File formats are a standardized form in which data are coded so that a software program can read and interpret those data. As technology changes over time, some hardware and software may become unsupported and obsolete. During your research project you may use different formats to collect and analyze, and share your data. Even if some of your working formats aren't ideal for long-term preservation and accessibility, keep copies of them for data reproducibility.
File naming conventions are a set of agreed upon rules for naming files. Consistently structured files help you automate your workflows, find your files, and keep track of different versions of your files. Documentation about your file naming convention should include rules, any codes or abbreviations used, and examples.
