      Internet Legal Filename


      If you post a filename on your web site that uses an illegal filename, the results can be unexpected. Some browsers will produce a file not found error message and others won't know what to do with it.

      Here are some characters that should not be in a filename: !@#$%^&*,+' and we discourage perens ( ), spaces, and never more than a single period.

      See the examples below to understand what is and is not an internet legal filename.

      Internet illegal filenames (bad)

      • Annual.Report.doc (has 2 periods, should only have 1 before the three-letter suffix)
      • Third Quarter Annual Report#3.xls (has spaces and a hash # sign)
      • NewMonkeySuit!.pdf (has an exclamation point)
      • somedocument (missing the period and three-letter suffix)
      • Jane@the-summit.jpg (has @ sign)

       

      Internet legal filenames (good) here are the above filenames corrected.

      • Annual-Report.doc
      • Third-Quarter-Annual-Report-rev3.xls
      • NewMonkeySuit.pdf
      • somedocument.jpg
      • Jane-at-the-summit.jpg
