Sometimes it happens that, while using a CMS, you need to upload large amounts of data such as a whole photo gallery. Almost every software allows the upload of multiple files but sometimes this functionality alone is not enough.
This functionality is accessible through File Manager and it helps uploading a zipped archive with all your documents and proceeding then with its extraction.
The special button marked with the icon here represented starts the extraction of the files on the server and the whole bunch of your documents organized in folders will then appear on your PC.
This is a powerful utility that helps speeding up basic operations on files and their organization.
