Basic Folder Preferences
This page allows you to set the locations for two important folders used by GIMP for temporary files. The pages below it allow you to customize the locations searched for resources such as brushes etc.; see Data Folders for a description that applies to them. You can change the folders here by editing the entries, or by pressing the buttons on the right to bring up a file chooser window.
Folders
This folder is used for temporary files: files created for
temporary storage of working data, and then deleted within
the same GIMP session. It does not require a lot of space
or high performance. By default, a subdirectory called
tmp
in your personal GIMP directory is
used, but if that disk is very cramped for space, or has
serious performance issues, you can change it to a different
directory. The directory must exist and be writable by
you, or bad things will happen.
This is the folder used as a "memory bank" when the total size of images and data open in GIMP exceeds the available RAM. If you work with very large images, or images with many layers, or have many images open at once, GIMP can potentially require hundreds of megabytes of swap space, so available disk space and performance are definitely things to think about for this folder. By default, it is set to your personal GIMP directory, but if you have another disk with more free space, or substantially better performance, you may see a significant benefit from moving your swap folder there. The directory must exist and be writable by you.
