Troubleshooting
Operations seem unusually slow, or out-of-memory
messages appear frequently.
Your system settings—such as the amount of RAM
and use of the system's virtual memory—may be
slowing down Adobe Photoshop operations. For
information on setting up RAM and virtual
memory in Photoshop and for other tips on
improving performance, see the section
"Improving Performance" in online Help.
Scratch disk full messages appear.
This error usually occurs when you are low on
hard drive space, which Photoshop needs to
process your images. Choose File > Preferences >
Plug-Ins & Scratch Disks to determine where your
scratch disks are located. Then use Windows
Explorer or the Mac OS Finder to determine the
amount of space available on those hard drives. Set
the primary scratch disk space to a drive which
contains contiguous free space that equals at least
3 to 5 times the size of your document in
Photoshop.
For more information on the scratch disk, see
Determining the amount of scratch disk space
required in the online Help.
Space on hard disk appears lost.
When a Photoshop file is open, the system creates
a temporary (.tmp) file to hold the information
about the open images. Normally, this temporary
file is deleted when you quit the program.
However, sometimes when the system crashes the
file is not deleted. Undeleted temporary files can
cause system, printing, scanning, and saving errors
and can take up space unnecessarily on the scratch
disk volume.
Note: Before attempting to delete temporary files,
quit Photoshop and any other applications currently
running. In the unlikely event that another appli-
cation uses the .tmp extension for anything other
than Windows temp files, these files should not be
deleted.
To restore the hard disk space and fix these
problems caused by temporary files in Windows,
search for files ending in .tmp on all hard drives
from the root directory, including subfolders.
Then delete the .tmp files and run the Scandisk
utility and a defragmentation utility as described
in "Before you call Adobe Technical Support" on
page 361. (Note that you will not be able to delete
the active Windows .tmp file.) For more infor-
mation, see your Windows documentation.
To restore the hard disk space and fix these
problems caused by temporary files on your
Macintosh, empty the Trash to delete the
temporary files. For more information, see your
Macintosh documentation.
