Jar is a powerful compression engine but it is a
console application and its use is not very intuitive.
Jarwin provides a classical GUI (such as WinRAR)
for the most useful features of Jar. It also adds a new feature in the
way it can extract files.
Jarwin requires Jar1.02, MFC42.dll and MSVCRT.dll (should be in your system directory).

For more information about Jar, read your Jar documentation.
Jarwin can extract files with their relative path in the archive. Jar can only extract files with their full path or without path. Thanks to extra computation, Jarwin offers a more convenient alternative to these methods.
Jarwin supports drag and drop and provides shell extensions.
You can also compute
the size of the files that you will compress or that you will extract.
Index
Startup Directory
It's the directory where Jarwin will start the next
time you'll load it : the directory of the last opened archive or the directory
of your choice.
Add Directory
It's the directory where Jarwin will add the archive
when you open the Add dialog : the directory of the last created archive,
the current directory or the directory of your choice.
Extract Directory
It's the directory where Jarwin will extract the
archive when you open the Extract dialog : the directory of the last extraction,
the current directory or the directory of your choice.
Temporary Directory
It's the directory that Jar will use to create its
temporary files : the archive directory (ie the -w switch is disabled)
or the directory of your choice (ie the –w switch is enabled with the selected
directory). Jar will run faster is the temporary directory is not on the
same disk as the manipulated files.
Jar Directory
It's the directory where Jarwin can find Jar32.exe.
Jarwin Directory
It's the directory where Jarwin can find Jarwin.exe,
Jarwinshext.dll and Jarwin.cfg. It will be used to store list files.
Associate Jarwin with Jar archives
Check this option to run Jarwin when double-clicking
on an archive in the Explorer.
By unchecking this option, you will restore
the previous association.
Enable Extraction Extension
Check it if you want to enable extraction extension
(context menus in Explorer). This extension allow you to extract an archive
as is in the current directory ('Extract Here'), to extract it in the
specified directory ('Extract to <directory>') or in the directory of your choice ('Extract to ...').
Enable Compression Extension
Check it if you want to enable extraction extension
(context menus in Explorer). This extension allow you to add selected files
to the specified archive ('Add to …'). The list file ~JarwinAdd is created
in your Windows temporary directory.
Default compression rate
It's the compression rate that will be used when
you add files to archive from the Explorer.
Skip Topmost Directory
If you select one directory, the files within the directory will be
added in the root of the archive (same behaviour as Winzip).
Beep when finished
Beeps 3 times when Jarwin has finished the computations
which last at least the number of minutes indicated in Time before enabled.
Edited files compression rate
Sets the compression rate when Jarwin saves in the archive the files that have been edited.
Double-click launches:
Choose the action of the double-click: open the file with its associated program
or view it with the selected program. Note that whatever the action you choose, the other will be available in the context menu and in the toolbar.
Index
Archive name
Select the name of the archive you want to add files
to. The archive may exist or not. You can't add files to a multi-volume
archive (although you can rebuild it, add your files and split it again,
but Jarwin doesn't support it).
Action
Select the action to perform :
Add (command 'a') : adds all files
to the archive replacing existing ones.
Freshen (command 'f') : replaces files
in the archive older than the ones you add. It updates only existing files
in the archive ; the new files are not added.
Update (command 'u') : replaces files
in the archive older than the ones you add. Add also the new files.
Compression
Select the compression method : the Best method
(-m4) should not be used for frequently updated archives because it makes
the update slower. This method proves more efficient than the Better one
for files sets of more than 2 Mb.
Path options
Select the way files are stored in the archive :
Full Path (-jf): the files are stored
with their full path (ie C:\Windows\System\Shell32.dll will be stored as
\Windows\System\Shell32.dll).
Partial Path (-jf) : the files will
be stored just as you selected it : if you selected 'foo.bmp', it will
be stored as 'foo.bmp' ; if you selected the directory 'foo', all files
in this directory will be stored as 'foo\…'. This options is not provided
by Jar and Jarwin has to use a little trick to enable it (see the 'How
it works' section).
No Path : all selected files and files
in selected directories will be added with no path .
Use files list
Check it if you want to add the list you've just
built.
Archive Spanning
When spanning on not fixed disks, the temporary
directory will be set to the Windows temporary directory (commonly C:\Windows\Temp)
; Jar will also beep at the end of each volume (-v modifier v). You can
modify this behaviour by editing the command line.
Span Archive : toggles the spanning
of archive (-v)
Volume size : select the size of each
volume (in thousand bytes, that is 1000 and not 1024). You should use Autodetect
when spanning on floppy disks.
Format Disk : full formats the archive
disk (-v modifier s"format A:"). The first disk must be formatted.
Wipe Disk : wipes the disk (-v modifier
s"deltree /y A:\*"). Becareful: if a disk is write protected, the suppresion
won't work and Jar will hang on (not with the first disk, because Jar checks
it). So press Ctrl+C ONCE and you will be prompted to insert another
disk, then unprotect it and go on.
When extracting an archive spanned on multiple disks, insert first the last disk which contains the *.j file, and then you'll be prompted for the first disk.
Path in Archive
Select the path in the archive where the files will
be stored (-o) . They are added in root by default.
Archive Tree
Toggles the computing of the archive tree. With
huge archives it may take time.
