To build this small application, you will have needed to have added Pelle's tools to the BIN directory of MASM64. The exe builds at 8k with an icon, manifest and version control block so its probably in the class of minimum application size. It does not have confirmation or search and replace, that can be done later with a bit more code up. A note on an include MACRO. The spill space for the remote richedit procedure jumped up and bit me so I ended up writing a MACRO to adjust spill space.
stk@@local equ <LOCAL>
.stackspace MACRO count
LOCAL padding
stk@@local padding[count]:QWORD
