Thanks.
Is there an option to specify the output directory of the compressed data?
before using this, my bat is
arc.exe data/data1.bin
but with this cls-precomp.ini and cls-precomp.dll, mt works however the compressed file will write in to the place where .ini/.dll or arc.exe is, it doesn't do the data/data1.bin anymore.
Same happens to the temporary file folders and log file.
Edit:
I gave this a go with various file sets, on a folder with some .zip and .xlsx files, compressing is fine and about 25% faster than without this.
But decompressing always fail with a particular .zip or a .xlsx file.
