Whitelisting of file extentions in sharepoint folder
Hi If I have shared a folder with multiple people in SharePoint and I expect only certain file types to be uploaded into my SharePoint's shared folder (e.g. docx,xlsx, ppt, txt) and block all other types of file extensions (e.g. 7zip,rar,exe, dll) so that I can reduce the risk of someone uploading a malicious or an encrypted file, or some kind of source code. I don't want to go by the way of blocking or blacklisting file extensions as that would be too extensive an exercise than whitelisting. Do we have such options in SharePoint that allow us to control the file extensions that can be uploaded? Just want to narrow down the risk from a security perspective. Thanks SAM
