1The screen — two pairs of tree and files
The screen has two pairs: Q·O and R·O. The left side (Q·R) is a folder tree, and the right side (O) is the file list of the folder that tree points to. The two pairs are identical copies — pick on top and send down, or the other way around. The destination of a copy or move is always the folder the opposite tree points to.
Drag the handles between panels to resize them, and tap a letter button like Q R to widen that panel. On a phone you see one panel at a time, large.
2Connecting folders — the tree's +
- Local — pick a folder on this device. Your files stay where they are; the app only remembers the way in. It's normal for the browser to ask for permission once more when you come back (installing the app makes this rarer).
- Google Drive — sign in, then pick a folder in the picker. Drive folders you connect follow you to all your devices automatically.
- Remote — creates a QR code, link and 4-digit code that hand one of your folders to someone else (see 5 below).
- New folder — creates a folder inside the one you're looking at.
3Your devices — sign in and they see each other
Devices signed in with the same account show up in each other's tree automatically. Unnamed devices are called Local, Local 2, … in the order they joined; tap ✎ on a device row to give it a name you like (Phone, Mac, …), and it shows the same on all your devices. Your current device carries the This device tag.
- Green dot = online now → you can open that device's folders and take files from it.
- Red dot = offline → it stays in the list, but that device has to be on before you can open it.
- Files go from device to device directly (encrypted) — that's why the other device has to be on.
4Working with files
| To do this | How |
|---|---|
| Select | Tap a file (long-press for multi-select), or use Select · Select all |
| Copy · Move | Once you select, a card appears in the tree — the destination is the folder the opposite tree points to |
| Delete | Moves to the Trash and is kept for 7 days; undo from the banner or with ⌘Z |
| Rename | Select a single file, then Rename on the card |
| Search | The search at the top of the file panel — it looks into subfolders too |
| Sort | Name · Size · Date · Type — for very large folders, by name is fastest |
Moving many files puts them in a task queue that runs one at a time. If it gets interrupted, press Resume and only what didn't finish runs again. You can follow progress in the account (Tasks) panel at the top right.
5Sharing with others — QR code · link · 4-digit code
- + → Remote: the other person scans the QR code or opens the link and is connected right away. Codes are single-use and last 3 minutes — if one expires, just make a new one.
- They show up in your tree as Shared 1, Shared 2, …, and ✎ lets you give them a name of your own.
- By default they can only view, take and add — deleting is blocked, and if they try to delete, an approval prompt appears on your screen.
6Viewing — what opens
Photos (pinch zoom, HEIC included), videos (even huge ones play right away), PDF (remembers your page), EPUB, documents (Word · Excel · PowerPoint previews), text and archives (browse inside a ZIP) open right in the app. Turn on Preview to show thumbnails in the list.
7When it won't connect
- Tap ↻ at the top right to recheck online status and connections from scratch.
- If the dot is green but the folder won't open, wait a moment and tap ↻ — the devices retry the direct connection.
- Across different networks, like 5G ↔ Wi-Fi, the devices are linked through an encrypted relay (no one can see the contents). If it still fails, putting both devices on the same Wi-Fi is the surest fix.
- When a permission prompt appears, choose Allow — asking again on each visit is normal browser behavior.
8Safety — your files are not on a server
- Neither your files nor your folder lists are stored on a server. They travel device to device, encrypted.
- The only thing tied to your account is a small settings file in your own Google Drive (connected Drive folders, device names) — it's yours, and you can delete it any time.
- Sign-in is needed only for remote features. Managing local folders works without signing in.
