Inno Setup: Delay Before Progress Bar with Large Compressed Archives

All right thanks for the quick reply. So I'm assuming also combined with s rep, makes it take even longer.
I'll just keep with the old fashioned bat files. I can get it to crunch down pretty small, but I'll take that over a fancy gui. Thanks again for the help

Nope, it only takes long because of precomp. I'd avoid it anyway, it doesn't do much in most cases.

It's not because of precomp, it's because of the lack of stdio processing for decompression. Whatever plugin you use to bridge FreeArc with InnoSetup will only record finalbytes written to disk. If you're using $$arcpackedfile$$.tmp / $$arcdatafile$$.tmp for any decompression commands, FreeArc has to write those files to disk, do decompression, THEN write the final files/bytes. This janky process is why you wait forever to see any progress.

You can save all this trouble by using stdin/stdout supported tools for decompression.
