Useful - Once I was able to select a folder
I was trying to use this to copy some files over from my iPad to my laptop and had some difficulty getting it to work (probably due to my own inexperience with iOS) so I'm sharing the steps I had to take in case it saves anyone else some trouble: I was unable to select a folder from within the app, the "Open" button in the files popup was disabled for any folder I navigated to. Instead I had to open the Files app and use the "Share" option for the folder I was interested in serving with Tiny Server. Also, this is almost certainly an issue with my router but I had to switch to the 2.4 GHz network for my connection to go through (however connecting the device to itself in Safari was never a problem) otherwise the connection would hang and eventually time out.
