I dont know how to read it into a table :(/>If the file is a large read it into a table and use textutils.serialize() and textutils.unserialize() to convert it to a string and back to a table again after it is sent.

Well can you send a table via rednet?If the file is a large read it into a table and use textutils.serialize() and textutils.unserialize() to convert it to a string and back to a table again after it is sent.
Why on earth would you want to do that? You realize that the result of textutils.serialize() will be larger than the original file?

local tContents = {}
write("Enter program to send: ")
local fileName = read() -- example "startup" to send the startup file
write("Enter Computer ID to send to: ")
local toID = tonumber(read())
local file = fs.open(fileName, "r") -- open file as read only
repeat -- read the file line by line and insert into the table
line = file.readLine()
table.insert(tContents,line)
until not line
file.close()
local sContents = textutils.serialize(tContents) --change it to a string
rednet.send(toID, fileName..","..sContents) --send it with the filename in front of it
local id,msg = rednet.receive()
local fileName,sContents = string.match(msg, "(%w+),(%w+)") -- split the file name from the contents
local tContents = textutils.unserialize(sContents) -- change to table
local file = fs.open(fileName,"w")
for x=1, #tContents do -- write the file line by line
file.writeLine(tContents[x])
end
file.close()

Thanks, But i need to be able to have the sending computer triggered by a rednet message and send a full folder to the recieving computerTry this out. It should work, but I haven't tested it.Spoiler
Send computerlocal tContents = {} write("Enter program to send: ") local fileName = read() -- example "startup" to send the startup file write("Enter Computer ID to send to: ") local toID = tonumber(read()) local file = fs.open(fileName, "r") -- open file as read only repeat -- read the file line by line and insert into the table line = file.readLine() table.insert(tContents,line) until not line file.close() local sContents = textutils.serialize(tContents) --change it to a string rednet.send(toID, fileName..","..sContents) --send it with the filename in front of it
Receive computerlocal id,msg = rednet.receive() local fileName,sContents = string.match(msg, "(%w+),(%w+)") -- split the file name from the contents local tContents = textutils.unserialize(sContents) -- change to table local file = fs.open(fileName,"w") for x=1, #tContents do -- write the file line by line file.writeLine(tContents[x]) end file.close()
This is very basic and will not handle files in directories without some modification. Just a simple example to get you going.

local contents = h.readAll()
h.close()
rednet.send( id, contents )

Look into fs.list combined with fs.isDir, unless you want to create directories as well (then take a look at my file system Iterator in misc scripts in signature) and storing all the files in different table entries, then serialize the table and send. Receive, unserialize, loop through reading the table of files writing them to the computer.Thanks, But i need to be able to have the sending computer triggered by a rednet message and send a full folder to the recieving computer

Yes it preserves formatting. I always use read all, so that the handle is open for the shortest amount of time, then if I need a particular line I use my split string function in my Extended String Library to split it by \n to get a table of lines… Reason I do it this way is because if something happens and that file handle is still open, well it's annoying as hell!Will that keep the formatting? I've never really used readAll(). Got in the habit of using tables with reading files when I started having files edit themselves to set persistent variables.
