You can read the file, then put it into a string, then send it over rednet. Somethign like this:

local readFile = fs.open("<filename>", "r")
local fileTab = {}
repeat
  table.insert(fileTab, readFile.readLine())
until readFile.readLine() == nil
readFile.close()

rednet.open("<side>")
rednet.send(<ID>, textutils.serialize(fileTab))
rednet.close()

That will send the file in a table, line by line.

rednet.open("<SIDE>")
local id, msg, dist = rednet.receive()
local contents = textutils.unserialize(msg)
local saveFile = fs.open("<FILENAME>", "w")
for i = 1, #contents do
  saveFile.writeLine(contents[i])
end
saveFile.close()

That should receive the file and save it.

Thanks is there any way I can make it save as anything from the sending pc so I could make it save as whatever I want from the sending computer

Im trying to write a program to send and receive messages, but its not working.
Im trying to use local id = read() to save what number you type for the computer id youre sending to, but when i do
rednet.send("..id..","..msg..") it says the id needs to be a positive number. I know that this should replace id with the number, but it doesnt work.

If you use rednet.send("..id..","..msg..") and id is 3 and msg is "Hello world!", you will send the message "..msg.." To computerid "..id.." and not the message "Hello world!" To computerid 3 (remember how you shall define variables (" shall not be used))

Use rednet.send(id,msg) (you do not need .. If you do not shall have both plain text and variables together).

It still doesnt work. It keeps saying rednet:347: positive number expected.

os.pullEvent = os.pullEventRaw
term.clear()
term.setCursorPos(1,1)
rednet.open("top")
print("Broadcast or personal message?")
input = read()
if input == "broadcast" then
 term.clear()
 term.setCursorPos(1,1)
 write("Message:")
 local msg = read()
 rednet.broadcast("'..msg..'")
 print("Sent")
 sleep(2)
 os.reboot()
elseif input == "personal" then
 term.clear()
 term.setCursorPos(1,1)
 write("To:")
 local id = read()
 write("Message:")
 local msg = read()
 rednet.send(id,msg)
 print("Sent")
 sleep(2)
 os.reboot()
end

You were not making the ID a number, so here is the correct code.

Spoiler

local oldPull = os.pullEvent
os.pullEvent = os.pullEventRaw
term.clear()
term.setCursorPos(1,1)
rednet.open("top")
print("Broadcast or personal message?")
local input = read()
if input == "broadcast" then
term.clear()
term.setCursorPos(1,1)
write("Message:")
local msg = read()
rednet.broadcast(msg)
print("Sent")
sleep(2)
os.reboot()
elseif input == "personal" then
while true do
term.clear()
term.setCursorPos(1,1)
write("To:")
local id = tonumber(read())
if id ~= nil then break end
print("ID must be a number.")
sleep(1)
end
write("Message:")
local msg = read()
rednet.send(id,msg)
print("Sent")
sleep(2)
os.reboot()
end

Thanks. That actually works. Now I need to make them able to receive.

Casper hasn't been on in ages. Tbh, I've never seen him post, besides forum guidelines and whatnot.
