TmpDisk is a macOS utility that creates and manages virtual disks using system RAM instead of physical storage. These RAM disks provide fast temporary storage for files, downloads, archives, and editing workflows. Users can create disks with custom names, capacities, and file systems through a menu bar interface. The application supports opening mounted volumes in Finder and ejecting them when they are no longer needed. Its folder synchronization feature copies existing files into RAM disks and saves modifications back to their original locations. Scheduled synchronization and save-on-eject options help preserve important changes. A standalone command-line interface supports disk management without running the graphical application. RAM disk contents are otherwise permanently lost when disks are ejected or the computer shuts down.
