To check your storage, right-click on the OneDrive icon in your taskbar > More > Settings.
Click the Account tab and you will see how much storage you have used.
If you are running out of space, try to delete the old files that you don't need to free the space. Provided that all of your files are important, you can transfer the files to other devices or upgrade your account to gain larger storage space.

Solution 4: Keep the Path Short
According to the OneDrive official documentation, the path with the filename and extension should be less than 400 characters. Thus, to avoid syncing problems, keep the folder and file names short.

If your OneDrive folders are not syncing or lag during upload, it might be affected by the internet connection speed. When you are syncing large files, you'd better do upload them in a Wi-Fi environment.

Click Edit to change all permissions to Allow.
Click Advanced > check Replace all child object permission entries... > Apply.
