MultiPar (set of PAR clients and GUI)
|
|
|
|
/* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * */
|
|
|
|
[ Introduction ]
|
|
|
|
MultiPar was made as an alternative to QuickPar.
|
|
The GUI is similar to QuickPar by getting agreement from Peter Clements.
|
|
While it looks like a multi-lingual version of QuickPar,
|
|
there are some good features; Unicode characters, directory-tree,
|
|
faster repairing, smaller recovery files, batch scripting, and so on.
|
|
|
|
[ Feature ]
|
|
|
|
MultiPar supports both PAR 1.0 and PAR 2.0 specifications.
|
|
See "http://parchive.sourceforge.net/" for details of Parchive.
|
|
MultiPar uses UTF-8 or UTF-16 to treat filenames with non-ASCII characters.
|
|
While MultiPar and par2cmdline can treat sub-directory and UTF-8 filename,
|
|
QuickPar and other PAR2 clients cannot treat them.
|
|
Almost all PAR2 clients don't support UTF-16 filename and comment.
|
|
Be careful to use those special features.
|
|
|
|
[ System requirement ]
|
|
|
|
MultiPar requires a PC with Windows 7 or later (Windows 8, 10, 11).
|
|
|
|
[ Usage manual or Help documents ]
|
|
|
|
There are some usage manual or help documents in "help" folder.
|
|
English pages exists in "help/0409" folder.
|
|
You may open the manual by pushing "F1-key", while using MultiPar.
|
|
|

[ Failure, Fault or Mistake ]
|
|
|
|
Use this application at your own risk, because I might miss something.
|
|
If you find something odd behavior, report the incident to me.
|
|
Some examples like output-log, screen-shot, file name, file size, your PC spec,
|
|
and detailes (when / where / what / how) are helpful to solve problems.
|
|
Please contain them as possible as you can.
|
|
Then, I will fix it at next version.
|
|
|
|
[ Security risk ]
|
|
|
|
You should treat PAR files in a same security level as their source files.
|
|
When you have secret data on some files and encrypt them,
|
|
you must create PAR files from their encrypted files.
|
|
If you create PAR files from non-encrypted files,
|
|
others may know how is the original secret data.
|
|
Even when there is no enough redundancy to recover it completely,
|
|
their PAR files may reveal useful information for a spy.
|
|
|
|
Parchive doesn't prevent an intended modification.
|
|
Recovering with unknown PAR files is same as copying unknown files on your PC.
|
|
The reliability of recovered files depends on their PAR files.
|
|
PAR clients may modify original valid files into something invalid files,
|
|
when PAR files were modified by a malicious cracker.
|
|
For example, if someone created PAR files from his modified source files,
|
|
the PAR files will damage your complete source files.
|
|
|
|
[ PAR 3.0 is not finished yet ]
|
|
|
|
PAR 3.0 in MultiPar is implemented only for personal testing purpose.
|
|
Because I modify its algorithm and format sometimes while writing the proposal,
|
|
current samples won't be compatible with future PAR 3.0 specifications.
|
|
Don't send current PAR3 files to others, who may not have the same version.
|
|
|
|
Currently sample PAR3 isn't available, while the specification is being updated.

[ How to install or uninstall with installer package ]
|
|
|
|
Double click setup file ( MultiPar133_setup.exe or something like this name ),
|
|
and follow the installer dialog.
|
|
At version up, if you want to use previous setting, overwrite install is possible.
|
|
Before overwrite install, you should un-check "Integrate MultiPar into Shell".
|
|
You may need to re-start OS after overwrite install or uninstall rarely.
|
|
To install under "Program Files" or "Program Files (x86)" directory,
|
|
you must select "Install for all users" at the first dialog.
|
|
|
|
You can uninstall through the Windows OS's Control Panel,
|
|
or double click unins000.exe in a folder which MultiPar was installed.
|
|
Because uninstaller does not delete setting files or newly put files,
|
|
you may delete them by yourself.
|
|
|
|
When you have used installer package, you should not move install folder.
|
|
Or else, you will fail to uninstall later.
|
|
|
|
[ Installation for multiple users by installer package ]
|
|
|
|
If multiple users may log-on a PC, the administrator can install MultiPar for everyone.
|
|
By installing with administrative privileges, installer made Start Menu icon,
|
|
Desktop icon, and File association will be available for all users.
|
|
When he installed under "Program Files" directory, each user keeps individual setting.
|
|
When he installed in another folder, all users share same setting.
|
|
In either case, user made icons and association are available for the user only.
|
|
|
|
|
|
[ How to install with archive version ]
|
|
|
|
Unpack compressed file ( MultiPar133.zip or something like this name ) in a folder.
|
|
MultiPar.exe is the interface of MultiPar.
|
|
|
|
You can create short-cut icon or send-to link at Option window later.
|
|
If you associate PAR file extensions ".par" or ".par2" with MultiPar,
|
|
de-associate them from other application like QuickPar at first.
|
|
|
|
[ How to un-install with archive version ]
|
|
|
|
If you associate PAR file with MultiPar, de-associate them from this.
|
|
Delete all files in the install folder, in which you extract files.
|
|
If you installed MultiPar under "Program Files" directory,
|
|
setting data was saved in MultiPar folder under "Application Data" directory,
|
|
so you need to delete the folder.
|
|
|
|
When you integrated MultiPar into shell at Option window,
|
|
you must clear the check before un-install.
|
|
If you have deleted MultiPar.exe already, you can un-install the DLL manually.
|
|
Open "Command Prompt" and change directory to MultiPar's folder,
|
|
then type "RegSvr32.exe /u MultiParShlExt64.dll" to remove shell extension.
|
|
You cannot delete "MultiParShlExt64.dll", while it is used by OS or Explorer.
|
|
You may log-off and log-on again to OS before deleting the file.
|
|
|
|
[ How to change installed folder of archive version ]
|
|
|
|
Move files in the install folder.
|
|
If you associated PAR file with MultiPar, de-associate once, and associate again.
|
|
If you want to use same setting at another PC, copy the setting file "MultiPar.ini".
|
|
If you move MultiPar into "Program Files" directory,
|
|
setting data is saved in MultiPar folder under "Application Data" directory,
|
|
so you need to move "MultiPar.ini" into the folder, too.

[ Support ]
|
|
|
|
I use GitHub issue's page as a web-forum for MultiPar users.
|
|
(URL: "https://github.com/Yutaka-Sawada/MultiPar/issues")
|
|
|
|
My name is Yutaka Sawada.
|
|
E-mail address is "tenfon (at mark) outlook.jp".
|
|
Or "multipar (at mark) outlook.jp" for PayPal usage and
|
|
"tenfon (at mark) users.sourceforge.net" for SourceForge users.
|
|
Because they use a same mail-box, don't send duplicate mails.
|
|
Though e-mail address had been "ten_fon (at mark) mail.goo.ne.jp" ago,
|
|
the mail service ended at March 2014, so don't send to there.
|
|
The (at mark) is format to avoid junk mails, and replace it with "@".
|
|
|
|
I get many spam mails from oversea.
|
|
If an e-mail is detected as junk mail or suspicious,
|
|
mail server may delete it automatically, and I won't see it.
