Large research projects can generate hundreds of data files. Short descriptive file names and a simple file hierarchy make these files easier to navigate and locate.  Set up conventions for your project, document them for all team members, and be consistent.

Recommended conventions:

Denote dates in YYYYMMDD format

DO: Use 20180403

DON’T: Use 04032018

BECAUSE: Computers sort YYYYMMDD in chronological order.


Use a short unique identifier (e.g. Project Name or Grant #)


DON’T: Centre for Hip Health and Mobility

BECAUSE: Short filenames prevent the need for side scrolling and column adjustment.


Include a summary of content (e.g. Questionnaire or GrantProposal) as part of the file name

DO: FileNm_Guidelines_20180409_v01.docx

DON’T: FileNm_20180409.docx

BECAUSE: Files will be easier to find.


Use _ as delimiters. Avoid these special characters: & , * % # * ( ) ! @$ ^ ~ ‘ { } [ ] ? < > –

DO: FileNm_Guidelines_20140409_v01.docx

DON’T: FileNm Guidelines 2014 04 09 v01.docx

BECAUSE: Different computer systems handle special characters differently – filing order, etc.


Keep track of document versions either sequentially (e.g. v01, v02,) or with a unique date and time ( e.g. 20140403_1800)

DO: FileNm_Guidelines_20140409_v01.docx

DON’T: FileNm_Guidelines_20140409_Review.docx AND FileNm_Guidelines_20140409_Investigation.docx

BECAUSE: Two years from now, you won’t remember what you meant.

Make folder hierarchies as simple as possible

DO: F:/ Env/LIBR/DataMgmt_FileFormats_20140409_v01.docx

DON’T: F:/Environment/Library/Woodward/Data/Education/Materials/Draft/2014/04/-DataMgmt_FileFormats_20140409_v01.docx

BECAUSE: Complex folder hierarchies are harder to navigate and offer more opportunities for filing errors. System back-ups may take longer.
