9 Multi-volume 7z archives. You can open the archive, but it is empty .
10 In the file descript.ion there is no description of the purpose files:
TC7Z.DLL
TC7Z64.DLL
TC7ZIPIF.DLL

Sorry, 7zip SFX modules aren't yet supported by the internal unpacker. They will be supported in a later beta.

ghisler,
It is interesting that some SFX 7Z may be opened with TC internal unpacker while some aren't.
E.g. this one (Windows 7 write.exe packed with 32-bit 7-Zip 9.20 with standard SFX module) TC opens with internal unpacker even when I have Total7zip installed!

Maybe you will consider also that:
- 7zip will be full supported (soon or later)

Why you don't add the path to the executable file (Program Files\7-zip\7zFM.exe) like Arj, lha, WinRAR, obsolete UC2 or ACE.
In my opinion UC2 is so old and obsolete and can be changed with 7zip.
It will be a huge step forward, IMO.

Not 7zFM.exe, it is only file manager, but 7zG.exe, it is GUI packer/unpacker. It uses command line similar to 7z.exe, special option -ad may be used to display packer options dialog.

I think it would be nice to add scroller (TScrollBox component) to TC packer configuration page so more packers would fit into that page.

9 Multi-volume 7z archives. You can open the archive, but it is empty

?

TC is currently looking for the following signature:
37 7A BC AF 27 1C 00 03
however, the files which don't work contain
37 7A BC AF 27 1C 00 04

I can't just use 37 7A BC AF 27 1C 00 because it occurs in the SFX module alone without any data. Any ideas what the difference between these two is? Maybe there are even more?

[MVV]

ghisler,
Does 7z library skip SFX module itself? If yes, you can simply pass file with 37 7A BC AF 27 1C 00 to it because it is a 7z archive (doesn't matter if it is SFX or not).

[gora]

The first 6 bytes - the signature { 37 7A BC AF 27 1C }
The next 2 bytes - version of the format {Major, Minor}: 7-Zip 9.20 writes here { 0, 3 }, and 7-Zip 9.30a wrote { 0, 4 };
Need to check BOTH variants: { 37 7A BC AF 27 1C 00 03 } OR { 37 7A BC AF 27 1C 00 04 }

37 7A BC AF 27 1C 00 04

TC also throws an 'access denied on target file" error for every subfolder of an 7-Zip archive with header 37 7A BC AF 27 1C 00 02 (7-Zip v4.43, v4.57).
The contents and folder structure of theses archives are completely unpacked nevertheless, just the subfolders itself don't get their date/time stamp restored.

[ghisler(Author)]

I just checked, 37 7A BC AF 27 1C 00 is not present in the SFX modules themselves! So checking for that should be sufficient.

Does this concern only self-extracting EXE files, or all files? If all files, can you send me a small test file to support at ghisler dot com, please?

@ghisler

Hi Christian,
I detected this issue using normal archives, I did not test for SFX-archives. Please find a small example archive attached below.


Steps to recreate the archive:

• Press [SHIFT+F4] to create a new file dummy.xxe
• Copy/paste the content of the code box below into file dummy.xxe
• Decode dummy.xxe (Main menu - Files - Decode file).

Code: Select all

The files 7z.sfx, 7zCon.sfx (version 9.30), this signature appears twice!

I tried the sfx files in Modules20.exe and Modules30.exe - no problem.

2ghisler(Author)
Sorry, I did not understand.
In these files, there is no signature or you can not reproduce the problem from the first post?
