cryo is an unusual file manager, especially the visual bookmarks and peer to peer file transfer features. This page describes the basics for common use cases.
The node view is graph based and lets you bookmark various items.
The nodes in the right view represent bookmarks to quickly jump between locations.
In the screenshot above all the green marked items can be dragged in to the view to create bookmarks. This works for:
- Folders from the file pane
- Hard drives
- Local and remote computers
- Shared folders on remote computers
- Breadcrumb path sections
To give a node a color select it and click on the color swatches at the bottom of the node view.
The quickest way to remove a bookmark is to select it and press Backspace.
Note: This will only remove the bookmark not the actual location e.g. the real folder won't be removed.
As alternative a bookmark can also be removed via its context menu.
In order to not clutter the node view with dozens of bookmarks, multiple node views can be created, each with its own set of bookmarks. For example one view per project. Views work very much like tabs.
The screenshot shows three views:
cryo homepage and
cryo on top. The currently active view is
cryo homepage and indicated by a blue dot.
To create a view right click on the empty space in the node view and select Add new node view from the context menu.
To remove a view open the context menu of it and select Delete... this will also pop-up a confirmation dialog to prevent deleting a view accidentally.
The dual-pane mode lets you quickly copy and move items between different locations and computers, either by drag and drop or keyboard shortcuts.
It supports tabs and common dual-pane shortcuts like F5, F6, F7 and F8 — see Keyboard shortcuts →
Toggle dual-pane / node view
Switching between these two modes can be done in multiple ways:
- Click on the top-right corner icons for dual-pane and node view
- ⌥+Down / Ctrl+Down keyboard shortcut
- Middle mouse click on a bookmark to opens the respective location in the right file pane
- Mouse gestures by far the fastest way — see Mouse gestures →

Node view and right file pane
- On a bookmark node enables dual-pane mode and opens the location in the right pane.
- On the node view empty space opens the right file pane with its last location.
- Anywhere in the right file pane toggles back to node view.
cryo supports free file sharing between computers over local network and Internet.
- Fast peer to peer transfers
- No cloud or middle server involved
- No registration or sign-up needed
- End to end encrypted
- No file size limits
The following section describes how file sharing in cryo works and gives an overview of the process. More background details can be found under Technology →
Connect computers via invitation
In order to share files between two computers they first need to be connected. This is done by using secure invitations. In the following example an invitation is created on a Windows 10 laptop named
MPI XPS-13 and accepted on a remote Linux computer named
1. Create an invitation
Menu > Remote > Create invitation...
2. Accept the invitation (remote computer)
Menu > Remote > Add by invitation...
The computers can be in the same local network or in remote locations, in which case both computers need to be connected to the Internet.
Right after accepting an invitation the remote computer is shown in the network list, but not yet connected.
4. Computers are connected
As soon as the connection is established, the remote computer will be shown as active.
Depending on the network conditions connecting might take 1–2 minutes given that both computers are online. If either of the computers isn't online, the process will be resumed automatically as soon as both are online.
