Scratching around for disk space
Question : I keep getting a message saying my "scratch
disk" is full when I try to save a photo I've been working on, and I'm
unable to save the file. How can I fix this?
Answer : Adobe's Photoshop program and its offshoots
temporarily grab extra hard drive space while you're editing and enhancing
images. This extra space - which gives the software its own little
workspace for processing and short-term data storage - is called the
scratch disk.
One common reason for the error message is that all the computer's memory
is in use, and its hard drive lacks the room the photo program needs. A
scratch disk may be three to five times the size of the file you're
working on, depending on the file and what you're doing to it.
Defragmenting your hard drive and deleting old files and documents to free
disk space might help. You should also check the image size settings for
the files you are working on.
Photoshop measures resolution in pixels per inch as opposed to the
dots-per-inch standard printers use; increasing the photo's resolution to
match the printer's resolution can result in huge space-eating files.
(Resolutions of 200 x 300pixels per inch are usually fine for printers.)
If your computer has several drives or partitions, you can pick a place
other than the main drive for Photoshop to use for its scratch disk.
To do so, go to the program's preferences area, and in the Plug-Ins &
Scratch Disks section, select the drive or partition to use. increasing
the memory the program is allowed to use might also help; these settings
are in the Memory & Image Cache area of the program's preferences.
