Having the relevant date associated with the file is essential. Although many operating systems store date information with the file, as users move the file among folders and computers, and as the file is re-saved as revisions are made, the dates change. A file could have dates that do not make sense to its original creator.
The best way to prevent confusion is to include the relevant date (the date that the file was created or revised) in the file name itself.
Some workgroups might find it more useful to have the date at the start of the file name, while others might prefer it at the end. Either way, the date is a useful sorting tool when files are organized. Just be sure to keep the structure consistent.
The best way to list the date is based on an international standard: ISO 8601. This standard specifies numeric representations of date and time to be used in electronic format. The international standard date notation is:
YYYY_MM_DD
or YYYYMMDD
For example, April 5, 2011, is written as 2011_04_05
or 20110405
.
This format allows ease of sorting and comparing files by date and prevents confusion with other date formats (especially in other formats that use just two digits for the year).
For example, the meeting minutes of the State Records Commission from October 26, 2016, could be 2016_10_26_SRCMinutes
or SRCMinutes_2016_10_26
.
