I have created my database in my windows phone app. Now i want to see whether it is created and stored data as i programmed it. But i am failed to view this database. Where my local database file get saved ? I like to mentioned that i have stored the database in the isolated storage. I heard about a method by using firefox extension i may be able to see the database but not sure what extension that is.
I've never heard about any Firefox extensions for browsing Isolated Storage on Windows Phone.
You can use Windows Phone Power Tools to copy your data file from the emulator or device to your desktop. If you're using Linq to Sql, you can open it in SQL Server Management Studio. Other data formats (i.e., Sqlite) can be opened in respective administration tools.
After Downloading Windows Phone power tools as mentioned by Michael, you can easily extract the database.
You may find difficulty in finding the exact file as the apps are listed by GUID and not their names in wp power tools.So you may have to go through each app to see which one contains the desired file.
Once you have located the file you will need a viewer (like this) to open the file.
This method worked for me just right.

Hi How do I delete a local file in my application after copying it to the IsolatedStorage?
I want to delete only the file in local folder. Not in the Isolated Storage. I'm using WP 7.1.

You don't have write access to the folder where your application is installed. It's therefore impossible to delete the file.
Windows Phone is designed to be one of the most secure environments in the mobile market. If you look at many of the standards it enforces you will see that this is a consistent theme.
For example:
Your app does not have the ability to intercept calls or text
messages (though the library exists)
Your app cannot modify hardware buttons (there is a few MINOR
exceptions to this rule like manipulating the back button event)
Your app cannot access memory locations outside of the Isolated
Storage it is assigned by the phone.
These standards are put in place to protect the user from malicious software and to keep a clean and consistent feel across the environment.
Protecting user files with File History talks about File History, which is basically a continuous backup for Windows 8. The blog discusses File History in depth, and also discusses how to integrate SkyDrive.
I want to programmatically disable backup of certain files. The files live on another server, and there's no need to back them up locally or put them on someone else's cloud. The blog and related articles doe not talk about opt'ing out of the service for application data.
How does one programmatically: (1) disable local file backups; and (2) disable cloud based backups. I'm interested in settings for both Windows 8 (desktop or laptop) and Windows Phone 8.
Related: Both Android and Apple have similar. For Android, we add android:allowBackup and set it to false in AndroidManifest.xml. For Apple, we can use kCFURLIsExcludedFromBackupKey file property or com.apple.MobileBackup extended attribute.

In Windows Phone 8, backup and restore settings are controlled by the user through system settings. An app cannot prevent itself from being backed up. However, note that the backup does not store any data associated with third party apps but rather only stores a list of installed apps
So basically you don't need to do anything in your app to prevent local files from being stored on SkyDrive if the user has enabled backup.
In Windows 8 everything can be backed up since an admin user will have full access to his computer files, I don't think you can restrict this. If you have sensitive data you can use DataProtectionProvider to protect it.
I am new to windows phone development. I am working on an app in which local db is required. But I am unable to create it or am not able to understand from where to start. I have tried many example but all in vein. I got some example running which ,in the emulator, I can add data but if I start the emulator again then all the data is vanished and doesn’t show any data. I am not getting why. Is there any way that I can extract the db from emulator and if yes then where is it reside and how can I open it after extracting it. Is sqlite database is supported by windows phone if yes then is it the best option to use it. For information I am using windows 8 and visual studio 2012. Please help me. Thanx in advance.

I am able to write to a .txt file in Windows Phone 7. I know I can read this file programmatically, but how will I be able to get this file to a PC? Where exactly is the file stored on the phone?
The SDK comes with the Isolated Storage Explorer tool which allows you to read and write files from Isolated Storage. Learn about it's usage at http://msdn.microsoft.com/en-us/library/hh286408(v=vs.92).aspx
This assumes that you're wanting to do this with files you're creating for dev/testing purposes.
If you want to make an application which allows you to create files which users can access from teh PC you're out of luck. Instead you'd need to look at emailing the info from the file or distributing the file via the web.
I'm building a windows phone 7 application using silverlight 4. I store my data in Isolated storage as outlined here. The program runs with no errors. My question is where I can see the file I have saved? Is it possible to find the file in the windows phone 7 emulator?
The "Mango" SDK ships with the ISETool that can take and restore snapshots of an application's isolated storage to/from a local directory:
# Copy data from IS to directory
ISETool.exe ts xd <PRODUCT-ID> "C:\TempDirectory\IsolatedStore"
# Copy data from IS to directory
ISETool.exe rs xd <PRODUCT-ID> "C:\TempDirectory\IsolatedStore"
After some more googling, i found this post. It seems that "the emulator does not save its state when you close it."
Also:
Saving State. To test compatibility with other .Net framework environments I just re-implemented some standard Isolated Storage example code for application settings in my Silverlight application. It just works. But note, the preview emulator doesn’t hold state beyond debug sessions – so you can only test state storage in your application session at the moment.
from this post. (http://wotudo.net/blogs/wotudo/archive/2010/03/15/mix-building-a-windows-phone-7-series-silverlight-application.aspx)
The intent of isolated storage is for it to be only accessible by the application that wrote the data in that store. Isolated storage can not be shared across applications, hence being able to find the files you store in isolated storage through an explorer like experience isn't allowed.
If you need to access the files to observe the data in it, or to share it across applications, consider storing the file in a cloud service. Or if you need to look at the contents of that file for debug purposes, maybe add an option to write that file on your server.
I use this program to help me capture the data from the windows 7 phone emulator.
