FTP is a means of transferring files over the internet, without blocking up your email account.
If you’re just transferring a few files for retouching or test files, you might find it easier to use WeTransfer instead.
If you’re transferring a larger number of files, proper FTP software is a more flexible choice. If you’re not already familiar with FTP software, we’d recommend Filezilla, which is free open-source cross-platform FTP software. We use it ourselves, so we’ve written some instructions to get you started.
