[Users] Cross platform data for a newsreader and e-mail client

[Edward Diener]

I am looking for a news reader, e-mail cliient, supporting Linux and 
Windows, which supports the sharing of data between both OSs. In other 
words, on a shared drive ( NTFS partition ) I want to be able to have 
the data of the application accessible by both Windows ( 7, 8.1, 10 ) 
and various Linux distros in a multi-boot environment. I am not looking 
to access the data at the same time from different OSs, but just to be 
able to access the same data flawlessly when running Claws on Windows or 
a Linux distro.

Is this possible with Claws ?

I had been using Thunderbird, but after having problems sharing a TB 
profile between Windows and Linux distros I was told that this was not 
officially supported by TB. Therefore I am looking for a good 
alternative and found Claws. But I did not find the information on 
whether data can be shared across platforms, so I am asking on this 
mailing list before I start to use Claws.
