.POP File Extension

Game file used by Team Fortress 2, a multiplayer first-person shooter game; used by the Mann vs. Machine (MvM) game mode and controls what robot classes should spawn as well as how frequently they should appear.

POP files can be edited with a text editor. They are commonly edited for customizing the MvM game conditions.

Graphic file used by Samsung MP3 players such as the U3, U5, and U6; stores a bitmap image of a "Popcon," which is a small animated character, similar to a Tamagotchi pet; used for displaying the Popcon while starting up the MP3 player, playing music, or browsing menus.

POP files are 24-bit RvB (Red versus Blue) .BMP graphics that are 40x40 pixels in dimension. Four POP files make up the total animation frames for the Popcon. The files are named MyPopcon_1.pop, MyPopcon_2.pop, MyPopcon_3.pop, and MyPopcon_4.pop. These files reside in the \​U5\​Popcon\​ directory of the MP3 player and can be replaced with new graphics by connecting the device with a PC.

NOTE: The graphics in POP files can be viewed by renaming the ".pop" extension to ".bmp" and then opening the file with any image viewer.
