post build conditions

[ace_of_john]

Hi ive just started using build events so im not very good at it yet, ive managed to rename an assembly once compiled like this

rename $(TargetFileName) $(TargetName).customextention

which changes the extention from .exe/.dll to .customextention

however once compiled and renamed, when i compile my solution without making changes to that project i get an error saying it cant rename a file that isnt there. so my question is how do i do something like this which doesnt work

if Exists $(TargetFileName) rename $(TargetFileName) $(TargetName).customextention

[ace_of_john]

My error is because $(TargetName).customext already exists so what i actualy need to do is

if exists $(TargetName).customext delete $(TargetName).customext

so to ammend my question how do i do that?

What about:

move /y $(TargetFileName) $(TargetName).customextention
