Manage Your Research Data: File Formats & Naming

This guide provides a primer on the fundamentals of data management.

File Naming & Formats

File Naming Best Practices

File naming conventions make life easier! It helps you find your data, helps others find your data, and helps track which version of a file is most current

  • Use descriptive names that identify content and version without being too long (less than 25 characters).
  • Name may also indicate researcher, equipment, lab, or date. This varies by the needs of the project.
  • Avoid special characters like ! @ # $ % ^ & *.
  • Add versions or dates into file names
  • When using dates, use numerals and begin with the year and month. Example: 1/26/21 would be 20210126. 

File Format Best Practices 

Consider using file types that can be opened without proprietary software. These options include:

  • Video images: MOV, MPEG, AVI, MXF
  • Text: XML, PDF/A, HTML, ASCII, UTF-8
  • Sounds: WAVE, AIFF, MP3, MXF
  • Containers: TAR, GZIP, ZIP