List file only
Only generates the list file ~JarwinAdd in the Jarwin
directory. Does not perform any Jar action. This list file can be useful
if you want to perform Jar commands that Jarwin doesn't support.
Command Line
Toggles the use of the user-made command line that
you can edit with the Edit button.
Extract Directory
Select the directory where you want to extract files
to (-o). It may exist or not.
Extract What
All Files : extracts all files in
the current archive directory.
Selected Files : extracts only the
selected files.
Files List : extracts the files in
the files list.
Path options
Select the way files are extracted from the archive
:
Full Path (command x) : the files
are extracted with their full path (ie \Windows\System\Shell32.dll will
be extracted as <extract directory>\Windows\System\Shell32.dll). When
the files to extract are in the root directory, this option is automatically
set instead of Partial Path which is slower.
Partial Path (command
x) : the files will be extracted just as you selected it : if you selected
'foo.bmp' , it will be extracted as 'foo.bmp' ; if you selected the directory
'foo', all files in this directory will be extracted as 'foo\…'. This options
is not provided by Jar and Jarwin has to make extra manipulation to enable
it (see the 'How it works' section).
No Path (command e) : all selected
files and files in selected directories will be extracted with no path
. When the files to extract are not directories, this option is automatically
set instead of Partial Path which is slower.
Overwrite without prompting
If checked, Jar doesn't ask before overwriting an
existing file (-y).
With the path option 'Partial Path', it's Jarwin
which will ask you for overwriting.
Update options
Select the way files are extracted from the archive
:
None : all selected files are extracted.
Freshen, Newer Files (-f): only files
newer than those on the disk are extracted. Files that are not already
on the disk are not extracted.
Freshen, Older Files (-f1): only files
older than those on the disk are extracted. Files that are not already
on the disk are not extracted.
Freshen, Date changed,etc (-f2): only
files whose date or size has changed compared to those on the disk are
extracted. Files that are not already on the disk are not extracted.
Update, Newer Files (-u): only files
newer than those on the disk are extracted. Files that are not already
on the disk are extracted.
Update, Older Files (-u1): only files
older than those on the disk are extracted. Files that are not already
on the disk are extracted.
Update, Date changed,etc (-u2): only
files whose date or size has changed compared to those on the disk are
extracted. Files that are not already on the disk are extracted.
Chapters
Extract chapters: toggles chapters extraction.
From (-jb): indicates the first chapter to extract (greater or equal to 1).
To (-jb): indicates the last chapter to extract. If you want to extract only one chapter, leave this field empty (=> -jbFrom). If you want to extract all chapters from 'From', set this field to 0 (=> -jbFrom-). If you want to extract several chapters, set this field to a number greater than 'From' (=> -jbFrom-To). Multi-chapter extraction is not allowed with 'Partial path'.
List file only
Only generates the list file ~JarwinExtract in the
Jarwin directory. Does not perform any Jar action. This list file can be
useful if you want to perform Jar commands that Jarwin doesn't support.
Command Line
Toggles the use of the user made command line that
you can edit with the Edit button.
To cancel a Jar operation, open the DOS box and press Ctrl+C.
You can view/open files with the 'View/Open File' command in the context menu and in the toolbar or by double-clicking on them.
Drag and drop support:
When you are in the disk, the title bar indicates the current directory.
When you are in an archive, the title bar indicates the archive full name and the current archive directory. The status bar also shows the uncompressed size of the archive, the number of files (including directories) and the compression ratio, that is the compressed size (not including the archive header) divided by the uncompressed size.
In Details View, you can sort the files by clicking on the corresponding column header. When in an archive, some directories may not have date information. This is because these directories were not stored in the archive.
When running Jar, Jarwin is disabled and you can see that Jar is running in a console in your task bar.
When starting Jarwin by double clicking an archive, the Jarwin window may take time to appear because it retrieves the archive information. Yet the hour-glass disappears before the computing is over and the window is not there , thus you may think that something went wrong but in fact you just have to wait a little.
Jarwin doesn't store directories in the archive, so if you add empty directories, they won't appear in the archive.
Jarwin uses list files instead of wildcards to select the manipulated files. These list files are ~JarwinAdd, ~JarwinExtract and ~JarwinDelete in the Jarwin directory.
When double clicking an archive, Jarwin runs Jar with the v command to retrieve archive information. Then it processes it. This may take some time (about 9 seconds on a Pentium 200 for a 3,000 files archive).
When running Jar, Jarwin uses the following
command scheme:
jar32.exe <command line>
<archive name> !<list file>
For Delete, the command is 'd' and the switches
are '-r- -y'.
The addition with partial path is performed
by placing '.\' between the partial path and the upper path: if you want
to store C:\Toto\Titi\Tata\Tutu.txt as Tata\Tutu.txt just add it full path
as C:\Toto\Titi\.\Tata\Tutu.txt. Jar won't go back in the path further
than the point.
The extraction with partial path is performed
this way:
- A temporary directory
~JarwinTemp is created in the root directory of the extraction drive.
- The files are extracted
full path in this directory.
- Jarwin moves these files
to the extraction directory regarding to the update options.
- The temporary directory
is removed.
If something goes wrong during this process, the
temporary directory may not be deleted.
Jarwin will use at least 0.5Mb RAM just the time
of the retrieving of the archive information plus 0.5Mb per 2500 files
to process (more or less). Jarwin is arbitrarilly limited to 1,250,000
files in an archive (which would require 250Mb to process it).
