As I already advised the file is related to PopCap Games
, a site for free online games such as Bejeweled
. It is an anti-cheat file.
Some Shareware program vendors incorporate time limit features in the installation routine which are created in the registry to keep a record of how many times a program may be used legally. This is done to prevent folks from using he program after the expiration period. Unfortunately, there are always a few folks who look for ways to circumvent such features so they can continue to use the program beyond that expiration date in order to avoid paying the vendor for using their product. Without providing specific details as to how all this works, all I will say is that the popcinfo.dat file is an additional safeguard to prevent folks from doing this.
If you are using a PopCap Game, then that program is responsible for creating popcinfot.dat. You can remove the game and that should allow removal of that file or leave it alone knowing its source.
