Thanks to all who responded to my earlier question regarding System 7.0 and Virtual 2.0. Now can virtual memory utilities such as these coexist with automatic disk optimizers such as DiskExpress II? I understand that Virtual needs its disk space to be contiguous, so an optimizer is necessary at some point, but can they both run at the same time? Thanks, Mike. -- Michael A.

I assume that you mean: can DiskExpress II work in automatic mode with Virtual? My approach was to make a separate volume (Swap) for Virtual's use. Then set Virtual to not automatically optimize that volume. However, I have yet to have DE II work in automatic mode without crashing the system. It may be incompatible with ParcPlace's Smalltalk-80, which is what I do most of my work in. I'm running Mac OS 6.0.5 with 8 meg and a LaCie 105 with SilverLining 5.23. I use DE II in manual mode every once in a while and am satisfied with that. Ken Warner

Using Disk Express II and Virtual would be bad if you optimized the swapfile while using virtual. You could however, partition your hard drive and have one partition for your swapfile only (this may slightly reduce your swapping speed though). From personal experience-I tried using DiskExpress II and Virtual (with the swap file on another partition) and may computer froze. No damage was done, but it was obvious that there were going to be some problems although I haven't called either software company to discuss the problem. -Mike Darweesh weesh@unclejack.crd.ge.com

This seems to be happen automagically. Examining DE II's Volume Info shows the swap file (the only file on my disk that's 13 Meg :-) as "Anchored." I presume that DE II leaves such files alone. >Personally, I think DiskExpress is a well written & designed utility, >but I think it's a bit compulsive to have to have yur HD optimized >everyday.

To make DE II stop optimizing while you're working, activate DE II, hit the Status button (the only one that shows, I believe), and hit Cancel. Note that the "Optimize Automatically" box is still checked. DE II will then perform the optimiziation later. If you leave your machine on all the time (I do) it will be fully optimized every morning (or whenever you get back to your Mac). Flip side, joe piazza --- In capitalism, man exploits man.
