Why can I do to open files, if it says cannot find the right application to perform this action

[abd76]

I would just like to know an app. That will open all documents, files,and so forth.

what is the file extension that you want to open and says "cannot find the right application to perform this action
" ?

There is no such app that can open all file types for you.
Most file formats are proprietary to the software makers and require special apps to read them.

What is the file type that you are trying to open?
