The icons in the working copy view have a small overlaid icon which describes the current state of the resource in the working copy. These state icons are:
Unversioned - The resource marked with this symbol is not under version control. This is how new files are represented when they are created or copied from the file system.
Added - This resource has been added to version control but has not been committed. This state is obtained after issuing an Add command on an unversioned resource.
Added with history - This resource has been copied with history. This state is obtained by copying, moving or renaming a resource from the working copy.
Modified - The resource has been locally modified since the last update. This is obtained after editing a file and making changes.
Deleted - This resource has been deleted from the working copy. This state appears after deleting, moving or renaming files with Subversion.
Missing/Incomplete - This resource is in an inconsistent state. If it's missing, it means it has been deleted from the file system without Subversion's knowledge. If it's incomplete, a check out or update action has probably failed or has been interrupted before finishing. A directory in such a state must be restored with an update action before any other action can be performed.
Conflicted - This resource has conflicting changes. A resource can be in this state after an update, if it was modified both locally and on the repository and the modifications were overlapping.
External - This indicates a mapping of a local directory to the URL of a versioned resource. It is declared with a svn:externals property in the parent folder.
Normal - A resource with no overlaid icon is an unmodified resource under version control.
Grayed - A resource with a grayed icon but no overlaid icon is an ignored resource. It is obtained with the action Add to svn:ignore.
