----------------------------------------------------------------- STACKER NOTE STACKER NOTE WINDOWS SWAP FILE SMALLER THAN CONFIGURED (Applies to Stacker 4.0) STAC FAX 4204 (03-28-1994) ----------------------------------------------------------------- BACKGROUND When you create or change a Windows Permanent Swap File (WPSF) using the Virtual Memory icon in the Control Panel, you may find that the size of the file is smaller than you expected. The problem lies with the requirement for the WPSF to exist on physically contiguous space on the hard disk. If there is any fragmentation on the drive at the location where Windows is placing the WPSF, the final resulting size of the file may be less than expected. You may correct this situation by removing the fragmentation. Note StacFax 4202 discusses the issues concerning Stacker and the WPSF in greater detail. SOLUTION - Defragment your physical hard disk. - Run the Stacker Optimizer. Defragment your physical hard disk Restart your computer with a DOS startup disk that has no reference to Stacker on it. Your Stacker drive will not be mounted, but your physical drive will be fully accessible. Note that if you have MS-DOS 6, procedures for making a Startup Disk are on page 178 of the MS-DOS User's Guide. 1. Determine which files on your drive are hidden. From the root directory of your C drive type: DIR /AH . This will display the hidden files. If your version of DOS does not support this command, you may need another manufacturer's utility to view the files. 2. Unhide all the files and subdirectories you find except MSDOS.SYS and IO.SYS. You may use the DOS ATTRIB command, Stacker's SATTRIB command, or a third party utility to unhide the files. If you are using MS-DOS 6, note that its ATTRIB command is on Setup disk # 1. To use Stacker's SATTRIB command you would put Stacker disk # 2 into the floppy drive, go to that drive and type: SATTRIB -S -H -R (PATH)(FILENAME) For example: SATTRIB -S -H -R C:\STACKER2.BIN Do this for each hidden file or directory. 3. Do not restart your computer. Some files may be re-hidden by the boot process. 4. Use a utility to defragment your disk. Programs such as Norton Utilities' Speedisk or PC Tools' Compress or MS-DOS's DEFRAG are examples of these utilities. 5. Since your Stacker drive is not mounted, you will not have access to your utilities on that drive. Use the "emergency" disks provided by the utility to run the defragmenter from the floppy drive. Note that if you are using MS-DOS 6, the DEFRAG utility is on Setup disk #1. See the manufacturer's instructions for details on running the defragmenter. 6. After the drive is defragmented, restart your computer. Run the Stacker Optimizer 1. Open the Stacker Toolbox by clicking on its icon in the Stacker Group in Windows. If you are in DOS, type the word STAC at the DOS prompt. 2. In Windows, click on the Optimize button on the toolbar. In DOS, select the Stacker Optimizer. 3. In either case, choose Full-MaxSpace. Follow the instructions on your screen. 4. After the Optimization is complete, go to the Virtual Memory icon in the Windows Control Panel. Set the WPSF to the size desired. The WPSF should now be sized correctly. ----------------------------------------------------------------- Copyright 1994 Stac Electronics
