Common Issues and Solutions
ISSUE: File will not sync or upload. Special characters, such as the ones below, appear in file names.
~ " # % & * : < > ? / \ { | } .
- SOLUTION: Rename files or folders with these characters, or with long file or folder names.
ISSUE: File will not upload because it start or ends with a blank or empty space character.
- SOLUTION: Remove the blank or empty space from the beginning or end of the file name (or before the period in the file suffix).
- A space character is the invisible character created when you press the space bar on your keyboard. (The Tab and Enter/Return keys on your keyboard can create invisible characters too, especially in Word documents or text files.)
ISSUE: If the file or folder name is 256 characters long or longer, the file will probably not upload.
- SOLUTION: Rename these files or folders to shorten their names.
ISSUE: If a file or sub-folder is buried deep within multiple other folders and sub-folders, and the entire file directory path name (for example: C:/folder/sub-folder/sub-sub-folder.../file.docx) is larger than 256 characters or more, the file or sub-folder will probably not upload.
- SOLUTION: Navigate to those deeply buried or nested files or sub-folders on your computer, and then try uploading them to directly to the OneDrive web portal. Avoid folder structures that are more than 3 levels deep.
ISSUE: Individual files cannot be 10 GBs in size or larger. (Folders can be, but not individual files.)
- SOLUTION: Contact us. See "Additional Assistance" area below. We likely will need to rely on CrashPlan to keep these files backed up on your computer.
ISSUE: Some internet browsers may not let you upload files that are 2 GBs or larger.
- SOLUTION: Try Chrome. Drive has 5 TB file upload limit. Or contact us for assistance. See "Additional Assistance" area below. We likely will need to rely on CrashPlan to keep these files backed up on your computer.
