![]() The Copy Features tool lets you select any or all of the features in the featureclass if it is a feature layer with a selection applied to it. The Feature Class to Feature Class tool lets you map fields, but restricts you to an SQL query to export any type of subset of features. Both tools will create a new feature class, whether with a new name, or if you have the geoprocessing setting correct, by overwriting an existing feature class. There are pros and cons to each approach. Copying the features means taking all of the attributes as well. Here, the focus is on taking a subset of features from a layer and copying them and all their attributes to a new layer. On the other hand, the Copy Features tool is working at the individual Feature level. You can choose a subset of features to copy over, but the emphasis is on the layer structure itself. This means that you have control over the structure of the new featureclass, including adding and deleting fields. A new feature class is going to be created. The Feature Class to Feature Class tool is working at the Layer level, meaning that regardless of the features selected, it treats them as a whole. The most basic difference is the level at which each of the functions are working.
