#104 Direct extraction without temp files

[Anonymous]

A switch or intelligent check to allow direct extraction
from the exe to the hdd without having to go through
sizable temp files.

I have a 500mb installer, the resulting install is 900mb, it
requires 1.8gig of free space or it will fail.

Temporary files are only used for solid compression. Otherwise
everything would have to be decompressed many times if
files are not extracted in the same order as the files have in
the datablock.

Solid compression is enabled by default for BZip2 and LZMA
compression. You can recompile NSIS to disable it.
