Hello,
Thank you for reaching out and describing the issue you're experiencing with Excel files being saved under numeric names in the tmp.driveupload folder.
I understand how concerning it can be when files appear to disappear from their original folders or are renamed unexpectedly. This behavior may be related to how temporary files are handled during autosave or upload processes, especially when working with cloud storage or syncing tools.
To help mitigate this issue, I recommend the following steps:
- Check your sync settings in OneDrive or any other cloud service you’re using to ensure files are being saved to the correct location.
- Avoid working directly from temporary folders such as
tmp.driveupload, as these are typically used for intermediate storage during uploads or edits. - Save files manually to your intended folder before closing them, especially if you notice the filename has changed.
- Ensure your Office apps and cloud sync tools are up to date, as updates often resolve file handling issues.
