I need to copy a .sdf SQL Server CE database file from my WP 8 device to my computer. How can I do that?
Using the WP8 Emulator and Isolated Explorer i can copy from my emulator but I need to copy from my real device.
Regards
JR
You can write the database file to the SD Card.
MSDN : SD Card Example : Make sure you have removableStorage capability in app manifest.
You also might need to associate your app to handle the file extension you want to copy to the SD Card.
MSDN : File associations
Let me know how it goes or if you need more help.

I'm recently looking into the file-sharing features of Windows Phone 8.1. One possibility is, to do this via file extensions. My question is, how exactly my app gets access to a launched file that it registered to handle.
I know that in WP8 this was done with a URI and a file token (https://msdn.microsoft.com/en-us/library/windows/apps/jj206987%28v=vs.105%29.aspx), but since the SharedStorageAccessManager class is not available anymore, I guess that it must be done different in 8.1.
So: What happens on "OS-level" in Win8.1/WP8.1 when an app is launched via a file extension, and how does the target-app actually get the launched file?
Thanks in Advance!
The app can register as a file handler in its Package.appxmanifest. Openthe manifest designer in Visual Studio, go to the Declarations tab, and add a File Type Associations declaration. You'll be prompted to fill out the details.
The app's Application.OnFileActivated method will be called with the launched StorageFiles in the FileActivatedEventArgs.Files property.
See How to handle file activation and the Association Launching sample for documentation and walkthroughs.
At a system level this all gets stored in the registry and when the launcher is called on a file the shell looks up the association then uses COM (or historically command line parameters or DDE) to launch or connect to the app registered for the file type. The details are hidden from Windows Runtime apps but are more directly exposed to desktop apps on Windows. See File type and URI associations model Implementing a Custom File Format
In a Windows Phone 8.0 application I calculate the size of a file with this following method:
Windows.Storage.FileProperties.BasicProperties props = await thisFile.GetBasicPropertiesAsync();
size = props.Size;
I've read here that this is for Windows Stors apps or WP 8.1 only, not below but it works and I am not getting any Exceptions. Why does it work if it's not supported? Are they going to reject my application submitting to Store?
If it's really not supported, what is the proper way, API to calculate the size of a file in Isolated Storage on WP 8.0?
If it works, it might be the documentation problem and there is no reason to reject your application from the store.
In my application after first login/registration I need to download data from server this will take some time. And user can quit the application while data is loading. So I need to download the data in background process. I know I can use backgorund application/Class and register this class in windows phone application but this is only for one time. Is there any other way to do so without creating backgourd task for this?
Maybe this will help,

I am working a wp8 app which can read some different types file.Then launch them in a simply way.Like we can launch mp3 using MediaPlayerLauncher .But I failed.Any help will be kind to me.Thanks
I assume that you managed to use ExternalStorage. Firt of all you are not able to see this (mp3) files because they are reserved. What you can do is to change extensions to them and copy to InternalStorage. As you have done that you can play them well with MediaElement or BackGroundAudio.
Also it's not possible (for now) to play directly from ExternalStorage (SD card).
