To attach a file or a folder containing a number of files, choose one of the two paperclip icons at the bottom of the message:
- The icon with a paperclip over a file will ask you to select files from your computer. Use the shift button + mouse to select multiple files.
- The icon with a paperclip over a folder will ask you to select a folder from your computer. The folder will be compressed into a .zip file before sending, which is a much more convenient way to share a number of files.
Select the files or folders to upload, then click the Choose for Upload button.
