What Is a GRD File?
A file with the GRDfile extensionmight be an Adobe Photoshop gradient file.
These files are used to store presets which define how multiple colors should blend together.
Use one to apply the same blending effect to multiple objects or backgrounds.
Others might be used as encrypted disk image files in PhysTechSoft’s StrongDisk software.
How to Open a GRD File
GRD files can be opened withAdobe PhotoshopandAdobe Photoshop Elements.
This is usually in a folder like this:
Use theExportorSavebutton to make your own GRD file.
The free online image editorPhotopeais very similar to Photoshop and can also import a GRD file.
There’s another menu in that window that lets you chooseLoad .GRD.
Surfer grid files can be opened using Golden Software’sSurfer,Grapher,Didger, andVoxlertools.
If those programs aren’t working, tryGDALorDIVA-GIS.
The only way to open it would be with theStrongDisk Prosoftware from PhysTechSoft, via itsMount>Browsebutton.
Other formats may also exist that use this extension.

To choose which one the file defaults to,change the file associations in Windows.
