Configuring public links

Note: The classic M-Files Desktop in M-Files January '24 Update and later no longer refer to public links. Instead, these links have the name visitor link for anyone. This means that user interface uses the new name "visitor link for anyone", but the links still use the configuration of public links. The classic M-Files Web still uses the term "public link".

Important information

The registry and Custom Vault Data settings given here can restrict sharing also in the new M-Files Desktop and M-Files Web. If sharing issues occur, make sure that the settings are not in use.
A public link created by a user will work as long as these requirements are met:
- The user's account is enabled.
- The user has at least read permissions to the document.
For security reasons, the link will stop working if either requirement is not met. To share documents with a large number of people without access to M-Files, consider these alternative sharing methods:
- M-Files Hubshare offers more control and security.
- Anonymous vault access lets users access a vault without credentials.

Before you start to configure public links, make sure that these prerequisites are completed:
