|The DITA documentation process|
Using an organisation-wide, well-documented file naming and folder structure convention will improve the usability of the authoring process for DITA authors, especially those working in a team.
Use descriptive folder and file names. Use .dita as the file extension for topic files, and .ditamap for ditamap files. File names are case-sensitive, and lower case file names are preferred. Prefix topic names with a letter corresponding to their information type.
