If you'd like to ensure the smoothest possible upload for your files, and the smoothest possible download for your recipient, you should consider compressing your files into a .zip folder. Have no fear, though - it's a simple task, which we'll explain here:

For Windows 10:

• Open your ‘File Explorer’.

• Locate the file or folder that you want to zip.

• Right-click on the file or folder, select ‘Send to’, and then select ‘Compressed (zipped)’ folder.

• A new zipped folder with the same name is created in the same location. To rename it, right-click the folder, select ‘Rename’, and then type the new name.

For a Mac:

• Locate the items to zip in the Mac Finder (file system)

• Right-click on a file, folder, or files you want to zip.

• Select “Compress [file]" where [file] is the name of the file you want to zip.

• Find the newly created .zip archive in the same directory.

If you're on a mobile device, such as an iPhone or Android device, you won't be able to do this natively. Creating a .zip folder on mobile devices would mean that you need to install a third-party app. We'd recommend one called WinZip. You can find it in the Google Play Store here, or if you're on iOS, the App Store here.
