if you move you will break any registry and other connections. you can uninstall then reinstall within the folder.
After installing a program or game, is it safe to change the folder name in the ProgramFiles(x86) dir.? For example, I have two games installed, both made by the same company, Sierra Ent. One is in a folder titled "Sierra" and one is in a folder titled "Sierra Entertainment." I want to group these. by moving the game folder out from Sierra and having them both in Sierra Entertainment folder. If i do this, and I want to uninstall the game later, will it be able to locate it under "Uninstall a program?" If i have moved the folder after installation, will it mess ANYTHING up, or am I safe to do this? Sorry if this is a stupid question
