Hello,
Thank you for posting in Q&A forum.
Windows 11 will not automatically copy video files from USB flash drives. This situation may be caused by other reasons. We suggest that you try the following inspection methods:
Check the automatic backup settings of your computer to ensure that no automatic backup functions related to USB flash drives are enabled. You can search for "backup" in Windows settings to access backup settings.
Run security or antivirus software to scan your computer for any malicious software or viruses. These malicious software may cause files to be copied or transferred to other places.
Check your File Explorer settings to ensure that hidden files and file extensions are not enabled. Sometimes, files may be hidden or displayed as different file types, making it difficult for you to find them.
Check other applications and services installed on your computer to see if there are any settings related to file copying or transfer. Some applications may automatically copy files to specific locations.
I hope this information is helpful to you! If you have any other questions, please feel free to ask.
Best regards,
Jill Zhou
