How to Extract 7Z Files

By Marshal M. Rosenthal

Compressed files can be transmitted more quickly through the Internet and with less chance of errors than a regular file. The “7Z” compressed file format is highly customizable as to the way the file is compressed and so has become well-liked among computer users. Extracting a “7Z” file from its compressed state requires the use of a 7Z decompression program, of which there are only a few due to the recent introduction of the “7Z” compression format. These programs are available for both Mac and PCs. Some programs are free, while others can be used on a limited trial basis.

Step 1

Download a 7Z decompression program to the computer’s desktop, for example, the free 7-Zip program for a PC or the free trial version of the Ez7Z program for a Mac. Double-click the file once downloaded. Follow the menu commands to install the program onto the computer’s hard drive. Restart the PC after the installation is done.

Step 2

Launch the 7Z decompression program by selecting it from the “start,” “All Applications” pop-up menu, or by double-clicking its icon inside of the “Applications” folder if on a Mac.

Step 3

Click the “Add” or “+” button on the 7Z decompression program’s main screen if on a PC. Navigate to the 7Z compressed file in the window that appears. Double-click on the 7Z compressed file to make the window go away. Drag the 7Z compressed file onto the icon of the 7Z decompression program if on a Mac--the icon is in the dock to the left or at the bottom of the screen.

Step 4

Select the “Browse” button next to the “Destinations” or “File Output” tab on the 7Z decompression program’s main screen. Name the decompressed file that is about to be made in the “Name” column at the top of the window that appears, or leave it blank. Select “Desktop” from the “Locations” drop-down menu at the middle of the window. Click the “OK” button at the bottom of the window to make the window go away.

Step 5

Click the “Start” or “Convert” button on the 7Z decompression program’s main screen. Wait as a progress bar appears at the bottom of the 7Z decompression program’s main screen and fills in from left to right. Quit the 7Z decompression program once the progress bar has completely filled in. Archive or delete the 7Z compressed file.
