[asrmurthy1]

I could able to open few pdf files. The following message is appearing:

'The file could not be accessed.  Check your connection or make file name shorter.'

Some files do not show download option.

Moreover, I could not make Adobe Acrobat reader as default App.

'This app is set to open by default for some actions'.
