A ZStandard packer Plugin for the Total Commander

[bebbo]

I wrote a WCX plugin for zstandard http://www.zstd.net/. The packer supports packing of one file, so apply tar before using zstd.

Feel free to download at http://franke.ms/packer/zstd.wiki and test it.

Thanks for the plugin. However, it does not show the unpacked size yet.

here's a long thread @encode.ru about Zstandard

Thanks for the plugin. However, it does not show the unpacked size yet.

The size is displayed if the compressed file contains the info of the uncompressed size.

Unfortunately most archives are created using a zstandard stream (many compressed chunks), and then the uncompressed size is not stored.

Thank you for this plugin and good idea of using zstd as it is probably the best compression algorithm out there in term of speed and compression ratio.

Unfortunately there is maybe bug in this version of plugin that it doesn't create readable archives in case compressed file is bigger then 2GB. In this case it also sometimes cause TC crash. That is pity.

Tested with TC 32&64 bit, 8.5 and 9.0a.

Good news: the created files are ok. The bug is in the reading part, where opening fails. It's fixed locally so I will soon publish an update.

Thank you Bebbo.
Support for your plugin is better than professional.
I just tested it and it is working like a charm.
It is now the best packer plugin for big files like virtual machines disks etc.

If you could support the StartMemPack, PackToMem and DoneMemPack functions, and return PK_CAPS_MEMPACK in GetPackerCaps, then TC could create .tar.zst files directly.

If the zst API works with callbacks, you could create a background thread for packing, and pass the data blocks received from PackToMem to that thread, where the callback would pass the data to the packer.

Sorry, I don't see a benefit.

Plus (according to wcx_ref2.21se.zip) there is only

Code: Select all

int __stdcall StartMemPack (int Options, char *FileName);

but not:

Code: Select all

int __stdcall StartMemPackW (int Options, wchar_t *FileName);

And it's not clear how to return error codes...

I have Windows 10 Home Version 10.0.14393 64bit and Totcmd 9.0a 64bit.
i installed WCX Zstandard packer plugin 1.1.3.4 32/64bit
This plugin works fine with zst extension files but
if i try to unpack any file type that is not a packed file like plain txt file,
TC crashes with alert message:
Total commander has stopped working. a problem caused the program to stop working correctly.
It does not matter if the file has extension ot not.
no entry in TC log file.
If the file is zero size, then the crash is even without an alert message.
This error dose not occurs with other packer plugins (z.wcx, iso.wcx, gifwcx.wcx, total7zip.wcx...)

Just to clarify: sometimes file does not have extension and I want to check if it is a packed file. Sometimes file have a packed type extension but actually it is not. Sometimes I select a lot of files to unpack and it includes some files that are not packed and etc.
