i cannot find my written files

Question

I wrote a file to the sd card (external storage) of my phone. I cannot see these files in the created folder for these files, but i can use them in the app. Here is proof i write to my sd card:

if (!isExternalStorageAvailable() || isExternalStorageReadOnly()) {
        b3.setEnabled(false);
    } else {
        myExternalFile = new File(getExternalFilesDir(filepath), file_namea);
    }

then i later on declare the file:

 FileOutputStream fos = new FileOutputStream(myExternalFile);
 ObjectOutputStream of = new ObjectOutputStream(fos);

This works as the folder i created and i can use the file in the app but why can i not see or touch it when looking on my sd card?I would like to be able to email/ move the text files to my main pc but i cannot. Any ideas of how i can do so?

private String filepath = "MyFileStorage";
File myExternalFile;
String myData = "";

Can you log the actual value of `getExternalFilesDir(filepath)`. On some devices the internal storage is available as simulated external storage, so your files might have ended up in the internal memory. — Lothar, Sep 01 '17 at 12:03
"why can i not see or touch it when looking on my sd card?" - please clarify what you mean by "looking on my sd card". — DodgyCodeException, Sep 01 '17 at 12:20
@DodgyCodeException when i go through the phones folders outside of the app — Joshua Villalta, Sep 01 '17 at 12:36
Please tell the value of myExternalFile.getAbsolutePath(). All has nothing to do with a removable microSD card. So you do not have to look on it. This is what @Lothar asked. — greenapps, Sep 01 '17 at 12:39
`when i go through the phones folders outside of the app` Still unclear what you are doing. How? — greenapps, Sep 01 '17 at 12:41
`private String filepath = "MyFileStorage";` That is not a file path. So don't name that variable like that. Confusing code! — greenapps, Sep 01 '17 at 12:42
@greenapps when i connect my phone and go through the computer section with shows me the internal storage and my sd card — Joshua Villalta, Sep 01 '17 at 12:48
@greenapps myExternalFile.getAbsolutePath(). how can i tag this in logcat? — Joshua Villalta, Sep 01 '17 at 12:48
@greenapps i want to impliment this into my code https://stackoverflow.com/questions/32789157/how-to-write-files-to-external-public-storage-in-android-so-that-they-are-visibl — Joshua Villalta, Sep 01 '17 at 12:49
As you do not have to look at the sd card you should look elsewhere. Now tell us value of getAbsolutePath(). — greenapps, Sep 01 '17 at 12:57
But of course you should use a File Explorer app on your device. Even if you look at the right path from your computer you will not see the file at once. — greenapps, Sep 01 '17 at 13:00
Why? What should we see? Can you read that mess? Remove it. Post only relevant lines. And put them in a code block so they are readable. — greenapps, Sep 01 '17 at 13:01
If you cannot find that Log.d() statement in your logs than you could show a Toast() too of course. — greenapps, Sep 01 '17 at 13:03
