How to Compress Files Using 7-Zip

by Quinten Plummer

Save space on storage devices, like USB jump drives and hard drives, by compressing your files. While the Microsoft Windows offers a native ZIP utility for compressing and archiving files, you can achieve greater compression efficiency with a full-featured, third-party utility like 7-Zip. With 7-Zip, you can choose from several different levels of compression without spending any cash to do so, because 7-Zip is completely free.


Download a free copy of 7-Zip. Install the program and launch it.


Locate the folder containing the file you wish to compress. Select one or more files and then right click on your selection. Hover over the "7-Zip" heading in the pop-up menu that appears and select the "Add to archive" option from the 7-Zip submenu.


Click on the drop-down menu next to the "Compression Level" to select a compression efficiency for your file. Enter a password into the "Enter Password" and "Reenter Password" fields if you'd like to password protect your file.


Click "OK" to begin compression your file.
