Decompressing the files using 7zip

In this course, you are required to use 7zip, a file decompression software that handles multiple file compression formats commonly used for geospatial data. If you are a registered student at Humboldt State University working in a computer lab, you already have access to the 7zip software. If you are working from home, you will need to install 7zip on your personal computer.

Watch the video above to learn how to install 7zip on your personal computer.

Navigate to your original folder. Right-click on the Fire Hydrants zip file, select 7zip, then extract here.

You can access the 7zip software by right-clicking on a compressed file. Click to view the image in a larger size.

The fire hydrant zip file decompresses, and the contents appear in the original folder. Once the shapefile decompresses, delete the initial fire hydrant zip file from your original folder. You won’t need it anymore. Removing it will save space and help to prevent confusion later.

As you can see, many parts make a shapefile. It must use these files together to work correctly. Click to view the image in a larger size.

Repeat these steps for each of the compressed shapefiles. Be sure to delete the zip files once you are done decompressing them.

When done, you should only have the components of the four shapefiles. Remove the zip files from the original folder. Click to view the image in a larger size.
