A ZStandard packer Plugin for the Total Commander

[janika]

great plugin. very useful.
but,
when a compressed zstandard file contains more than one frame, it decompresses the first frame only.
multiple frames in one file are completely normal:
https://github.com/facebook/zstd/blob/dev/doc/zstd_compression_format.md#frames
e.g concatenating two or more zst files.
"The decompressed content of multiple concatenated frames is the concatenation of each frame decompressed content."
can you solve that?

Thanks a lot for this plugin. It is very useful concerning decompression of zstd packed files.

I am using wcx_zstd_1_1_3_5.zip from here: https://franke.ms/Downloads.wiki
Could you please add the defaultextension zstd to pluginst.inf, in addition to zst:

Code: Select all

[plugininstall]
description=Zstandard packer plugin for TotalCommander V1.1.3.6
type=wcx
file=zstd.wcx
file=zstd.wcx64
file=README
file=pluginst.inf
defaultdir=zstd
defaultextension=zst,zstd
version=1.1.3.6

Thanks

Hi Bebbo!

Linux ZSTD packer used in http://www.fsarchiver.org/compression uses compression level 1-22. I believe 22 would be better in compression ratio than rar. Could you implement that?
Tested today with 19 and its marginally better then XZ and 7Z on a large PDF.

Regards.

I'd only installed the plugin as an experiment a while ago and forgot about it, but running a batch file I use from time to time it seems to crash TC11beta when you call it to open a tab focusing on a path, file:

Code: Select all

c:\totalcmd\TOTALCMD.EXE /O /T /S /R="c:\downloads\test.md"

TC Crashes:

---------------------------
Error
---------------------------
Error in packer plugin "zst" calling CanYouHandleThisFileW for
"c:\downloads\test.md\" !
Please report this error to the plugin author!

The reported error is:
Access violation at address 72BF150B. Read of address 003A1048
---------------------------
OK
---------------------------

I've removed the plugin and that (obviously) solved the problem.

The plugin seems to dislike the trailing backslash, which is probably appended because you pass "c:\downloads\test.md" as a directory. I will change it.

For the historians

11.07.23 Fixed: Passing an archive name to Total Commander via command line would call CanYouHandleThisFile with a trailing backslash (32/64)
