----------------------------------

Interesting, if I take the anchor out a different one is added each time.  =
Might be user specific.  I edited to take the anchor out of the link.

> We are writing an application using Ionic 2 for Windows 10. The applicati=
on will need to share data between different users on the same machine ther=
efore we are using the shared local folder to save the data to as described=
 in the =E2=80=9CUsing Shared Local=E2=80=9D section of this page: https://=
blogs.windows.com/buildingapps/2016/05/24/sharing-your-local-app-data
> This method works great and we made changes to the Cordova-Sqlite-Storage=
 plugin so it will write the database file to the shared local folder. The =
problem is when we update our application the shared local folder is remove=
d thereby erasing all of the saved data.
> I created a native C# application to see if we had the same behavior when=
 we updated a native application. When we updated the native app the shared=
 local folder was not removed therefore this is an issue specific to our hy=
brid application.
> My first thought was maybe the Add-AppDevPackage.ps1 scripts were differe=
nt between the native and Ionic 2 application since that is the script that=
 we used to perform the installation and update. I ran a comparison tool to=
 compare the scripts from the Ionic2 and native applications however the tw=
o files are exactly the same.
> I can also verify that the user local folder for the application is not r=
emoved when we perform an update however that folder is specific to the ind=
ividual user and we can not share data from that folder. Does anyone know w=
hy the shared local folder is removed when we perform an update of an Ionic=
 2 application?
> I put a proof of concept application that simply writes a text file to th=
e shared local folder and the application local folder that can be used to =
see how the shared local folder is removed when we update the app.  The rep=
ository is located here: https://github.com/hoffmanjon/Cordova_Windows_UWP_=
Shared_Local_Folder  and includes a windows plugin to write to the shared l=
ocal folder.  You will need to set the groups policy as described in the li=
nk from the first paragraph of this description to get access to the shared=
 local folder.
