Why is One of My OneDrive Folders Not Syncing?

 

I have a folder (say folder "A") on my PC that contains many subfolders (say folders "B"), and these subfolders contain many files. I dragged folder "A" to the OneDrive window. It appeared to sync. When I look at OneDrive, after the sync has apparently finished, folder "A" and all the folders "B" are listed. In some of folders "B", the files are also synced, but in MANY of folders "B", they are NOT.

6 Useful Tips to Fix OneDrive One File Not Syncing Issues

OneDrive's sync process could be interrupted if you exhaust your local storage or reach the maximum available space in the cloud. This can be particularly problematic when dealing with substantial data volumes or when storage space is limited. All you need to do is to increase OneDrive storage space, for example, by deleting useless files or upgrading your OneDrive account.

Or, you can go to the OneDrive Manage Storage page, see what is taking up your OneDrive storage, and make room by removing useless large files/folders.

Check Cloud Storage

Way 3. Update OneDrive

OneDrive typically automatically updates to newer versions when you update your Windows operating system. However, if there are issues with the update process, your OneDrive software may remain outdated. So ensure that you are using the latest version of OneDrive.

If you suspect that your OneDrive is not updating correctly, it is advisable to manually uninstall the outdated and download the latest OneDrive version to resolve the issue your OneDrive is not syncing.

Way 6. Check the File Path/File Size/Filename

File path, file size, and filename all have limitations when you sync files to OneDrive.

How to fix the limitation of a file path:

You have to notice that your file path should not exceed 400 characters. Having multiple sub-folders or a long file path can indeed lead to OneDrive folder not syncing issue. So navigate to your OneDrive folder on your computer, if you identify sub-folders with long or complex names, consider renaming them by right-clicking and selecting Rename to create a shorter file path.

How to fix the limitation of file size:

OneDrive has a file size limitation depending on the web browser you use and allows users to upload files up to 250 GB in size per individual file, so before attempting to sync a file, check its size. If you have a file that exceeds this limit, consider reducing its size.

How to fix the limitation of a filename:

OneDrive has a limit of 255 characters for file or folder names. Additionally, there are certain characters that have special meanings or are not allowed in file and folder names in OneDrive. These restrictions are in place to ensure compatibility and prevent naming conflicts. Here's a summary of those restrictions:

(Leading and trailing spaces in file or folder names also aren't allowed.)
