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
