Comment 3 for bug 953293

According to comments in original editors.conf you should list file extensions and according to the instructions in http://doc.bazaar.canonical.com/explorer/en/tutorials/customization.html you mustn't use any placeholders in the editors.conf, only filename/path of the editor

# Editor applications for various file extensions on various desktops.
# A DEFAULT section can be given providing cross-platform defaults.
# The recognised desktop names are gnome, kde, windows and osx.
# Within each section, the key is a comma separated list of file
# extensions and the value is the name of the application to edit
# the file with. For example:
#
# [DEFAULT]
# doc, xls, ppt = ooffice
#
# [windows]
# vsd, vss, vst, vdx, vsx, vtx = visio

So, in your case the settings should be

uxf = "C:\Users\Ray.Hendrey\bin\test_cmd_parms.bat"

And Explorer will run "editor" for "uxf" as

"C:\Users\Ray.Hendrey\bin\test_cmd_parms.bat" /path/to/selected/file
