Optional extensions are used to manage specialized behaviors such as overscrolling, VM buffering management, and disabling scratch disk compression.
Example: Type the following text:
# Force VM Buffering
into the text file. Put each setting's required text on a new line in the text file.

Save the file as "PSUserConfig.txt" to your Photoshop version settings folder:
- [Installation Drive]:\Users\[User Name]\AppData\Roaming\Adobe\[Photoshop_version]\[Photoshop_version]Settings\
- //Users/[User Name]/Library/Preferences/[Photoshop_version]Settings/
The user Library folder is hidden on macOS. See Access hidden user library files | macOS for more information.
When enabled, clicking on the canvas with an active Type layer will commit the text without having to hit Enter or Esc or click on the commit checkbox in the options bar. Also attempting to move a Background layer will prompt with an option to Convert to Normal Layer. Disabling this option will return legacy/default functionality.
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.
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.
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.
In current versions of Photoshop, a preference controls the overscroll behavior:
- Select Preferences > Tools and enable Overscroll.
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.
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.
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.
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.
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
By default, Photoshop captures the document type of the document being saved from the app for the Adobe Product Improvement Program.
