EXD File - opening and understanding

Did your computer fail to open an EXD file? We explain what they are used for and recommend software that we know can open or otherwise handle your .EXD files.

What is an EXD file?

Files that contain the .exd file extension are cache files that are used by various Microsoft Office documents. These EXD files store cached information pertaining to ActiveX controls that have been inserted into the Office documents.

Controls are computer objects that are stored within the Control Toolbox of an associated Microsoft Office product. Check boxes, option buttons and text boxes are examples of controls that an application might use.

Each time an ActiveX control is inserted into an Office document, an EXD file is created. This allows for quicker insertion of additional controls.

EXD files are temporary files that are automatically removed by the application when the file is no longer needed.
