To store the results of your investigations, dotMemory uses so-called workspaces. A workspace, as the name suggests, saves everything you see on the screen: all open analyses including collected snapshots and analyses paths. In other words, it saves the current state of dotMemory.
The Difference Between Saving and Exporting a Snapshot
Saving a snapshot implies that the snapshot will be stored in a predefined directory (C:\Users\[username]\AppData\Local\JetBrains\dotMemory\[version]\Workspaces by default) in an unpacked format. This is convenient when you work with the snapshot locally.
If you want to move a workspace to another computer, you should use the export functionality. In this case, the snapshot will be saved as a single archive to any specified directory.
