Depending on the size of your files, your available scratch disk space is nothing to write home about—or feel unduly confident about either: Scratch volume(s): F:\, 135,2G, 43,5G free E:\, 97,7G, 59,3G free C:\, 232,8G, 167,8G free You have precious little free space on your F and E drives, and on the C drive Photoshop's scratch disk has to slug it out with the swap files of the OS, your web browser's cache, and things like that. Just for reference, my primary scratch disk is a dedicated, physically separate, 200 GB internal hard drive. Many other users have a lot more. Roughly, in terms of available, contiguous scratch space, figure on at least 35 to 50 times the size of your largest file or more, multiplied by how many files you keep open. As for fixing permissions, I'm not a Windows specialist so I can't tell you how, but in essence it boils down to making sure you have full read and write permission on the drives and partitions you want to use as scratch.
