Have you ever want to encrypt your software to prevent it from being modify or decompile by others using resources changing software? UPX stands for Ultimate Packer for Executable.
The UPX Compressor application was designed to compress raw executable files to reduce the filesize. Packed software will run like normal software without any decompress. This GUI version works by sending command to the DOS module. User doesnt need to type a single command using this software.

Smart Compressor 1.04 brings you a new and easy way to speed up your computer's performance significantly. This is especially true for files that are written too frequently. When writing to part of a compressed file, the entire file needs to be recompressed. This can be a major performance hit for two reasons.

First, the writing process takes extra RAM and CPU time. Second, when files are recompressed they also get fragmented. This utility allows you to compress all files on your hard-drive based on the Date-Modified time. This allows you to get almost the same savings in disk space with a fraction of the performance hit.

Enhancements:

• Will no longer compress files with the System File attribute (such as ntldr).
