It happens sometimes when I rewrite a max patcher file, for example

"mydel.pat" becomes "mydel.pat62", then I have two similary rewrote files : "mydel.pat" & "myname.pat62" in the finder.

Not a problem, but how strange, isnt'it ?

Max has been doing this for about a decade. Google the Max list on "safe save".
