Photoshop file permissions

After a recent upgrade to Windows XP at work, I ran in to a problem opening photoshop, where I would get the very helpful error message:

Could not initialize Photoshop because the file is locked. User ‘Properties’ command in the Windows explorer to unlock the file

It turned out that I didn’t have access permissions on the root folder of my second hard drive. Naturally, I’d set Photoshop to use the d:\ drive as its primary scratch disk to increase speed. Thankfully, I was able to change the permissions…whether they’ll be reset by group policy is another thing, however.

It’s a bit daft that Photoshop doesn’t let you specify a folder for the scratch files – that would get around this problem straight away, and that of Limited Users on XP, who aren’t allowed to create files in the root directory either.
