Union

How to Add Union Using RcloneView

A Union Remote merges folders from multiple cloud remotes into a single unified folder. It is different from Combine:

  • Combine shows folders side by side.
  • Union merges multiple folders into one view.

Union is useful for:

  • Accessing data across remotes as if it were one folder.
  • Single-pane browsing and multi-cloud backup layouts.
  • Building a virtual filesystem without copying or moving data.

Create a Union Remote

Step 1 — New RemoteVirtualUnion

new remote add union

Step 2 — Enter Union details

Fill in:

  • Remote name: e.g., MyUnion.
  • Upstreams (Remote:Path): Each Upstream is one actual folder location.

Add the first Upstream by selecting a remote and folder:

union select folder first

To add another Upstream, click Add Remote and pick the next folder:

union select folder second

Add as many Upstreams as needed, then review the settings:

union input window

Click Add Remote to create the Union remote.

Step 3 — Confirm in Remote Manager

remote manager union

Check the Union in Explorer

Open the Union remote in the Explorer. Contents from all Upstreams appear as one merged folder.

Upstreams 1 — Google Drive example

union check folder google drive

Matches mygoogledrive:Meet Recordings.

Upstreams 2 — Dropbox example

union check folder dropbox

Matches drop:assets.
