7z All Files

7z All Files is a JScript program that uses 7-Zip to compress every individual file in the folder in which the script is executed into a 7Z compressed file using optimal compression settings. You must have 7-Zip installed on your computer. If the path is different than the source, simply change the path in the code. This script is similar to 7z All Folders.

To use the program, copy and paste the following source code into a file named "7z all files.js", then move the file into the folder you want and double-click it. Every file in the folder will be compressed into a 7Z file with the same name as the file.
