I solved my problem with this batch Your .bat makes in essence what did my variant for random .ext, while yours have additonal disk writes and hence should be slower. I see no advantage of it and have no idea what you've found wrong with my solution. But I'm glad then even worse code satisfies. Was …

Eureka!!! Thank you all! I solved my problem with this batch: @echo off del c:\dosboxportable\target_file\*.* copy C:\DOSBoxPortable\dosbox.conf C:\DOSBoxPortable\Data\settings\ copy c:\dosboxportable\APP.exe c:\dosboxportable\target_file\ copy %~f1 c:\dosboxportable\target_file\%~n1%~x1 echo [ …

Does ¨copy %~f1 c:\app\somefile.ext¨ stands for ¨copy example.ext selected in its path in c:\app\ and rename it in somefile.ext? Yes. If so can I write ¨copy %~f1 c:\app\*.*¨ to copy in c:\app\ the same file This way it will copy .ext file to c:\app\, but will not rename it. So instead of only 1 …

...excuse me Terz... Does ¨copy %~f1 c:\app\somefile.ext¨ stands for ¨copy example.ext selected in its path in c:\app\ and rename it in somefile.ext? If so can I write ¨copy %~f1 c:\app\*.*¨ to copy in c:\app\ the same file or it`s better ¨copy %~f1 c:\app\%~f1¨

and if I want open an ¨*.ext file¨ with a variable extention? Files that I open have differt extention because I name them according to my needs and I need modify extentions to identify better what is ¨inside¨. You may use names for info, instead of extensions. For example name [info].ext, or name. …

Why mess with the Registry by creating needless new associations when there are so many better ways to do it without touching the Registry? You would still have to individually setup each game for its individual needs. ...sorry collector but I`m not tell about games. I need to open every time a …

@Terz ...be patient...and if I want open an ¨*.ext file¨ with a variable extention? Files that I open have differt extention because I name them according to my needs and I need modify extentions to identify better what is ¨inside¨. Thank you Samuele
