TinyTools For Compress and Split

[Gupta]

you can't extract arc files compressed using external compressor without having properly defined "arc.ini" unless you have the cls
and also when using ISDONE for extraction you have to explicitly define where the arc.ini is (see red part)
if not ISArcExtract ( 0, 0, ExpandConstant('{src}\arc.arc'), ExpandConstant('{app}\'), '', false, '', ExpandConstant('{tmp}\arc.ini'), ExpandConstant('{app}\'), notPCFonFLY{PCFonFLY}) then break;

i don't think there is a CLs for reflate, so your arc.ini should contain a section for reflate decompression
