loadfix.bat is...well, it's a batch file (not really an executable, but a
script of commands to carry out), as the filename implies, and as kludgy
as such things usually are.

There are other types of compression beside archival programs like
(pk)zip.  "pklite", "exepack", "lzexe", "diet", etc. are used to compress
an executable so it takes up less space on disk.  The compressed
executable includes its own decompressor, so you can simply run it and it
quietly decompresses itself into memory without you having to know.  "unp"
(short for UNPack) is a program used to recover the original uncompressed
executable from a compressed one; so is another similar program, "tron".  
A quicky web search should turn one or the other up.
