→Original Files
In BaseX, all updates are performed on database nodes or in main memory. By default, update operations do not affect the original input file (the info string "Updates are not written back" appears in the query info to indicate this). The following solutions exist to write XML documents and binary resources to disk:
* Updates on main-memory instances of files that have been retrieved via {{Code|fn:doc}} or {{Code|fn:collection}} will be propagated back to disk when the if {{Option|WRITEBACK}} option is turned on. This option can also be activated on [[Command-Line Options#BaseX Standalone|command line]] via <code>-u</code>. Make sure you back up the original documents before running your queries.
* Functions like <code>[[#fn:put|fn:put]]</code> or <code>[[File Module#file:write|file:write]]</code> can be used to write single XML documents to disk. With <code>[[File Module#file:write-binary|file:write-binary]]</code>, you can write binary resources.
* The [[Commands#EXPORT|EXPORT]] command can be used write all resources of a databases to disk.
