What methods exists for downloading files from a remote computer's harddrive?

6 posts in this topic

Prior to posting this question, I have experimented with using FileExists, InetGetInfo and InetGet/InetClose functions to test downloading files into my application folder, in case if my file did not already exist.

In my case, I was able to pinpoint to a very specific web address, eg.), etc. and then check/download the file.

Now my question is, instead of checking from a hardcoded URL, is it possible to:

1. Do a check against the IP address of a remote computer, eg.) my friend's or colleague's desktop computer

2. After checking the IP address if valid and can be connected to, access the computer's hard drive location, eg.) that machine's C:specifiedFolderspecifiedFile.txt

3. Download a copy of that file into a local computer

I did read ('?do=embed' frameborder='0' data-embedContent>>) but that was what I accomplished earlier, so now I am not sure if I were to change the method of file retrieval, what changes are necessary?

You cannot access remote computer's files unless you both are in either local or vpn network

If you have a local or vpn connection, the easiest thing i can think of is maping the network path to a temporary drive, search for the file (or if you know where it is - use that) and then copy it to local drive in a desired location. 

EDIT: acutally it is possible, but idk who will be that stupid to expose his computer to the internet via his real IP if he have one 

EDIT2: another way is if he can run an http/ftp server and you download it from there, but for me that's stupid and insecure, but inetget should work

post some more details on what you are trying to do

I am writing a program for use internally within a local network.

Initially, the program would look for a copy of an Excel file locally and if it could not found, the program throws a generic error message; otherwise, just export data into the local Excel file.

Now, I am making changes to instead throw a File Not Found message, I experimented with fetching a copy from my testing Dropbox account into the local drive. Seems fine so far, so I am switching to getting a file from a computer within a local network instead. That's when I am looking for either a simple solution of either getting a common network path, or take authentication/security into consideration before connecting.

Check the help file for :




play around with them and you will make it. If i have time i might write an example. It should not be that hard, but depend on your skills :)

There you go, today i'm doing everything else than what i need to do lol

NOTE: this is not tested, i have no local share to try it

#include <MsgBoxConstants.au3>
#include <FileConstants.au3>

Local $dLetter = "Z:" ; drive letter to use when mapping. NOTE: must not exist
Local $nShare = "\\computer-name-or-IP\shared\folder\" ;remote share, where the backup file can be found
Local $sFilePath = "c:\path-to-my-file\" ;local path of where the file should be
Local $sFile = "my-file.something" ;the file we are searching for on our local hard drive
Local $sUsername = "Username" ; username for the remote share
Local $sPassword = "Password" ; password for the remote share
Local $sFlag = "0" ; A combination of the following: 0 = default; 1 = Persistent mapping; 8 = Show authentication dialog if required


Func Example()
    Local $iFileExists = FileExists($sFilePath)
    If $iFileExists Then
        ConsoleWrite("The file exist" & @CRLF)
        sleep(100) ; you can remove this
        ConsoleWrite("The file does not exist" & @CRLF)
        Local $tVar = DriveMapGet($dLetter)
            If $tVar = $nShare Then
                ConsoleWrite("Drive is mapped properly" & @CRLF)
                ConsoleWrite("Drive is not mapped properly" & @CRLF)
                DriveMapDel($dLetter) ; just in case it's mapped somewhere else
                    If @error = 1 Then
                        MsgBox($MB_SYSTEMMODAL, "Error","There was an error mapping the drive. Error : " & @extended,5)
                    ElseIf @error = 2 Then
                        MsgBox($MB_SYSTEMMODAL, "Error","Acces to the remote share was denied",5)
                    ElseIf @error = 3 Then
                        MsgBox($MB_SYSTEMMODAL, "Error","Device " & $dLetter & " is taken.",5)
                    ElseIf @error = 4 Then
                        MsgBox($MB_SYSTEMMODAL, "Error","Device name " & $dLetter & " is invalid.",5)
                    ElseIf @error = 5 Then
                        MsgBox($MB_SYSTEMMODAL, "Error","The remote share is invalid/unreachable.",5)
                    ElseIf @error = 6 Then
                        MsgBox($MB_SYSTEMMODAL, "Error","The password provided is invalid.",5)

