A well-constructed and consistently applied file naming convention and organization structure for your data will save you (and your colleagues) from frustration and wasted time. These practices will help you and collaborators identify and locate the correct files when you need them.

File Names

File Naming Conventions

  • Create meaningful names relevant to content, independent of location
  • Avoid very long file names
  • Use underscores (this_is_the_file_name) or “camel case” (ThisIsTheFileName) for separating terms
  • Use one of these date formats to facilitate sorting:  YYYY_MM_DD, YYYY-MM-DD, or  YYYYMMDD
  • Consider the potential number of files and include place holder digits in the name to facilitate sorting (e.g., for up to one hundred files, begin with …001…)
  • Avoid using spaces and special characters, i.e. ~ ! # & @ ( ) { } [ ] ‘ “ | % $ ; ^
  • Include versioning where needed
  • Be consistent

Example: Survey21 _Smith_2015_06_01.txt — a survey in a text file with participant 21, conducted by Smith on June 1st, 2015.

File Renaming
