# File upload failing

If you see a warning when adding a file, the cause is usually the file type, size, or your organisation’s storage quota. Follow the steps below according to the warning message.

- Project manager

- Project Member

- Customer

## Steps

- Read the text of the warning that appears at the bottom of the screen.

- Apply the solution for that warning from the list below.

- Re-add the file using Add file.

## Solution based on the warning

- "This file type cannot be added for security reasons." Executable files are not accepted. You can upload the file inside a .zip archive.

- "File too large": The limit is 250 MB per file, or 50 MB for the Customer role. Split or compress the file.

- "Your storage is full." Your organisation’s DBLinx storage space is full. Your organisation administrator can increase the space via the DBLinx tenant panel, or unnecessary files can be deleted.

- "File failed to upload" or "File storage currently unavailable": Connection may have dropped. Check your internet connection and try again after a few minutes.

## Add File button not visible

- If you have the Observer role in the project, you can open files but not add them. Ask your project manager to change your role.

- If you have the Customer role, you can only add files to tasks open to you; you cannot add them to the project’s Files tab.

> Tip Do not close the page while uploading. Incomplete uploads do not appear in the list; simply re-add the file.
