Masked Compression (Ultimate compression in one go)

[panker1992]

@Lucas its fine to use reflate only, tho as i said this version of inno setup i use refuses to see reflating as external compressor.
but if you have found a way to use it that is good news

did you notice any difference in ratio or speed while using the Masks ?? will be glad to know

@vint i saw that now i only check the entire data.bin for ratio

this is because some data are non compressible

in this case there are 3 scenarios
1) turn precomp to brute mode from intensive
2) lossy compress the files manually
3) if it is a packed format of games for example .pack formats used by all Total Wars
then you extract the content and compress it and then make a bat to restore it
