Hello,
Thank you for posting in Q&A forum.
According to your description, this issue may be caused by some cache files or other system issues. Here are some suggestions to help you solve this problem:
You can try logging back into OneDrive and find the option to clear cache in OneDrive settings. Sometimes, OneDrive may take some time to synchronize and free up space after deleting files.
For temporary files on drive D, first make sure that your disk has not released any space. You can right-click on the D drive in the Explorer, select "Properties", and then check the disk's usage to ensure that 90GB of space has not been released. After confirmation, you can try using the system's built-in disk cleaning tool to clean these files:
Type "Disk Cleanup" in the Windows search bar and open the tool.
Select the disk you want to clean (in this case, the D drive).
Check the options such as "Temporary Files" and then click "OK" to clean up these files.
I hope these suggestions are helpful to you! If you need more help, please feel free to let me know.
Best regards,
Jill Zhou
