7Pack REV a FAST GZIP based (de)compressor

Note:Fsharpcore.dll allows it to work,include it your innoscript!!
Note2:currently working on an LZ77 based version in AMD64_Assembly


arc.ini\/

[External compressor:7pack]
packcmd=SevenpackREV.exe --compress $$arcdatafile$$.tmp $$arcpackedfile$$.tmp
unpackcmd=SevenpackREV --decompress $$arcpackedfile$$.tmp $$arcdatafile$$.tmp

Note:Fsharpcore.dll allows it to work,include it your innoscript!!

works with 2gb files aswell,it dispises 4gb and above files (currently working on)(seem like its a FARC thing,it handles the file perfectly in cmd when called directly)

keep up the work

,but could you test a massive file (8gb for instance) in cmd and farc (2nd bug discovered,bad decompression on a game test (system shock remake) it only decompresses about 2-3 MB)

going to try and make FstGz in F# as fastlz.h (and fastlz.c) are 32 bit files(why i dont know) instead

Sorry for late response, medical exams ;(
for now no errors but not so fancy ratio
