DeveMultiCompressor

A tool to compress files with multiple compressors to find out which one gives the best compression.

Arguments and usage

The tool should be used with the following arguments:

Short	Argument	Description
-d	--decompress	If this is set, the program will try to decompress the file instead of compressing it.
-i	--inputfile	Required. The path to the input file to compress.
-p	--precomp	Precompresses all files before compressing them. (When compressing, first precomp the files. When decompressing, extract all .pcf files).
-v	--verify	Unpacks the archive afterwards and compares the recreated file hash with the input file. (Only for compressing).
	--include	Included compressors (List of archive extensions seperated by a comma, e.g.: nz,7z,zpaq).
	--exclude	Excluded compressors (List of archive extensions seperated by a comma, e.g.: nz,7z,zpaq).
	--help	Display the help screen.
	--version	Display version information.

See the sample #SampleCompressEnwik6.cmd in downloaded package for a sample command.

The output (created archives) will be written to a folder named "Output".

After the compression is done the tool will show the statistics on all the compressors used.
