Hi ew we,
Thanks for reaching out to Microsoft Q&A Forum. I understand that after moving files and apps between the C: drive and D: drive, your personal folders such as Videos now appear mixed with system or app-related folders like app data or OneDriveTemp, causing your files to look disorganized.
Please make sure you already tried the Q&A Assist steps. In addition, please try the following.
Before moving forward, I’d like to narrow this down a bit:
1, Did you move your Videos or other user folders by right-clicking the folder, selecting Properties, and using the Location tab?
2, Are you currently signed in to Windows with a personal Microsoft account or a local account?
In the meantime, you can try these steps:
1, Check the actual location of the Videos folder
- Open File Explorer
- Right-click the Videos folder under This PC
- Select Properties, then open the Location tab
- Confirm whether the path points to a standard user folder or directly to the root of the D: drive
2, Restore the default Videos folder location
- In the Location tab, select Restore Default
- Apply the change and allow Windows to move files if prompted
3, Review the root of the D: drive for misplaced folders
- Open This PC and double-click the D: drive
- Look for folders that appear to be system-related or app-related
- Do not delete them yet; only note what appears to be out of place
4, Verify where new content is being saved
- Open Settings
- Go to System, then Storage
- Open Advanced storage settings and select Where new content is saved
- Ensure documents, videos, and other content types are set to the intended drive
5, Reinstall any apps that were manually moved
- If any apps were moved by cutting and pasting their folders between drives
- Reinstall those apps so Windows can recreate their folders correctly
6, Restart the device and recheck folder structure
- After restarting, open Videos again
- Confirm whether system or temporary folders are still appearing there
