file_types:filetype_editor:replace_menu

The Replace Menu tab lets you add commands to the context menu displayed when you right-click on a file icon in the Confirm File Replace dialog (displayed when copying a file over one that already exists). Using this you can define commands that, for example, let you compare the old and new files using an external comparison tool.

For example, a command to compare the two files using Beyond Compare might look like this:

"C:\Program Files (x86)\Beyond Compare 4\BCompare.exe" {filepath$} {filepathdest$}

Then, in the Replace dialog, clicking either of the file thumbnails shows this command at the top of the context menu.
