Subject Re: [VFS] How to override a FileContent / FileContentInfo provider for an existing filesystem?
Date Mon, 25 Sep 2017 15:09:59 GMT
Hi Carl,

WRT DataSource, this is a JDBC interface, which does not seem appropriate
for a file system. Or do you mean javax.activation.DataSource. Apache
Commons VFS was started a long time ago and not adapted to newer JREs in
this area (obviously.)