        Local $fCopy = FileCopy($dLetter & "\" & $sFile, $sFilePath & "\" & $sFile, $FC_OVERWRITE)
            If $fCopy = 1 Then
                ConsoleWrite("Copy successful" & @CRLF)
                MsgBox($MB_SYSTEMMODAL, "Error","Error copying the file : " & $sFile & "." & @CRLF,5)


Func mystuff() ; everything in this function will be executed only if the file exists

Edit this to suit your needs, and if you feel like it will work, mark this as solved, so this can help in the future if more people need it :)

EDIT: fixed small non-fatal errors

EDIT: ^%^!&@*#^!@*E&Q^@ this editing, srsly

In general it would be better from a security point of view to have the target computer upload the file either to a mapped network share, or by ftp to a webserver, at regular intervals. This can be accomplished with a fairly simple script. You can save on bandwidth if you do a CRC (or just use the modified date) and only reupload if the file has changed.

Then you can download it from there with autoit commands, wget or commandline ftp. Or, just browse to it manually.

Other advantage is that you don't need to know the computer's IP address, nor does it have to be static, since the computer 'pushes' the file to you.

Another option might be rsync which is basically a Linux app for file transfer over TCP, but various Windows ports exist, eg DeltaCopy.

      Hello there,
      I am using the function InetGet example in the help files on a website and getting the error 13. First, I searched the help files and the forum for a list of errors to consult to no avail. I suspect this is a 400's server reply based error but it would be nice to get more info about it.
      Please help, thanks.

      Hi Guys, I need help. I have searched the forum before posting and i couldn't find anything. The code below works fine when downloading files from "http" sites, but when trying to download from "https" sites, no files are downloaded. I tried different sites and I experience the same problem everywhere. Is there something I'm missing or doing wrong? Please note that I'm not a programmer and I'm new to this. I'm just using logic wherever i can to get things done. your help will be highly appreciated.

      First script here. Thanks for taking the time.
      I want to download a file from my dropbox or other cloud file host and I want autoit to read the file and proceed.
      Here are the references I've gone through, it's just I'm not familiar yet with autoit so I'm looking for advice:
      How would I start out downloading a text file from dropbox and if in the file there is a 1 then it will proceed with the rest of the script if there is a 0 or if the file cannot be downloaded I want it to just end.
      Thank you for taking the time to read this and I apologize in advance if this seems very trivial for some but this is my first script and I'm hoping this is the correct place to ask this question.

      here's another UDF for the serial port. It is very similar to CommAPI using kernel32.dll, but all code is packed into a single file without any dependencies, not even using WinAPI.au3. It differs from existing UDF that it doesn't allow a timeout when reading, instead it always returns immediately, either with the requested amount ob bytes read or with a failure status. And of course there is a function provided to query the amount of available bytes in the receive buffer. The reason behind this design decision: You can do 1000 other things in the main loop while checking from time to time if enough data bytes arrived. There's no point to block the program waiting for the serial port.
      It is currently a work-in-progress, as I didn't test all functions yet. The code was developed and tested on Windows 7 64 bit.  The ComUDF-Tests.au3 shows some tests and basic usage of the UDF. Maybe there's no reason to use this UDF, given the existence of the others UDFs, but I did it to get to know DllCall better - I use structs no only to pass but also to get data back (I don't use the array returned by DllCall to read that data, unless required). You're welcome to test it on older and newer Windows versions.
      Here's a list of the implemented functions:
      ; _ComListPorts ; _ComOpenPort ; _ComSetTimeouts ; _ComClosePort ; ; _ComSetBreak ; _ComClearBreak ; _ComGetInputcount ; _ComGetOutputcount ; _ComClearOutputBuffer ; _ComClearInputBuffer ; ; _ComSendByte ; _ComReadByte ; _ComSendBinary ; _ComReadBinary ; ; _ComSendChar ; _ComReadChar ; _ComSendCharArray ; _ComReadCharArray ; _ComSendString ; _ComReadString ; ; __ComClearCommError ; __PurgeComm Maze
