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).
