Where do I put the DCM and LIB


If I want to add a symbol to my schematic. Where do I put the DCM and Associated LIB files for the part to my project and how.


You can put them wherever is convenient for you. How you add them to a project depends on what version you are using.


To add to what @bobc already wrote:
I would suggest to put the libs inside the project folder iff the library is poject specific.
Put it in some central place with all your other personal libs if it is not project specific.
