Why are binary files required

Zip and unzip files

Zipped (compressed) files take up less space and are faster to transfer to other computers than uncompressed files. In Windows, compressed files and folders can be treated in the same way as uncompressed files and folders. Multiple files can be combined into a single compressed folder for easy sharing.

How to zip (compress) a file or folder

  1. Find the file or folder that you want to compress.

  2. Press and hold (or right-click) the file or folder, select (or point to) Send to, and then select compressed (zipped) folderout.

    A new zipped folder with the same name will be created in the same location. To rename, press and hold the folder or right-click the folder, select Rename then enter the new name.

How to unzip (extract) files and folders from a zipped folder

  1. Navigate to the compressed folder that you want to extract files or folders from.

  2. Do one of the following:

    • To extract a single file or folder, open the compressed folder and drag the file or folder from the zipped folder to a new location.

    • To extract the entire contents of the compressed folder, press and hold or right-click on the folder and then select Extract all out. Then follow the instructions.


  • To add files or folders to a previously zipped folder, drag them into the zipped folder.

  • If you add encrypted files to a compressed folder, the files are decrypted when they are extracted, which can inadvertently reveal personal or confidential information. For this reason, encrypted files should not be compressed.

  • Some file types (such as JPEG images) are already heavily compressed. If several JPEG images are compressed into a folder, the size of this folder will only differ slightly from the size of the original image collection.
