The undo file-frame partial-file-detection enable command disables the function.
By default, the FW does not restore incomplete files.
When interworking with a sandbox, the FW restores complete files and sends them to the sandbox for detection. To enable FW to send incomplete files to a sandbox for detection, run the file-frame partial-file-detection enable command to enable the FW to restore incomplete files. Enabling the function compromises device performance. Therefore, you are not advised to enable the function in normal cases.
