# Browse a data-source import preview as a tree

`GET /datasources/import-preview/{preview_id}`

Lists one lazily-loaded level of a previously created import preview's unified file tree; each file is tagged valid/invalid/review. Pass `path` (relative to the business root, empty for the root) to list a folder's children, and `page_token` from a previous response to continue a large level. Folders may recur across pages and must be de-duplicated by path.
