INTRODUCTION
|
||
|
|
============
|
||
|
|
|
||
|
|
UPX is an advanced executable file compressor. UPX will typically
|
||
|
|
reduce the file size of programs and DLLs by around 50%-70%, thus
|
||
|
|
reducing disk space, network load times, download times and
|
||
|
|
other distribution and storage costs.
|
||
|
|
|
||
|
|
Programs and libraries compressed by UPX are completely self-contained
|
||
|
|
and run exactly as before, with no runtime or memory penalty for most
|
||
|
|
of the supported formats.
|
||
|
|
|
||
|
|
UPX supports a number of different executable formats, including
|
||
|
|
Windows 95/98/ME/NT/2000/XP/CE programs and DLLs, DOS programs,
|
||
|
|
and Linux executables and kernels.
|
||
|
|
|
||
|
|
UPX is free software distributed under the term of the GNU General
|
||
|
|
Public License. Full source code is available.
|
||
|
|
|
||
|
|
UPX may be distributed and used freely, even with commercial applications.
|
||
|
|

|
||
|

SHORT DOCUMENTATION
|
||
|
|
===================
|
||
|
|
|
||
|
|
'upx program.exe' will compress a program or DLL. For best compression
|
||
|
|
results try 'upx --brute program.exe'.
|
||
|
|
|
||
|
|
Please see the file UPX.DOC for the full documentation. The files
|
||
|
|
NEWS and BUGS also contain various tidbits of information.
|
||
|
|

DISCLAIMER
|
||
|
|
==========
|
||
|
|
|
||
|
|
UPX comes with ABSOLUTELY NO WARRANTY; for details see the file LICENSE.
|
||
|
|
|
||
|
|
Having said that, we think that UPX is quite stable now. Indeed we
|
||
|
|
have compressed lots of files without any problems. Also, the
|
||
|
|
current version has undergone several months of beta testing -
|
||
|
|
actually it's almost 8 years since our first public beta.
|
||
|
|
|
||
|
|
This is the first production quality release, and we plan that future
|
||
|
|
releases will be backward compatible with this version.
|
||
|
|
|
||
|
|
Please report all problems or suggestions to the authors. Thanks.

||
|

THE FUTURE
|
||
|
|
==========
|
||
|
|
|
||
|
|
- AArch64 (64-bit ARM) for Linux and iOS.
|
||
|
|
|
||
|
|
- The Linux approach could probably get ported to a lot of other Unix
|
||
|
|
variants, at least for other i386 architectures it shouldn't be too
|
||
|
|
much work. If someone sends me a fresh hard disk and an official
|
||
|
|
FreeBSD/OpenBSD/NetBSD/Solaris/BeOS... CD I might take a look at it ;-)
|
||
|
|
|
||
|
|
- We will *NOT* add any sort of protection and/or encryption.
|
||
|
|
This only gives people a false feeling of security because
|
||
|
|
by definition all protectors/compressors can be broken.
|
||
|
|
And don't trust any advertisement of authors of other executable
|
||
|
|
compressors about this topic - just do a websearch on "unpackers"...
|
||
|
|
|
||
|
|
- Fix all remaining bugs - keep your reports coming ;-)
|
||
|
|
|
||
|
|

|
||
|
|
to contribute.
