I already wrote a very simple version of this function. As for every other
script I ever wrote - it's not finished and pretty straight forward.
Of course, it doesn't answer your question. Still, it relates, so here it
is.
By the way, it's designed to be added as a onScriptClose function.
def remAutosave():
script = nuke.Root()['name'].getValue()
autoS = script + '.autosave'
if os.path.isfile(autoS):
ask = nuke.ask('Autosave file found.\nDelete?')
if ask == True:
os.remove(autoS)
