Compression time: cpu 13.81 sec/real 304.75 sec = 5%. Speed 45.06 mB/s
All OK

Key

Code:

0xF31F7A2739450967A8143CD631C61433121A51FCFD20D362 EF8884488BA3C263

I tested compressing the "Potentia-WindowsNoEditor.pak" file = 12.8 GB (13,779,750,608 bytes)

The configuration used with XTool was:

Code:

xtool_ue4:m1:k0xF31F7A2739450967A8143CD631C61433121A51FCFD20D362EF8884488BA3C263

Code:

[External compressor:xtool_ue4]
header    = 0
packcmd   = "PRE\XTool_2020\Win64\XTool.exe" precomp -mzlib+ue4{:option} -c32mb -t100p -d1 --dbase - - <stdin> <stdout>

I don't know why but the Arc.exe returns return a value less than the file size (4.683.535.036 bytes = Ratio 33.99%), but the destination file was 23.1 GB (24,890,734,065 bytes)
Could someone do the test combining with zlib (Xtool.exe -mzlib+ue4:..) to see if only this happens or is it a bug in XTool or ARc.exe?
