what is wrong with a video file when it has a x mark on it instead of a check mark

A red X on a video file usually means the file is having a sync or availability problem , not that the video itself is necessarily broken. In Windows, especially with OneDrive, a red X commonly means the file could not sync correctly or the cloud copy is having an issue.

What it can mean

• The file failed to sync to cloud storage such as OneDrive.

• The storage account may be full, so new changes cannot upload.

• The file may be stuck, unavailable offline, or have a permissions/problem state in the folder.

What to check

1. Look at whether the file is stored in OneDrive or another cloud-synced folder.

2. Check if your cloud storage is full.

3. Try opening the video locally, or move it to a normal local folder like Desktop or Videos.

4. If it is OneDrive, pause and resume sync, or unlink and re-add the account if needed.

Simple rule of thumb

• Green check mark = synced and available.

• Red X = something went wrong with syncing or access.

If the file is on your computer and not in a cloud folder, the red X may come from the app you’re using rather than the video itself.
