And we need a unlocker like winrar to unzip this folder again. Sometime, where we can't attach multiple files there zip file is a good solution. We can put multiple files in a folder then compress it to a zip folder and can attach it.

Windows machine should comes with unzip feature by default. Here are the steps to unzip a file:

Locate the zipped folder that you want to unzip (extract) files or folders from

- To unzip a single file or folder, open the zipped folder, then drag the file or folder from the zipped folder to a new location.

- To unzip all the contents of the zipped folder, press and hold (or right-click) the folder, select Extract All, and then follow the instructions.

Please try it.

Thank you.
