Free UPX 3.0

Files are constantly under threat every single day. One single error in any sort of modification can completely break any file and render it completely worthless. This risk goes double for a compression program, as minimizing a file's size always comes with a chance of corruption. If the archive gets corrupted, though, every file inside will also get corrupted. All's not lost though - Free UPX will do its best to repair that archives.

Free UPX is easy to install. Simply unzip it from its archive and run the correct executable depending on what bit your OS is in. Then follow the installer and you're good to go. Its interface is incredibly straightforward, with it being rather empty until you add files using either the file browser or drag-and-drop.

The files will have a ton of details, including name, format, directory, packing status, original and packed size, compression ratio, compressor, method, level, and filter. It's possible to point out the saving directory and compression type, force compression, comppress the export section, strip relocations, as well as include resources in the compression. If this sounds a bit overwhelming for you, then there are several preset profiles that are available as well. Finally, once you get the correct setup, then you can save the options to INI files, or BAT files.

On top of all that, the program runs on a very low amount of CPU and RAM, so it doesn't affect the performance of the computer at all. All in all, if you need to fix your archives, then you should give Free UPX a download.
