(add) icon beside its heading. In the dialog that opens, enter a name for the collection and confirm (or type the name in the collection field and press **Enter**). ## Assign a collection at upload In the **Upload Manager**, use the **Add to Collection(s)** panel on the right to assign every file in an upload batch to one or more collections. 1. Trigger your upload — the **Upload Manager** opens. 2. In the **Add to Collection(s)** panel, tick the collections you want to assign. 3. Click Upload Now

. Every file in the batch is added to the selected collections on arrival. ## Add documents to a collection after upload Select documents with their checkboxes, click Edit Collections

in the bulk-action toolbar, tick the collection, and click Apply

. A document can belong to several collections at once. To work with just one collection, click its name in the sidebar to filter the matter to that collection. You can then act on just those documents — for example, select them and re-run analysis from the **Review** tab, or [export the subset](/how-to-guides/export/export-filtered-subset.md). See [Folders, labels, and collections](/reference/folders-labels-and-collections.md) for how collections behave and for the other ways to add documents to one. ## Clone a collection To reuse an existing collection as a starting point, hover over one of your collections in the left sidebar and click the

**Clone collection** icon. BriefTech opens the collection dialog pre-filled with the name "Copy of …" so you can rename it and confirm. The new collection starts as a copy of the original — its documents, its index and bundle/export settings, and any per-document headings — and is independent afterwards, so later changes to one do not affect the other. Cloning is offered on the collections you created, not the built-in **All** or **None** views. ## Related

GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://help.brieftech.ai/how-to-guides/organise/group-documents-into-collection.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
