IPA: /ˈdeɪtəfaɪl/
KK: /ˈdeɪtəˌfaɪl/
A file on a computer that holds information for use by software or systems.
The software requires a datafile to function properly.
Datafile → It is formed from "data" (from Latin "datum", meaning something given) and "file" (from Old French "fil", meaning a thread or line). The word "datafile" refers to a file that contains data or information organized in a specific format.
Think of 'data' as something 'given' and 'file' as a way to organize it, so a datafile is a way to organize given information.
