ADOBE PHOTOSHOP ELEMENTS
User Guide
To suppress the loading of a plug-in or folder of 
plug-ins:
Add a tilde character (~) at the beginning of the 
plug-in name, folder, or directory. That file (or 
all files in the folder) will be ignored by the appli-
cation once it has been restarted.
To view information about installed plug-ins:
Choose Help > About Plug-In and select a plug-in 
from the submenu (Windows) or choose Apple 
menu > About Plug-In and select a plug-in from 
the submenu (Mac OS).
Assigning scratch disks
When your system does not have enough RAM to 
perform an operation, Photoshop Elements uses a 
proprietary virtual memory technology, also called 
scratch disks. A scratch disk is any drive or a 
partition of a drive with free memory. By default, 
Photoshop Elements uses the hard drive that the 
operating system is installed on as its primary 
scratch disk. 
You can change the primary scratch disk or 
designate a second, third, or fourth scratch disk, to 
be used when the primary disk is full. Your 
primary scratch disk should be your fastest hard 
disk, and should have plenty of defragmented 
space available. 
The following guidelines can help you assign 
scratch disks:
You can use up to four scratch disks of any size 
your file system supports. Photoshop lets you 
create up to 200 GB of scratch disk space using 
those scratch disks.
For best performance, scratch disks should be on 
a different drive than any large files you are editing.
Scratch disks should be on a different drive than 
the one used for virtual memory.
Scratch disks should be on a local drive. That is, 
they should not be accessed over a network.
Scratch disks should be conventional (non-
removable) media.
Raid disks/disk arrays are good choices for 
dedicated scratch disk volumes.
Drives with scratch disks should be defrag-
mented regularly.
To change the scratch disk assignment:
1
Choose Edit > Preferences > Plug-Ins & Scratch 
Disks.
2
Select the desired disks from the menu (you can 
assign up to four scratch disks).
3
Click OK.
4
Restart Photoshop Elements for the change to 
take effect.
Important: The scratch disk file that is created by 
Photoshop Elements must be in contiguous hard disk 
space. For this reason you should frequently optimize 
your hard disk. Adobe recommends that you use a 
disk tool utility, such as Windows Disk Defragmenter 
or Norton Speed Disk, to defragment your hard drive 
on a regular basis. See your Windows or Mac OS 
documentation for information on defragmentation 
utilities.
