Troubleshooting File and Folder Upload Issues

If you are having trouble uploading files or folders, please try the following troubleshooting steps.

1. Try clearing your browser's cache. If this does not resolve your issue please proceed to the next step.
2. Verify that the file's name is valid. Box only supports file or folder names that are 255 characters or less. File names containing non-printable ascii, "/" or "\", names with leading or trailing spaces, and the special names “.” and “..” are also unsupported. 
3. Make sure you are uploading files smaller than the maximum for your account type. Crossland's max file size is 5GB.
4. Within the 'Upload' drop-down menu there are two options:
   'Upload Files' or 'Upload Folders'. Try uploading with the 'Upload Files' method instead of 'Upload Folders', or vice versa.
   
5. Please ensure your web browser is the latest version of Internet Explorer, or Chrome.
6. Clear your Java Cache. Follow steps here: http://www.java.com/en/download/help/plugin_cache.xml
7. Check your network connection to Box. If connected to the internet with a wireless card, check to see if the connection to the internet drops intermittently. If this is the case, we recommend the Upload Folders method.
8. Proxy servers may sometimes cause failed uploads. If you see the error message: An error occurred with the upload. Please refresh the page and try again. Please contact your IT department or Help Desk and ask them to check your Java security settings or proxy configuration.
