Yes, thats possible, head to https://minehut.com/dashboard/
Make sure your server is online, and if not you can activate it from your panel.
Then go Edit Server then head over to File Manager then locate to the file you want.
There is no download file button on minehut that I am aware of
However you could just copy and paste the contents of the files single handily or something like that, ye idk.
gtg for dinner.
