+  Here is some of the files that Tracker uses during its operation,

+
+  * "~/.local/share/tracker" is used for non-expendable content,

+  * "~/.cache/tracker" is used for the expendable indexes and

+    purpose of the ".cache" - its more a permanent tmp directory than
+    sys tmp but can be deleted if more disk space is needed).
+
