+
+There are two things, filebundlestore and index
+  $ ls ../repo/.hg/scratchbranches

+
+filebundlestore stores the bundles
+  $ ls ../repo/.hg/scratchbranches/filebundlestore/a4/c2/
+  a4c202c147a9c4bb91bbadb56321fc5f3950f7f2
+
+index/nodemap stores a map of node id and file in which bundle is stored in filebundlestore
+  $ ls ../repo/.hg/scratchbranches/index/
+  nodemap
+  $ ls ../repo/.hg/scratchbranches/index/nodemap/
