can compress 64-bit executables

Nspack is an executable compressor for Windows, which exceeds other similar products in features and compression ratio. Not only can it compress exe,dll, ocx, and scr files, but it can compress 64-bit executables, and executables created for the .net platform. When you compress files with archivers such as Zip or Rar, the files inside are not directly executable (they must first be decompressed before executing). Nspack, by contrast,works by compressing an executable file, yet still leaving it runnable without having to decompress it first. One other benefit of using Nspack is that your programs will be harder to crack or reverse-engineer. In order for your programs to be modified, the shell added by Nspack must first be removed, which is more difficult to do.
