Handled File Extensions Dialog

This dialog is used to configure what file extensions you wish Dependency Walker to "handle". Dependency Walker will register itself with your operating system as a viewer for any file extensions you add within this dialog. Once registered, you can right-click on a handled file in any explorer window and choose "View Dependencies" from the context menu to launch Dependency Walker and process that file. Handled files are also shown by default in the File Open Dialog when it is first displayed.

You may also use the Handled File Extensions Dialog to remove handled file extensions. This will remove the "View Dependencies" menu item from the right-click explorer context menu for the extensions you wish to stop handling.

Usually, you will want Dependency Walker to handle all extensions that represent 32-bit or 64-bit Windows modules. Some common ones are EXE, DLL, and OCX. However, developers are free to use any extension they wish when creating modules. Because of this, Dependency Walker provides the option to scan one or more of your disk drives looking for files that are 32-bit or 64-bit Windows modules and automatically add them to your handled file extension list.


This field allows you to manually enter an extension and add it to the list. You do not need to enter a period as part of the extension. After you type in an extension, you need to press the Add button to add it to the list.


This button adds the extension in the Extension field to the extension list. If there is no text in the Extension field or the extension entered is already in the list, then this button will be disabled.

This button will display the Search for Executable File Extensions Dialog, which allows you to automatically search one or more of your disk drives for 32-bit and 64-bit Windows modules.
