I found a file on my external hard drive," .minidlna". I don't know what it is. It seems to have a log. It seems to connect to port 1900. I only use my external drive offline. I want to delete the .minidlna file and anything it does. But.... can I do that? Will I still be able to use my external hard drive? Will it still work? I have files on the drive that I don't want to lose. So WTF is it and can I safely get rid of it?
