Characters to Avoid in Directories and Filenames

http://www.mtu.edu/umc/services/web/resources/cms/characters-to-avoid.html

Do not use any of these common illegal characters:

# pound	< left angle bracket	$ dollar sign	+ plus sign
% percent	> right angle bracket	! exclamation point	` backtick
& ampersand	* asterisk	‘ single quotes	| pipe
{ left bracket	? question mark	“ double quotes	= equal sign
} right bracket	/ forward slash	: colon
\ back slash	blank spaces	@ at sign

Also, keep these rules in mind.

• Don’t start or end your filename with a space, period, hyphen, or underline.
• Keep your filenames under 31 characters.
• Most operating systems are case sensitive.
• Non-ASCII characters need to be escaped.

Example:

Bad filenames	Translates to
F&A Costs.html	F&A%20Costs.html
my PDF file#name.pdf	my%20PDF%20file%23name.pdf

Good filenames:

• F_A_Costs/index.html or F-A-Costs/index.html
• my_PDF_file_name.pdf or my-PDF-file-name.pdf
