+Sanitize filenames
+^^^^^^^^^^^^^^^^^^
+
+This command allows to automatically rename files not matching the current file naming constraints,
+for example after enabling the :ref:`Windows compatible filenames <windows_compatible_filenames>`::
+
+ Usage:
+   files:sanitize-filenames [options] [--] [<user_id>...]
+
+ Arguments:
+   user_id                                 Limit filename sanitizing to files given user(s) have access to
+
+ Options:
+      --dry-run                            Do not actually rename any files but just check filenames.
+  -c, --char-replacement=CHAR-REPLACEMENT  Replacement for invalid character (by default space, underscore or dash is used)
+
+When running this command without parameters it will scan all files of all users
+for filenames not comply with the current filename constraints and try to automatically
+rename those files.
+Invalid characters will be replaced by default with either a space, underscore, or dash
+depending on which characters are allowed.
+If your constraints forbid all of them, then you have to provide an character replacement
+yourself by specifying the ``--char-replacement`` option.
+
+The ``--dry-run`` option allows to perform the sanitizing without the actual renaming,
+this is useful for estimating the execution time and to get an overview on what renaming
+actions will be performed.
