Naive question: would it be possible to copy txt files into the dokuwiki sphere via ftp?
That shouldn‘t be a problem. The wiki-pages are stored in the directory data/pages when you access with a ftp-client.
Be sure to use only lowercase filenames which have no spaces (use _ instead) or special characters like äöü or ß. Otherwise the pages won‘t be found by DokuWiki.
