There are a few, mostly for pdf, png, swf files, but I was too lazy to create a new group. It doesn't make a difference either.

Metro Exodus Compression ?

Try vfx unpacker, pack loose files, then afterwards metroex tool to recompress.

Vfx unpacker can I get help with usage ?

How Do I Restore The Files To Their Original State ?

What Would you suggest as an ultra compression method ?

ZAZA4EVER , Can you please tell how to skip compressing "-boot-flow-logo.bik & -test-fmv-Cutscene.bik" with bpk in ultraarc ?
i used "arc.groups", but in vain , bpk always won't skip them and show errors !thanks!

You have to write every single bik/bk2 file down into arc.groups (remove *.bpk, *.bk2 from arc.groups) except for the two mentionel files.

To do this the fast way, make a batch file in game folder and execute to save all *.bk2 files into a text file
Copy the contens of the text file to arc.groups $binkpack

PS: If you open the text file, maybe you have to remove driveletter:\gamefolder before (just press ctrl+h in notepad and replace driveletter:\gamefolder with nothing (just leave "replace with" blank)).
PPS: If the game use *.bik files instead of *.bk2, replace *.bk2 with *.bik in your batch.

I remember trying to make a precompressor for this but I just didn't finish it and I no longer have the game so I guess I should download it first and try to write the complete code for precompression. :(

Not specific, but more general: is there a way to pause Arc compression and return again?

If I wanted to stop overnight then begin the following day: is this possible?

I know you can click the command window and click "select" - perhaps doing this and then putting the computer to sleep would have the desired effect?

Ctrl+S in a CMD window, or click on icon of the window, select edit and mark. After you mark the text, the process pauses. Pressing Enter will resume the window.

And yes, if you pause it that way and put it in sleep/hibernate - it will resume. Hibernation is guaranteed to resume properly, not so sure about sleep.
