QRServ - HTTP File Transfer

QRServ takes any selected files on your device and makes them available through its own HTTP server at an unused port number. The selected files can then be downloaded via web browser on another device and/or software that allows file downloads over HTTP from QR codes.
Devices involved would need to be on the same network (i.e. access point, tethering [no mobile data required], VPN [with a supported configuration]).

Features:
- QR Code
- Import via sharesheet
- Multi-file selection support
- In-app and via sharesheet
- Selection is put into a ZIP archive
- Tooltip when press and holding on the resulting archive file name will reveal the originally selected files
- Share option
- Show and hide filename in download URL path
- Long press the share button to toggle
- Various IP addresses from different network interfaces can be chosen
- HTTP server uses an unused ("random") port
- Supports various languages: English, French, German, Hungarian, Italian, Polish, Portuguese, Spanish, Russian, Turkish

Important:
Please note that you should have sufficient internal storage to make a copy of the same file(s) as it is stored into QRServ's app data storage rather than being directly accessed (as to combat MITD attacks and work with later Android restrictions).
To clear the resulting file(s) out from the app's own storage, either shutdown the server or relaunch the app after forcefully stopping it. Making another file selection will remove the previous data but that is after the file selection had been stored during the import process so ensure you have enough internal storage for that as well.

Permission usage:
- android.permission.INTERNET -- Collection of available network interfaces and port binding for the HTTP server
- android.permission.READ_EXTERNAL_STORAGE -- Read-only access to emulated, physical SD card(s) and USB mass storage

QRServ is open source and available for desktop.
