Take the pop culture acronym challenge
Techies use LRU to mean "least recently used." Most often, this acronym refers to the files on your computer that you've accessed least recently. For example, a system scanning program may allow you to sort your files by LRU or MRU (most recently used).
However, LRU can also refer to lesser-used files you have languishing on a portable hard drive or in the cloud, or other last-used data. And, in some rare cases, you may even encounter LRU used in a non-technical context.
