About Fastmail File Storage

The Files screen lets you store and manage files at Fastmail to use with your email.


Files also have several legacy features. While legacy features are available, no additional development or enhancements are planned:

Read on to discover more about:

File Quota

The maximum storage space you can use depends on your account plan. We list the files quota for each account type in our limits information. There are also hourly and daily bandwidth transfer limits to prevent abuse. If other people download your files via the web (because you have created a website) then that is still counted towards your transfer. Uploads and downloads via DAV and FTP are also counted. Your files quota is completely separate from your mail quota, so if you reach your file storage or bandwidth limits, your mail is unaffected.

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, and a detailed breakdown by folders on the "Files Usage" screen.

The "My Files" Folder

The folder called "My Files" is special. You cannot delete or rename this folder; it is the top-level folder that contains all of your uploaded content.

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 either via drag and drop, or by using the upload button to access your device's file chooser. It doesn't matter how you access Fastmail (computer; tablet or phone on web; or native 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. Note that Safari does not support drag and drop of folders, only files.

When uploading files of the same name as those already stored, you can choose whether to overwrite (replace) the files, or keep both (rename). 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 (ZIP) bundle 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 on mobile devices are downloaded uncompressed.

An upload can be cancelled from the upload manager by clicking the x mark beside the filename you want to cancel uploading. If your file upload will take some time, you can collapse the upload manager which allows you to continue working.

Manage folders

Store your files with ease in folders.

You can drag and drop folders to move and copy. To copy, hold down Alt or Option before starting to drag; otherwise dragging performs a move. (Drag and drop of folders doesn't work on Safari due to browser limitations)

Manage files

To view file contents, select the file and its details appear in the details panel. Image files display a preview thumbnail in the detail panel. All files can be downloaded, or viewed in the browser (if your browser can display files of that type).

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

To find files or folders, use the search field. The file searcher works via glob matching: 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.

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; and whether to sort up or down.

The file display can be grouped. This is controlled by the arrange dropdown. The ordering of files within each grouping arrangement is controlled by the sort setting. Arrangement options are:

Note: These two settings do not affect the ordering in a website or photo gallery.

You can drag and drop files to move and copy. To copy, hold down Alt or Option before starting to drag; otherwise dragging performs a move.

Editing Files and Folders

When viewing and editing files and folders, the details panel displays information about your selected item. Use the Edit button to allow updating of some aspects of the current item.

For easier editing, the panels can be resized by dragging the bar between the file list and the detail panel.

Trash: deleting items

Files and folders that are moved into the Trash folder (via delete or drag and drop), will be deleted 30 days after they arrived in the Trash.

Do not host photo galleries or websites out of your Trash folder.

To instantly remove a file or folder out of the Trash, select it and use the "Delete permanently" button to remove it. This operation can be undone via the "z" undo keyboard shortcut.
