Manually transferring files

Hi guys,
I'm a Pleco heavy user who cannot live without it anymore since I arrived in China.
Some days ago I needed to wipe my android and Pleco refused to export my cards. So I backed up all Pleco folder.
My cards are very important to me and I want to keep using them.
Please, which file/folder do I need to copy from my backup, to which folder, of this new one?
I will appreciate a lot any help!
