Auto Rename 4+

Auto Rename app provides assistance finding and renaming files/folders containing invalid character(s) in their name; see OneDrive and SharePoint restrictions and limitation article. For the user convenience, an archive, log file, and error options are available to save changes being made or review possible permission conflicts.

OneDrive reserves the use of characters that have special meaning on filename. For example, if a file or folder you are trying to upload to OneDrive contains an invalid character(s), it will fail to upload to Microsoft cloud servers. Thus, the sync process fails to continue. Alternatively, one can manually find and rename files or folders with invalid character files before syncing to OneDrive and/or SharePoint when the file transfer process fails to upload.

In addition, app provides option to list files whose name length is between the range of 50 to 300 characters long. Feature is useful as the file path cannot contain more than 400 characters when syncing files in OneDrive. For example, the length of the OneDrive root folder plus the relative path of the file cannot be more than 520 characters.
