It works in WP 3.8.
But as 3.8 changed all the admin fonts, you have to resize the windows when working with files because the formatting is all messed up.
The plugin author doesnt really support this plugin anymore and threads here never get answers or help.
I wish I never installed it. No support, buggy, no ability to export, doesnt work well with large files, etc..........
So if you find a better plugin let me know. :)
