Hi there, 

Welcome to Box Community and glad to assist! 

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

  • Make sure that your web browser is the latest version of ChromeFirefoxSafari, or Edge. An out-of-date browser can cause file upload problems.
  • Clear your browser's cache - If this does not resolve your issue, please proceed to the next step.
  • Verify that you are using one of our supported operating systems.
  • Check that the file 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. Box supports only Unicode Basic Multilingual Plane (BMP) characters in file and folder names.
    • The following reserved characters are not allowed:

      • < (less than)
      • > (greater than)
      • : (colon)
      • " (double quote)
      • / (forward slash)
      • \ (backslash)
      • | (vertical bar or pipe)
      • ? (question mark)
      • * (asterisk)
    • File/folder names are case-insensitive (no distinction between "a" and "A") and accent-insensitive (no distinction between "a" and "ă"). You can't have a file/folder titled with "Test" and "tèst" in the same directory as the file/folder name must be unique in each directory.
  • Verify that the file or folder's path on Windows machines is under the 255-character Windows limitation. Folder paths that exceed 255 characters may truncate the content's name before uploading to Box.
    • For example: file names will be shortened to the '8.3' convention and contain a tilde character '~': Exampl~1.PDF
  • Make sure you are uploading files smaller than the maximum for your account type. To determine your maximum, click on your initials in the top-right corner of the page and select Account Settings. Then, click on Account and your Max file size will be listed under Account Details.
  • Try uploading using the File upload method instead of Folder upload, or vice versa.
  • If using the Email Upload feature, then please review these for help: 
  • Files that are active like an Outlook PST file may have upload problems. Try copying the active file (i.e. *.PST) file to a separate file and upload the copy instead. 
  • Check your network connection to Box. If connected to the internet with a wireless card, try a wired LAN connection. Check to see if the connection to the internet drops intermittently. If this is the case, we recommend the Folder upload method.
  • Try temporarily disabling or configuring your firewall to allow Box as a trusted site. You may find that your anti-virus software includes a built-in firewall that is impacting performance. If you are attempting to access Box from an office location and experience upload issues, then please contact your IT administrator or internal Help Desk.
  • 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 proxy configuration.
  • For Download issues please see Common Issues with Downloading Files

Hope it helps!
