Welcome Ruth Sandon,
Thank you for posting on Microsoft Q&A.
From the screenshots, it appears that File Explorer may have changed how it is displaying your files. The names such as Birthdays and Deaths, Donation Process, and Ruth's Medical suggest these are likely your original files and folders, but Windows is now showing some items with their file extensions or with generic icons instead of their usual appearance.
To help determine what happened, could you please provide a little more information?
- Did this change occur after a Windows update, OneDrive sync change, or system restart?
- When you right-click one of the affected items and select Properties, what is shown next to Type of file?
- In File Explorer, select View > Show > File name extensions. Does enabling or disabling this option change how the files appear?
- Are the files still opening normally when you double-click them?
As a quick check, please also try:
- Open File Explorer.
- Select View > Show > Hidden items
- Then select View > Show > File name extensions
- Compare the affected files with the files that still appear normally and let us know what you see.
Once I know the file type shown in Properties and whether the files still open, I can narrow down whether this is a display issue, a file association issue, or a problem related to the folder contents.
I look forward to your update.
