Use Notepad (Windows) or a text editor on macOS to create a plain text file (.txt).
Optional extensions are used to manage specialized behaviors, such as disabling click to commit, VM buffering management, and disabling scratch disk compression.

# Disable Scratch Compression |
|
By default, Photoshop compresses pages before writing them to the scratch file. This compression does not result in a smaller scratch file since Photoshop must still reserve space for the uncompressed pages. For slow disk drives or SCSI implementations, however, the reduction in the data to be transferred to or from disk more than compensates for the time needed to compress or decompress the data. For fast disk drives and SCSI implementations, this is not the case. Disable Scratch Compression provides a slight performance improvement on machines with fast disk drives and SCSI implementations.
Disable VM Buffering
Required Text |
Compatibility |
# Disable VM Buffering |
|
When running on a macOS with more than 4 GB of RAM, Photoshop tells the OS to use the extra RAM as a buffer for the scratch file to speed up scratch file access. Disabling VM Buffering ensures that Photoshop doesn't access the extra RAM.

# Force VM Buffering |
|
When running on a macOS with less than 4 GB of RAM, Photoshop does not tell the OS to use the extra RAM as a buffer for the scratch file to speed up scratch file access. Force VM Buffering forces Photoshop to access RAM for VM buffering.
Overscroll Always
In current versions of Photoshop, a preference controls the overscroll behavior:
- Select Preferences > Tools and enable Overscroll.
Remember Slow Files
Required Text |
Compatibility |
# Remember Slow Files |
|
By default, Photoshop removes files from its recent file list if it ever takes longer than 20 ticks (1/3 second) to figure out where the file is when the list is updated after you open or save a file. Some removable devices and some network drives may take longer than this. Remember Slow Files prevents the recent file list from forgetting about files that take too long to resolve when the list is updated (it allows up to 20 seconds). However, saving or opening a file may take longer if this plug-in is installed.
Turn on Legacy Healing Brush
In the current version of Photoshop, you can revert to the legacy behavior for the Healing Brush tool by enabling Use Legacy in the tool options bar.
A new Diffusion slider allows you to achieve results similar to the legacy algorithm. See Healing brush examples for more information.
Use WinTab instead of Windows Ink
Required Text |
Compatibility |
# Use WinTab |
|
On Windows 10, Photoshop uses Windows Ink to control the interaction of Photoshop and a stylus device. Using Windows Ink gives you better stroke results and allows you to use your tablet PC or convertible device without having to install a driver.
If the tablet uses a WinTab driver and does not have an option to use Windows Ink, you can force Photoshop to use WinTab instead of Windows Ink.
See Tablet support for Photoshop for more information.
Unlimited Preview Size
Required Text |
Compatibility |
# Unlimited Preview Size |
|
If you have the Full Size option for Image Previews turned on in the Saving Files preferences, Photoshop limits the size of the preview to 512 x 512 pixels. Unlimited Preview Size removes the 512 x 512–pixel limit on file previews.
Disable Transform Proportionally by Default
In the current version of Photoshop, you can revert to the legacy behavior for transform by enabling Preferences > General > Use Legacy Free Transform.
See Consistent transform behavior for more details

# Disable automatically setting default font size |
|
Photoshop calculates the default font size based on document resolution and zoom factor. When a new document is created, or an existing document without type layers selected is opened, the font size will be reset to the newly calculated default font size. Also, the leading will be set to Auto.
Previously, the default font size was always 12 pt, and sometimes this would be too small depending on resolution and zoom factor. Disabling this option will return legacy/default functionality.
