dlcnt files , how open them

days ago downloading a game i've found a "gamename.zip.dlcnt" file large 1 byte , yeah weird , anyone know how open or use these files with this extension ? thank you everyone

that seems to me like its a partial download file created by a download manager

Replying to #2

yeah i used jdownloader 2 for download from mega but on mega too in the browser show this extension and is still large 1 byte so i doubt is the download manager fault

if interested , i've uploaded the file here http://s000.tinyupload.com/download.php?file_id=07841816084140322048&t=0784181608414032204877795 , if anyone know how open or use those dlcnt files , would be nice if could let me know , thank you
