7zip 0.7.6.6 new version

Post by *dllee » 2016-12-13, 03:02 UTC

MaxX thanks for your feedback.

7zip 0.7.6.6 new version already public on http://totalcmd.net/plugring/7zip_plugin.html

DeltaFilter already in 7-zip 9.20, so I add the DeltaFilter to 0.7.6.5a to let it can decompress the 7z files with Delta compression for WAV files.

I found 0.8.0.0alpha is still buggy for some cases, so I still use 0.7.6.x for my daily backup, and when I tried to add DeltaFilter to 0.8, I found it only need to add one source file from 7-zip to the project, no code need to modify, then 0.8 can have the feature to decompress DeltaFilter sample, so use the same method to add DeltaFilter to 0.7.6.5a, no others are changed except version for 0.7.6.6.

Using 7-zip 16.x to compress files with different methods, they can still be decompressed by 7zip plugin 0.7.6.6. If you found any file that can not be decompressed, please send me the sample, I will try...

BTW, if you are interested in source code, I use VC++ 2010 Express with Windows SDKs v7.1 for the 0.7.6.6 (and 0.8.0.0alpha).

Hi.

Latest version don't report stats of compression process when compression level is set to "fast" or lower. Also I can't press background button, or any other button until compression is finished.

Thanks for your testing. Sfx will be update to 16.04 (I was using 7-zip 16.02 XD).

About Fast/Fastest, even in old version(0.7.6.5a), it acts the same. I will check this issue. Thanks for your feedback.

7zip encryption settings

Post by *jazzz » 2016-12-28, 08:57 UTC

I cannot find any encryption settings in 7zip. E.g. algorithm, key-bits etc.
If not available, what are the default settings 7zip uses?

To my knowledge, using 7z formats the encryption is AES256 with password key and no choice is given ! The only ontion you have is to encrypt file name/header or not.
To get the options, you just have to chose configure one 7z/7zip format is selected on TC when packing.

A couple of requests:
- Still no support for split archives (.001)
- Could be possible to add support for LZIP (download[dot]savannah[dot]gnu[dot]org/releases/lzip/7zip)?

Thank you
Alex

split is not a real format just a binary copy which tc natively supports (both splitting and joining)
lzip is not part of 7zip it's a distinct format
you might ask for lzo support too but you won't get it in this plugin maybe another

Maybe he means that plugin doesn't support multi-volume 7-Zip archives (which use simple binary splitting)...

There is bug in this plugin: when packing data into SFX archive it appends SFX module data (starting with MZ) after existing one. It means that output file has structure like "original SFX module + plugin SFX module + 7z archive data".

It does not affects unpacking due to searching of 7z signature as archive start, but it does break synchronization of folders. Let's say left panel is some folder on disk, right panel is contents of SFX archive - then if we try to compare folders we will get empty right panel.

Fix it, please.

yes but it doesn't need to as 7zip does not have multivolume support it uses binary split which TC supports natively
just select the 7z file you want to split and in TC select Files->Split Files...
TC can merge *.001 files too just select the first ie 001 file and select Files->Combine Files... you don't need 7zip for that
