Blimey. Have you been drinking?

I'm interested in which Windows APIs can't cope with / - as far as I knew,
/ has been OK in file paths since about DOS2. (But not on command lines,
obviously.)

But you're right, you have to be very careful where there's lots of string
comparison going on. My version here is running with a \ cache, but I did
get caught by a couple of things (the strchr in BuildCache, for example)

Probably true! I'll look at what would be involved.

I sympathise! I was just looking around for what was doing the ridiculous
copy that I could see going on filemon.

As well as software, it has a very large number of 3d cad models.

Funny enough, the repos is only about 3G. Of course, the WC is double the
size of the real data, because of the shadow copies in the .SVN folders.

So it's about 1G of data, really.

As for disk space, not a problem... Even this workstation has nearly 500G
in, though 320 of that is a RAID1 mirror, so is halved.

I tend to think that if I see a performance problem on this machine,
somebody else must be *really* hurting somewhere.

Cheers,

Will
