PPT files do not upload. Only PPT files.

Hi ​@Sandy2024, 

Welcome to Box Community, and we’d love to help! 

To resolve your upload error, we’ve outlined the troubleshooting steps that’ll help resolve the issue. 

Please follow the steps below: 

• Make sure that your web browser is the latest version of Chrome, Firefox, Safari, 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 0 (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
• If you see filenames containing .DS_STORE or starting with dot underscore as in: "._filename" this is caused by Mac OS X and is known as AppleDouble.
  • For an explanation how to clean each see these resources: 
    • https://www.techrepublic.com/article/how-to-disable-the-creation-of-dsstore-files-for-mac-users-folders/
    • https://en.wikipedia.org/wiki/AppleSingle_and_AppleDouble_formats

      • AppleDouble Example: If you have a file named MyDocument.txt, macOS might create a hidden companion file called ._MyDocument.txt.

• 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: 
  • Upload to Box Through Email
  • Email Uploads to a Folder Are Failing
• 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./

Hope it helps! 

Hello,

I've been using BOX for years, but since last week I can't upload .ppt files—everything else uploads fine. I tried different browsers and renaming the file, but no luck. .pptx works, so I’m guessing it might be a new restriction or bug.

Best Regard,

Reyans
