Check if file exists before download

2018-04-25 10:50

Hello,
i want to check if a file exists before download it without using .NET assembly. I try this:
if exist c:\upload\test.txt winscp.com /script=upload.txt
from your documentation at https://winscp.net/eng/docs/guide_automation_conditional#scripting
but it returns an error that command if is not recognized. Could you help me plz?
Thank you!

If you are using .NET assembly, use Session.FileExists method:

I don't want to use .NET assembly. I have mentioned that in question! I want to use a simple bat file.

OK, I've misunderstood the question.

Though it's still confusing. Why are you trying to check a local file before calling WinSCP with upload.txt script, if you are going to download a file?

i use get command to download a file from a server...But everytime the file doesn't exists i get an error message. So i want to firstly check if the file exists and then use get command to download it!

I strongly recommend you to use WinSCP .NET assembly.

If you do not want to use it, see

script for checking if file exists is not working

2020-10-29 01:33

hello-
so the situation is to check that a file exists first, if it does then continue on to the next steps of the ssis package. if the file does not exist then exit and stop. i used the script from https://winscp.net/eng/docs/script_checking_file_existence#scripting and when i run it i get an error message...

Script: set REMOTE_PATH=/Home/blahblahblah/CustomContractImport/Import/Importcontract.xlsx
Script: Unknown command 'set'.
Script: Failed

is this set command not right? is there something that was not in the original script that was not correct? this seems like a simple script even for a noob like me but apparently it is not. :( can someone help me?
the scriopt is...

# Automatically abort script on errors
option batch abort
# Disable overwrite confirmations that conflict with the previous
option confirm off
# Connect to SFTP server using a password
open sftp://blipblahbloop:EQFz7I:igL13@transfer.filecheck.com/ -hostkey="ssh-rsa 2048 fc:0f:92:5d:98:d4:77:65:2a:eb:a2:fa:0d:27:0a:7f"
# Upload file

echo off
 
set REMOTE_PATH=/Home/blahblahblah/CustomContractImport/Import/Importcontract.xlsx
winscp.com /command ^
    "open mysession" ^
    "stat %REMOTE_PATH%" ^
    "exit"
 
if %ERRORLEVEL% neq 0 goto error
 
echo File %REMOTE_PATH% exists

exit /b 0
 
:error
echo Error or file %REMOTE_PATH% not exists
exit /b 1


# Disconnect
close

The "script" in the article is a Windows batch file, not WinSCP script. You cannot put it into WinSCP script.
