Files

To let people add photos and documents in your app, ask the agent in a thread. After you push the change, Backend › Files lists your app’s folders and the files saved in each, and Rules shows what each folder takes and who can open its files. Only owners and developers can see Backend › Files.

What to ask

Your app keeps its files in folders, and each folder has its own rules. In your request, say what people save, which screens use it, who can open the files, and which kinds and sizes of file to accept:

Example request

“Let people add a photo to each expense. Only the person who added an expense can open its photo. Accept JPEG, PNG, and HEIC photos up to 10 MB.”

Example request

“Let people attach a PDF receipt when they add an expense, and show a link to it on the expense screen.”

To change how an existing folder works, open Backend › Files › Rules, and then click Ask for a change at the end of the page. A new thread opens with “Change how the app stores files: “ in the composer, for you to finish and send.

Agent questions

If the agent shows a Question or Approval card while it works, read the card and answer the agent to continue.

Review

Before you push the change, check the screens that save and show files.

After the agent finishes, read the turn’s Summary and review its Changes. Check the affected screens in Screens, and try the change in Preview. If the change uses records or sign-in, test it with the thread’s own data in Data.

After you push a backend change, check the result in Backend.

Push

To add the folders and their rules to your app, push the thread.

Access rules

Backend › Files › Rules shows one card for each folder, under the folder’s name. You can’t edit the rules there. To change them, ask in a thread.

Each card shows the following rows. Who can upload and Who can delete show only when the folder has access rules.

Row What it says
Who can open Anyone with the link for a public folder. For a private folder, the folder’s rule, such as Signed-in people or Only the person it belongs to.
Who can upload Who can add files to the folder from your app.
Who can delete Who can delete the folder’s files from your app.
Kinds of files The kinds of file the folder takes, such as JPEG, PNG and WebP, Any image or Any kind of file.
Largest file The largest file the folder takes, such as 10 MB.
Unused files

The folder’s setting for a file that no record points to anymore, such as Unused files deleted after 7 days or Kept forever. Whatever it says, FlutterFlow doesn’t delete unused files on its own.

The rule values mean the same as they do for a table. See Access rules.

Find a file

Backend › Files lists your app’s folders. Each folder shows its Files count and its Access: Public or Private. To see a folder’s files, click the folder. They’re listed newest first, each with its File name, Size, Uploaded by, Uploaded date, and Access.

To see a file’s details, click its row. The file’s sheet shows its kind and size, Folder, Uploaded by, Uploaded, and Access.

Upload a file

A file that you upload in Backend › Files goes into your app’s live data. To upload files, follow these steps:

  1. In Backend › Files, click Upload, and then choose one or more files.
  2. If your app has more than one folder, choose a Folder.
  3. In Uploaded by, choose who the files belong to: You (the builder account) when your app has one, No one, or a person from People.
  4. Click Upload.

Download a file

To download a file, click Download at the end of its row, or click Download in its sheet.

Rename or delete a file

You can’t rename or delete a file in Backend › Files.
