Rule 3

Use capital letters to delimit words, not spaces or underscores

Avoid using spaces and underscores in file names. Some software packages have difficulty recognising file names with spaces, this can be a particular difficulty for files when they are published on an external website, so it is best to avoid using spaces. Using underscores and hyphens in your file names increases the length, which is incompatible with rule 1.

Where capitalised acronyms are used in file names the acronym should appear in capitals and the first letter of the following word should also be capitalised.

Rule 3 Example
	Correct	Incorrect
File name	RiskManagement.rtf RAEInstructions.html	Risk_management.rtf Risk management.rtf RAE_instructions.html Research Assessment Exercise instructions.html
Explanation	Removing the space or underscore reduces the length of the file name, but by using capital letters to differentiate between the words the file name is still readily recognisable.
