Kotlin Extension Properties  No file will be create when you make a File object  it is only an interface   To make working with files easier  there is an existing  toFile function on Uri  You can also add an extension property on File and or Uri  to simplify usage further   val File  exists get     this  exists      false val Uri  exists get     File this toString  exists     Then just use uri exists or file exists to check

When you say  in you package folder   do you mean your local app files  If so you can get a list of them using the Context fileList   method  Just iterate through and look for your file  That s assuming you saved the original file with Context openFileOutput     Sample code  in an Activity    public void onCreate            super onCreate           String   files   fileList        for  String file   files            if  file equals myFileName                   file exits

When you use this code  you are not creating a new File  it s just creating an object reference for that file and testing if it exists or not   File file   new File filePath   if file exists           do something
