Compressed file Decompression Device: File decompression compression

Called the 7z.exe. First search the compressed file in the hard drive, no search to download directly (to be added). Second, the file compression and decompression ... Part of the function to be improved, the code does not have any technical content, nothing more than to maintain the love of technology.
