Windows 7: I deleted my .dat file extention, will it still work if I re-create it

I deleted my .dat file extention, will it still work if I re-create it

So, I was having problems with my .dat file type icon, and in frustration trying to get rid of the icon and start all over again, I deleted the file type in the registry.

Will this cause problems in the future, even though I re-added it in the registry? I don't see any problems with them right now, but I didn't know if I might have troubles in the future due to this.

To change the icon, you are to change the program association for .dat file.

If you add it back, there should not be any problem.
