RAR is a well-known proprietary Archive file-format which got introduced to the world in 1993, since then it has been a very popular choice for data-compression, error-recovery and file-spanning. The GUI frontend for this file-archiver utility for Windows was named Winrar which is still a wildly popular application to create and view archives in RAR or ZIP file formats, and also unpack a whole bunch of other archive file formats.
The interesting thing here is that, WinRAR is distributed as a ''try before you buy'' software and the user is given a "free trial" for 40 days. BUT, most of you know that you can continue using it for free even after the 40 day Trial period ends. Want to know why? This video has got all your questions answered.
The WinRAR's infinite 40-day trial has given birth to whole range of entertaining MEME's as shared here.
