Getting started

The main window lists mounted volumes with their drive letter, size, usage and compression state, and shows overall memory use along the bottom.

The RAM File System main window
Main window example: two mounted volumes with size, usage and compression

To create a volume, use the Add button on the toolbar or Volume → Add in the main menu. Set at least the size and drive letter; the full option set is described in Adding a volume. The volume mounts immediately and appears as a local drive.

RAM FS volumes appear in This PC like any other physical drives

RAM FS volumes behave like any other drive, but its contents are cleared on dismount or shutdown unless saved to an image. A typical first task is to redirect temporary files to a RAM FS volume.

The screenshots in this manual are from the Windows edition; the macOS application looks and works the same, except that ordinary volumes are named rather than lettered and mount under /Volumes — see Cross-platform considerations.
