RAMFS by Karl Olson is a "remote file system" (as opposed to a "local file system").

Create as many RAM drives as you want, using the drive letters that you want
Size only limited by available RAM and swap disk space
Allocates swappable RAM from OS/2 as necessary when files are created, and releases it again when files are deleted
Long file name support like in HPFS. Case isn't significant, but preserved like in HPFS. Files with long names are not visible from DOS and WINOS2 programs.
Extended Attributes - up to 64 KB total for each file/directory (HPFS supports up to 64 KB for each EA, up to 256 KB total for each file/ directory)
RAM is allocated in units of one page (4 KB)

Syntax

IFS=RAMFS.IFS <parameters>

Parameter

/Q: Disables messages at boot

Use RAMDISK.EXE to create a RAM drive. To create a drive R:, type RAMDISK R:

Tip by Ulrich Möller: Some applications have trouble with TEMP being set to the root directory of a drive. So if you set TEMP to the RAM disk, have a \temp directory created thru the following statement in CONFIG.SYS:

IFS=drive:\common\ifs\RAMFS.IFS
CALL=drive:\common\ifs\RAMDISK.EXE R:
RUN=drive:\OS2\CMD.EXE /C md R:\temp

(replace R: with your system's paths, of course).
