Disable File Transfer

Disabling in-meeting file transfer prevents any virus-infected or undesired files from being shared with other participants.

Sign in at https://zoom.us, click Settings > Meeting > In Meeting (Basic).

Scroll down to File Transfer, and disable by clicking the switch off.

If file transfer is necessary, selecting only allow specified file types can help improve security by specifying which files are permitted, by the extension type.  Examples include graphics (.jpg, .png), MS Office documents (.docx, .pptx), or archived files (.zip, .7z).  Avoid permitting any executable and script files (.exe, .bat, .vbs, .js, .ws, .reg), which could contain malicious code.
