Describe in detail how to prohibit suspected uploads

In WFilter's "Application filtering", there is an intelligent filtering option to select "block suspected uploads of more than N bytes". As shown below:

The application filtering option based on the application feature library is limited to specific applications, such as shielding QQ files; but for the application protocols that are not in the application library, the shielding policy cannot be set directly. Unlike other filtering options, when enabled, WFilter automatically detects the size of uploaded data in each connection and forbids it as "suspected upload behavior" once the uploaded data exceeds the limit. Taking advantage of this option has the following benefits:

It can take effect for all application protocols.

Uploads that are not in the application feature library can also be prohibited.

Uploads on https sites can also be distinguished and blocked.

As shown in the figure below, uploaded attachments in https's web mail can be identified and disabled.

You can also block attachments posted by the forum.

The uploading behavior in QQ and Wechat uploading files can also be recognized.

One of the shortcomings of this option is that there will be some misjudgment, such as using Wechat video, video upload will also be determined to be suspected of uploading behavior and banned. If you want to allow video or some specified sites, you can activate it through "exception settings".
