Working set
Imagine if the Project Explorer contained a filtered view of resources in your project. I.e., a subset of it. E.g., a view that ignores the Test directory, and everything in it; but includes parts of another project within the workspace. If you could save such a view, it would essentially be a Working Set.
Path Variables
These are just like Environment Variables, but they apply to Eclipse, the Current Workspace, and the Current Project. Here are some examples.
ECLIPSE_HOME: C:\Program Files\eclipse\ WORKSPACE_LOC: A:\Documents\Eclipse\Projects\Practice PROJECT_LOC: A:\Documents\Eclipse\Projects\Practice\TestSphinxWiz
Workspace
Your workspace is a folder that contains a subfolder called “.metadata”.
Counter to what you might expect, the workspace folder doesn’t physically contain project folders. It contains them by reference.
