Ram Disk Support
With the built in RamDisk Support Sandboxie-plus can automatically put selected sandboxes onti a dynamic Ram Disk created using the ImDisk Driver.
To make a sandbox operate form a ram drive volume add
UseRamDisk=y
to its sandboxie.ini section
To enable ram disk support you also need to add
RamDiskSizeKb=2097152
to the [GlobalSettings] section it denotes the maximal allowed disk size in Kilobytes, it is recommended to assign at least 1GB to the ram disk.
Please note that all sandboxes are sharing the same ram dis, and that the memory will be only allocated as needed and not all at once, hence you can assign up to half of your physical RAM without issues.
