Use capital letters to delimit words

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.

Example

Correct file names
RiskManagement.rtf
RAEInstructions.html
Incorrect file names
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, and by using capital letters to differentiate between the words the file name is still readily recognisable.
