Filedot to katrin

It seems like you may be referring to a specific transition between online file-sharing or file management systems, but "Filedot" and "katrin" are not widely recognized terms or platforms as of my last update. Could you please provide more context or details? Are these specific software tools, applications, or file management systems you’re asking about? Update (2025-12-20): It looks like you may be referring to a file transfer or a specific context involving "Filedot" and "Katrin." Could you please provide more details or clarify what you mean? Are you looking for information on how to transfer files, or do you have a specific topic in mind related to these names?
