Have you ever had that nagging grey X on your files and folders and wondered what to do about it? This is something to be worried about as opposed to the green check mark.

A green check mark indicates that syncing with OneDrive went well, but a grey X means something is wrong with syncing, and you risk losing your files.

What does a grey X on a file mean?

The cloud is an excellent place for storing files, but sometimes you may encounter errors when uploading your files. One common error is the grey X on OneDrive files.

Windows’ default cloud storage is the OneDrive which allows users to back up their files. However, when your file was uploaded and the grey X appeared, there was an error during the upload process, and your file could not be saved.

In the worst-case scenario, it means that the file is corrupted. Then, if you try to open it, you will get an error message. 

Why is there a grey X on my files?

The most common reasons for this error are:

  • Limited storage space – You may have exceeded your storage limit. You may have to clear some storage space or purchase more.
  • File is too large – Some files are too large for OneDrive. For example, files over 2 GB can’t be uploaded directly to OneDrive. Instead, you may need a file compressor and try uploading again.
  • Failure in syncing – This could be because the file in question was never added or removed from your computer.
  • Changes on the file – If the file has been changed on your computer while offline but not on the cloud, this can cause the grey X to appear.
  • Third-party apps – If you have a grey X on a file, it’s probably caused by a shortcut app that has been blocked from accessing it because of an error in its code.
  • Interference from other cloud applications If you have more than one cloud application and have enabled all of them, you may have issues with the grey X.

How can I get rid of a grey X on my files and folders?

First and foremost, before any advanced troubleshooting, check the following:

  • Refresh the Desktop.
  • Disable any third-party shortcut applications.
  • Check the file size and compress it if needed, especially if you are getting the OneDrive is full error.
  • Ensure you are signed in to OneDrive and sync any pending files/folders.
  • Finally, restart your PC to clear out any temporary files.

1. Launch the file using another application

  1. Right-click on the file and select Open with then choose an alternative option.
  2. If the file opens, click Save as and see if the grey X disappears.
