+## Preserve Air During Schematic Load
+`//load` only writes non-air blocks in a saved WorldEdit schematic. To get around this the `//allocate` command was created so that users could set the target area to air before the new nodes were written. The following command applies this work flow (replace `<file>` with the name of your schematic before using the command):
