How to not separate pictures and videos in File Explorer?

Hi.

If Date Modified doesn't show on the options when you choose Sort by, we suggest that you perform this steps:

• In File Explorer, select the folder you want to have changes with.
• Right-click and select Sort by.
• Select More, then check if the Date modified option has a check mark.
• Click OK, then try to perform again the steps provided by Acelyn Alc.
