+[[JOSMImage(purge,48,link=,middle,margin-right=20)]] ''Keyboard shortcut'': **`Ctrl+Shift+P` ([wikitr:/Help/ExpertMode expert mode] only)**
+
+The purge action cleans up your data layer by removing the selected [wikitr:/Help/Concepts/Object objects] from the layer. However, in contrast to the [[JOSMImage(dialogs/delete,24,link=,middle)]] [wikitr:/Help/Action/EditDelete delete action], they **will not be deleted in OSM database** on the server when you upload your changes. 
+
+It is, as if JOSM completely forgets about these objects and they never had been downloaded.
+
+
+== Warnings ==
+=== Dependent objects ===
+When you purge a node of a way, that way cannot exist without its nodes, so it has to be purged as well. JOSM will give a warning in this case and lets you inspect the objects that need to be purged in addition to the original selection.
+
+The same holds, if you like to purge a new object (`id:0`) that is member of a relation. Members with a positive id can be purged without affecting the relation. Their status will be ''**incomplete**'' after purging.
+
+If you get this warning, you can safely proceed, but be aware that more objects are purged, than originally selected.
+
+=== Modified objects ===
+If you purge modified objects, these edits are lost. This can be intended, but you will get a warning in this case.
+
+
+== Clear Undo/Redo buffer ==
+This option is supposed to free resources (memory). But don't rely on it (yet). If you are short of memory, it is still the best option to [[JOSMImage(save)]] [wikitr:/Help/Action/Save save] the (partially purged) layer and reopen it in another instance of JOSM.
