Welcome to AutoIt and the forum,

is this a fileserver on an internal network or a server you access using TCP/IP (internet).

It then depends on the services the server provides (FTP, HTTP).

@water first of all thank you for quick reply , yes its ftp need to check using ftp.

Please check the FTP UDF in the help file, section User Defined Functions -> FTPEx.

To check a file for existance you could use _FTP_FileGetSize. Doesn't put too much overhead on the server and the script and returns an error if the file doesn't exist.

can you please provide me a liitle code for it please I am newbie to autoit..

Global $server = "servername or IP.address.of.your.server"
Global $username = "usernmae"
Global $pass = "password"
Global $Open = _FTP_Open('MyFTP Control')
Global $Conn = _FTP_Connect($Open, $server, $username, $pass)
Global $FileSize = _FTP_FileGetSize($Conn, "your filename")
Global $Ftpc = _FTP_Close($Open)

Error checking has to be added by you Edited October 9, 2012 by water

thank you very much for this bro

[water]

Hope it works.

Just did a q&d copy from the help file.

You're not getting a refund on that fish water =P

[water]

It's a start, so just half of a fish

The OP still has to check the result of _FTP_FileGetSize and code the rest of the script. Error checking is also missing.

Global $server = "servername or IP.address.of.your.server"
Global $username = "usernmae"
Global $pass = "password"
Global $Open = _FTP_Open('MyFTP Control')
Global $Conn = _FTP_Connect($Open, $server, $username, $pass)
Global $FileSize = _FTP_FileGetSize($Conn, "your filename")
Global $Ftpc = _FTP_Close($Open)

Looking for something like this myself. Changed this a wee bit to add a simple msgbox

#include
Global $server = "myserver"
Global $username = "myusername"
Global $pass = "mypassword"
Global $Open = _FTP_Open('MyFTP Control')
Global $Conn = _FTP_Connect($Open, $server, $username, $pass)
Global $FileSize = _FTP_FileGetSize($Conn, "irreg.txt")
;Global $FileSize = _FTP_FileGetSize($Conn, "session.asp")
If @error Then
MsgBox(0, "", "Error: " & @error)
Else
MsgBox(0, "", $FileSize)
EndIf
Global $Ftpc = _FTP_Close($Open)

Works great, except for zero-length files. I get the same error (-1) that I get for a non-existent file.

Does anyone know an easy workaround?

[water]

If you get -1 you could try to read the file using

$result = _FTP_FileRead($hFile, 1)

I assume you get @error = -1 (End of file) and $result is set to "".

If the file doesn't exist you should get another value for @error.

Could you give this a try?

OK using this code:

$handle = _FTP_FileOpen($Conn, $filename)
$result = _FTP_FileRead($handle, 1)
MsgBox(0, "", "Error: " & @error & " Result: " & $result)

- Empty file: Error -1 Result 0

- 80k text file: Error 0 Result 0x30

- Non-existant file: Error 2 Result 0

So it looks like if there's an empty file in the mix, I'm thinking it's probably better to forget this and read all the filenames via _FTP_ListToArray() and check for them there.
