1. INTRODUCTION
|
|
---------------
|
|
This is a utility to handle version 6 of the InstallShield cabinet files.
|
|
Its based on i5comp by -] fOSSiL [-, so, thank him first. Without his
|
|
excellent work, this one would not exist.
|
|
All features are present from i5comp. What changed was the data structures
|
|
only. The decompression routines are handled in ZD51145.DLL.
|
|
|
|
I hope that no body flames me for using the i5comp readme, but i suck big
|
|
time when it comes to writting docs.
|
|
|
|
Changes/New features are:
|
|
|
|
- [DarkSoul] Added bugix to aviod general exceptions. Should now work
|
|
without errors on IS 6.3 cabinet files. I changed nothing else,
|
|
so don't ask me if you still get errors!
|
|
|
|
- [MORLAC] Converting multi-volume cabinets to a single one has been removed.
|
|
No longer needed. Adding a file is not tested and propably wont work.
|
|
|
|
- [MORLAC] Multi-Volume Cab's are supported. Cab's must be of the form:
|
|
Data1.cab, Data2.cab, Data3.cab ...etc.
|
|
This works in the case where all these files share the same Data1.hdr
|
|
Of course, the name "Data" can be anyother like lw1.cab, lw2.cab...etc.
|
|
:-)
|
|
|
|
|
|
- [MORLAC] Now -f works with commands e and x, i.e:
|
|
|
|
i6comp x -f data1.cab (files are decompressed under File Groups
|
|
and subdirs)
|
|
or
|
|
i6comp e -f data1.cab (files are decompressed into their File
|
|
Group sub-directory)
|
|
|
|
- Added AutoDetect for cabinet version (yay!)
|
|
It is no longer necessary to specify -v in most cases, only if
|
|
autodetect fails for some reason
|
|
|
|
- New option -o: suppresses any extra output, like comments, start msg
|
|
(easier to make wrappers/GUI)
|
|
Please note, that it will not suppress error and warning messages
|
|
|
|
- New option -f: treat File Groups as directories
|
|
Now u can use it instead of -g and specify filegroup name as u would
|
|
specify a folder, i.e.:
|
|
|
|
i6comp a -f data1.cab "English Intel 32 Files" *.dll
|
|
(this will add all .dll files in the current dir to the
|
|
filegroup "English Intel 32 Files" in data1.cab)
|
|
or
|
|
i6comp a -r -f data1.cab "English Intel 32 Files\Lalala\*"
|
|
(this will add all files and subdirs starting from the
|
|
"English Intel 32 Files\Lalala" directory to the subdir
|
|
Lalala inside filegroup "English Intel 32 Files" in data1.cab)
|
|
|
|
Other variants are possible too.
|
|
This option was really intended for use with Far MultiArc plugin,
|
|
see the next item ;)
|
|
|
|
- Far MultiArc plugin script
|
|
U can now use Far to browse IS cabinets and do some basic operations.
|
|
There are some limitations of course - MultiArc cannot add files to
|
|
a subdir inside an archive, so u have to work around by adding whole
|
|
directories to the root of a cabinet, which is a list of File Groups ;)
|
|
Please look at the attached Far-Arc.txt file for more details
|
|
|
|
- Changed format of listings: mostly extended Size fields
|
|
(uhm, files are getting bigger now, need more space ;)
|
|
|
|
- Source code is now included with this version. You are welcome to make
|
|
changes and recompile, the only thing I will ask is that u update the
|
|
version to something like 2.<YourNick>.x in the start message :).
|
|
|
|
Other than that - RTFM !
|
|
|
|
|
|
2. INSTALLATION
|
|
---------------
|
|
1) Put 'i6comp.exe' wherever u want (preferrably somewhere in PATH).
|
|
2) Put 'zd*.dll' files in %WinSysDir%. For example, on Win95 that
|
|
might be 'C:\WINDOWS\SYSTEM' and on NT - 'C:\WINNT40\SYSTEM32'.
|
|
Or u can put these files anywhere in PATH.
|
|
|
|
|
|
3. CONCEPTS
|
|
-----------
|
|
1) COMMAND SYNTAX
|
|
Unlike weird icomp.exe, i6comp mimics the command syntax of ARJ/RAR
|
|
style compressors, but the big difference is that the established syntax
|
|
order can not be broken, meaning that u have to specify <cmd> [-opts] <cab>
|
|
in this order, no mixing is allowed.
|
|
Just run i6comp with no parameters to see the explanation of syntax,
|
|
commands and options.
|
|
|
|
2) FILE INDEX
|
|
Every file inside a cab has a fixed index. U can see that index when u
|
|
do 'i6comp l your.cab' in the 'Ind' column. InstallShield allows duplicate
|
|
filenames within one cab, so u might have to referr to the file by its
|
|
index to ensure that u extract/replace the right one.
|
|
|
|
3) MASK MATCHING
|
|
In addition to the references to files by name and index u can use
|
|
filemasks ('fmask' for short in the command line help). The mask matching in
|
|
i6comp is extended compared to standard DOS one. U can use, for example,
|
|
masks like this : a*b.dll, *b?c?d*.d*, etc. For example, '*b?c*.dll' will
|
|
match with 'boc.dll', 'bac12.dll', 'aablc.dll', but will NOT match 'bc.dll'.
|
|
|
|
4) FILEGROUPS
|
|
Every file inside a cab belongs to some FileGroup. Because of this
|
|
structure, u have to specify a FileGroup with a -g option when adding files
|
|
to a cab. Alternatively, u cab use -f mode of i5comp, in which FileGroups
|
|
are treated as directories.
|
|
|
|
5) COMPRESSION DLLs
|
|
Somewhere in the middle of the development of versions 5.x InstallShield
|
|
changed the way the files are being compressed. Because of that the option -v
|
|
was created. It allows u to specify which version of compression dll to use.
|
|
With InstallShield ver 6, they changed the file structures inside the cabinet
|
|
but they did not change the way the files are compressed.
|
|
|
|
|
|
|
|
4. UNSUPPORTED
|
|
--------------
|
|
1) Compressed files that span more than one cabinet are not tested and i
|
|
dont think they exist.
|
|
|
|
2) CAB creation functionality was never intended and required too much
|
|
effort, especially since u can create CABs with InstallShield itself.
|
|
