# Knowledge Base

To limit the file types that can be uploaded through Bynder and to prevent malicious files from entering the Asset Bank, you can set a special security check. In that way only the files with the specified extensions can be uploaded.

The system first scans the mime type of the file so even if the user changes the file extension, the file will fail the security check. Currently, there is no check for files uploaded with the Version Updater and Mass Uploader.

Contact your Bynder Customer Success Manager if you would like to have this feature enabled for your portal as well as for more information and help with the setup.

The below mime types can be whitelisted:

### Note

Plain text documents, such as .TXT and .SRT cannot be whitelisted.
