About Fastmail file storage

The Files screen lets you store and manage files from within your Fastmail account.


Files also have the following legacy features that you can still use, although no additional development or enhancements are planned:

Read on to discover more about:

File quota

The amount of storage space you can use depends on your account plan. You can read about the files quota for each account type as well as their respective bandwidth transfer limits on our account limits page.

Other people downloading your files via the web counts towards your transfer, as do uploads and downloads via DAV or FTP. The maximum file size you can upload is 50 MB.

You can see an overview of your quota usage in the sidebar on the Files screen.

Your files quota is completely separate from your mail quota, so if you reach your file storage or bandwidth limits your mail will remain unaffected.

Accessing your files

If you're accessing your files through DAV or FTP it is shown by the full path /yourusername.yourmail.domain/files/.

Upload/download files and folders

Files can be uploaded from your computer into your Fastmail storage by dragging and dropping, or by using the Upload button. It doesn't matter how you access Fastmail (computer; tablet or phone on web; or the mobile app), you have access to your files anywhere you are connected to your Fastmail email.

You can upload a single file, or select multiple files to upload at once.

When uploading files of the same name as those already stored, you can choose whether to skip the upload, overwrite (replace) the files, or keep both. Renaming adds a number to the duplicate filenames so you can tell them apart: filename[1].ext, filename[2].ext and so on.

You can download a single file at a time, or download the contents of an entire folder in a compressed folder bundle (ZIP file) by selecting the file or folder, and using the Download link in the details panel or the button in the action bar. Windows, Mac and Unix users can open the downloaded ZIP by double-clicking on the file. Mobile users (Android, iOS, etc) will need to install an app that can handle ZIP files to unpack a folder of files. Single files are downloaded uncompressed.

Manage folders

Store your files with ease in folders.

Manage files

For security reasons, our file viewer follows the same content security policy as mail attachments.

To find files or folders, use the search field. You can use a * wildcard character (which matches any number of characters) or a ? character (which matches a single character) within your search field if you're not sure of the filename. Searching is case-insensitive. You can read more about how file searching works here.

To change the sort display on the file list, use the Sort dropdown to choose whether to sort by Name, Size, Created date, or Modified date in ascending or descending order.

Trash: deleting items

Files and folders that are moved into the Trash folder (via the **Delete** button or drag and drop), will be permanently deleted after 30 days.

To permanently delete a file or folder once it is in the Trash, select it and use the Delete permanently button.
