worth it - the packed image is only 52% of the original.



Extracting the image


Create a batch-file like the following:


Quote:

@echo off

cls

echo unpacking the archive, please wait!

uharc x -y archivename.uha

del uharc.exe

del unpack.bat

(save this as "unpack.bat", together with the archive and uharc.exe in the same folder!)


* x means to extract

* y means, if there are some questions, all are answered "yes" like overwrite etc - this is an optional switch.

tak jak mówisz ale pod jednym warunkiem ze nie beda to np. mp3 czy też avi z tego wzgledu ze one same w sobie sa juz skompresowane, a robi sie to bardzo prosto jeden kolo na innym forum lepiej tego nie mogl wyjasnic wiec skorzystam z jego postu

Tłumaczyć na polski chyba nie trzeba??? Czy trzeba??? :stuck_out_tongue:

pozdro

P.S.

może wiecie/wiesz jak wyciągnąć nazwy 500 katalogów (folderów) do pliku tekstowego??? jakis program? czy moze jakos inaczej?


(Bartlomiej Kwiatkowski) #4

mastermax wiem, że można “w dosie” to zrobić, tylko qrde nie pamiętam poleconka, ale to było coś w stylu:

dir >> nazwa_pliku_tekstowego_który_ma_zawierać_spis

bo normalnie polecenie dir wyświetla wyniki na ekranie a jakoś się robiło, że właśnie zapisywał je do pliku HA! no i jednak dobrze pamiętam, tylko bez spacji przed i po >>, czyli tak:

dir scieżka_dostępu_do_katalogu>>nazwa_pliku_jaką_chcesz
