Renames or moves a statics folder with everything inside. The bundle descriptions of the files inside follow it, the built bundles are not rebuilt.

The Right

“Direct access → Development → Modify data” (AGENT_ENGINE_DEV_WRITE).

Parameter	Type	What it is
`path`	string	what the folder is called now
`new_path`	string	what it will become

One call changes one thing:

the same parent, a new name — the folder is renamed;
another parent, the same name — the folder is moved. Any statics or images folder will do, including one in another template group.

The group’s own statics/ is the root: it cannot be renamed or moved.

{"path": "./../templates/default/statics/banners",
 "new_path": "./../templates/default/statics/promo", "bundled": 2}

Field	What it is
`path`	what the folder was called
`new_path`	what it is called now
`bundled`	how many of the files inside had a bundle description. If it is more than zero, the bundles are not rebuilt — see “Statics”

Answer	When
`No such folder in the statics tree: … engine_map_tree lists the folders under dirs.`	the folder is not among the statics folders
`… is the statics root of a template - it cannot be renamed or deleted…`	this is the group’s `statics/`
`… is not a folder of the statics tree.`	the path lies outside the group’s statics folder
`One act at a time: …`	`new_path` changes both the parent and the name
`No such folder: … engine_map_tree lists the folders of both trees under dirs.`	the new parent is not among the statics and images folders
`A folder cannot be moved inside itself.`	the new parent lies inside the folder itself
`Folder already exists: <name>`	a folder with this name is already in the new place
`new_path is the same path - nothing to change.`	the path does not change
`The last part of new_path must be a plain name.`	the new name holds `..`
`path is required…`, `new_path is required…`	one of the paths is not named
