CLS-PrecompMT (Multi tasking)

[github]

Thanks, that one's working however it will force creating all the output files to where the .dll or arc.exe is, including the compressed file, the temp file folders as well as the log file.

And it seems when several precomp running in parallel to split the task, it will expose a problem I found:

Some zip, 7z files , when only a few files going to be compressed, they will fail the decompress on CRC checks. When they are included in a larger set of files, they will pass the decompress.
And with a large set of files, precomp running in parallel , they will fail to decompress because of CRC errors. I guess the reason is, when those zip, 7z files mixed with large set of files, they work fine. When precomp running in parallel , the whole file set been splitted into multiple sections, and the section doesn't have enough files to save those kids.

The zip,7z files have problems are when you try to run this command

precomp.exe -cn -o1.pcf 121.zip

against them:

None of the given compression and memory levels could be used.
There will be no gain compressing the output file.

I'll try -cl or -cb with precomp's builtin compressing;;
