I want to get a file which i saved in a specific directory on my phone. How can I find and get a ref to it so I can do with it something different like uploading to a server?

Thanks in advance.

File f = new File("location");

Remember, if you're trying to access the sd card you need to set permissions. Then just handle the "file" in whatever way it is you're trying to do something.

If you're looking to use the SDCard check this post: Permission to write to the SD card

[Edit - Example]

String filenameToWrite = "Test.jpg"
try{
    File f = new File(Environment.getExternalStorageDirectory() + "/Photos/");
    if (f.exists()){
        File fileToWrite = new File(Environment.getExternalStorageDirectory() + "/Photos/" + filenameToWrite;
        // Do something to write file, save bitmap, save byte stream, etc.
    }
} catch(IOException e){
    Log.e("File", "Could not save file, error occured: " + e.toString());
}

Here's a few getting started tutorials to help you understand how to read and write files in java. This (apart from the 'path') is a java question, not an Android one.

Well where do you store your file?

Store the file in a specific area such as 

Environment.getExternalStorageDirectory()

Then when you want to read it, just use the file name used and the path obtained from the above method.
