Required Editions

Available in: All Editions

Permission sets available in: Contact Manager, Professional, Group, Enterprise, Performance, Unlimited, Developer, and Database.com Editions

From Setup, enter User Profiles in the Quick Find box, and select Profiles.
Click Edit next to the user profile you want to change.
In the Administrative Permissions section, enable or disable the Select Files from Salesforce checkbox, and click Save.

Another option is to apply the permission in a permission set. Users who have this permission disabled are still able to upload files from their local drive. To apply the permission in a permission set, from Setup enter Permission Sets in the QuickFind box, then select Permission Sets. Edit the permission set and apply the Select Files from Salesforce permission.

Note The Enable Chatter permission on a user's profile can affect how files are uploaded. If your custom component doesn't use lightning-file-upload or lightning:fileUpload, users can still upload files even if Enable Chatter is turned off. You need to add your own rules to block file uploads if you don't want users to upload files.

If your custom component uses lightning-file-upload or lightning:fileUpload, users cannot upload files if Enable Chatter is turned off. You should make sure the Enable Chatter permission is set correctly to control who can upload files.
