Have you ever said, "I can see the PC on the network but I can't access it"?
On Same Network Cross Platform
LocalSend (my new favorite) winget install -e --id LocalSend.LocalSend (zip the files for speed)
ShareDrop works well. It's a web platform. Not sure of limitations.
Send seems to work also.
*These have gone off the rails so just set up ssh, ftp or web server and get on with life.
Servers

Not On Same Network
Large Files and Auto Delete
... Wormhole (10gb self delete encrypted)
Rymdport uses Wormhole and is easier.
Small Files and Auto Delete (pain on Android phone)
... Sendanywhere
Large Files
... pCloud (May be best right now)
Large Files and Manual Delete
... Mega
Onionshare (Slow and may choke on large files but I like the concept.)
Receiving end needs to use Tor for the onion share address.
. . . Or Better yet SSH (Look Here)
Rymdport.exe (It can be portable also)
.. winget install Jacalz.Rymdport
It's a GUI for Magic Wormhole written in Go, so it's cross-platform.
It can transfer folders, not just files.
Search for the rymdport.exe, but CMD responds to rymdport and starts the GUI.
A custom passphrase can be used, but the pattern must start with a number. Example 123-abc
The number assigns a "room" on the server for communication. It's lightning fast.
Not sure about how it responds to size of transfers.
