External and internal storage how to check both - android

I get the difference between the two but is there a way to see the internal storage file? Because I want to check if the file is like I want it to be.
Then I created a external file and when I'm programming in eclipse and I test my app the file is created and I can see it on my phone via a filemanager but when I browse via my windows explorer to the HTC memory the file isn't there. Is this because I'm working in eclipse and this is debug? Or is there a way to check the file on my computer?
Thanks already

public static String filePath = Environment.getExternalStorageDirectory() + your folder path
it give a path of your memory storage either it is internal or external it give

Bhanu Sharma solution works. For the external file there is in eclipse a nice way.
Open the file explorer window in eclipse and then you can click a file and right above there are icons to push and pull the file to your device. ;-)

Path of a file in an internal directory

I have a file gpac.xlsx in the internal storage of my phone. I want to get its path. In android, it's confusing. Which one of these is the correct path?
/data/sdcard0/gpac.xlsx
/data/emulated/0/gpac.xlsx
Or some other besides these?
I have a file gpac.xlsx in the internal storage of my phone.
Based on your sample paths, your file is in what the Android SDK refers to as external storage.
I want to get its path.
new File(Environment.getExternalStorageDirectory(), "gpac.xlsx");
Which one of these is the correct path?
It could be either of those or something else. Use the Java snippet shown above to derive the proper path at runtime for the particular device that your code happens to be running on.

Where can I see the file in path getApplicationContext().getFilesDir()

I am using the below code to create a file in android as
File file = new File(getApplicationContext().getFilesDir(), "content.txt");
I want to open the file in my phone. I went to the path
Local storage/Android/data/<my package>/files/
However, I cannot see the file. My Android version is 5.0.1. What is happen? One more thing, Do you think the above way is a good way to save file? What is common path to save a file in Android? Thanks
The file locates in /data/data/[your package]/files,it's app private directory.
It's a good way or not depends on the purpose of your file.
if you want your file visable only to you(the app developer),the folder is right
if the file can be visable to others and the file is large,then you can put it to sdcard folder
if you want the file stay even if your app being removed,you shouldn't put it in this folder.Because when an app removed,the all data in /data/data/[package name]/ will be deleted also.
You find in:
/data/data/[your package name]/files/

How to pick file from /data/data/ path from a device

I have created a file in the below path using my applcation.
/data/data/VisionEPODErrorLog/ErrorLog.txt
I am able to see the file using Eclipse DDMS->File Explore ->Data
But when I installed my applcation in the mob device I am not getting that path in the device.
I need to see the exact file in the device
Is there any third party applcation needed to access the path.If so whats that or is there any way else to get that file from the device.if anyone konws please let me konw
please use below method
BufferedInputStream in = new BufferedInputStream(Mtx.getContext().openFileInput("ErrorLog.txt"));
i used in my application to read file stored under /data/data/ directory
i think this will help
/data/data/VisionEPODErrorLog/ErrorLog.txt
That is an exceptionally bad idea. Please do not do that. Please use getFilesDir() to get the root of your internal storage for files.
But when I installed my applcation in the mob device I am not getting that path in the device.
You should not be able to write there on a production device. Please do not invent random paths. Please use getFilesDir() to get the root of your internal storage for files.
You certainly cannot view anything in /data/data on a production device via any tool, unless you root your phone.

Android: How can i download a file from a URL to asset folder of the app?

When I start running the app in the mobile, it must connect to a URL and download dataset(files) to the app folder of the app..Is this possible? if so please could you show me a sample ?
you cannot download files in app's Asset folder. Instead you should use getCacheDir() (on internal memory) or getExternalCacheDir() (on SD card, available in Froyo and above) to download and retrieve your files.
All the details are available here:
http://developer.android.com/guide/topics/data/data-storage.html
File file = new File(getFilesDir(), "sample.jpg");
use this to get an internal app private directory. You can use debug feature to actually see what is the directory it is referring.

Read a file out of an android application

I need to place a file on a specific folder, so that my application can read it. First i want to try to create a new file with a specific path, but anyway i try, on the android dev tool on eclipse, I have an IOException.
Do you know a way to create "helloworld.txt" - For example - on the virtual device?
Thanks.
PS: I tried "new File(Environment.get..., "helloworld.txt").mkdirs();", and stuffs like that
If you want to create a file in the sdcard, you should check if the sdcard is ready (more info here), apart from the fact you need this permission in the AndroidManifest.xml
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
Try not use hard-code the path of the sdcard, use instead the API for that.
On the other hand, if you want to create a private file on the phone storage you can use this methods:
FileOutputStream fos = context.openFileOutput(FILE_NAME, Context.MODE_PRIVATE);
You can not access system folder by using android app.You need to transfer the file from your system to Android Emulator's Virtual SD Card by using file explorer availble with ADT plugin for android in eclipse.
Open file explorer in eclipse and import the file to device.
