Hi all, I am working on downloading files from FTPS. The server config should be correct, as I can read the files and folders in FTPS.

I also tried to download file with python, and it works fine. So I think it should not be an issue with the server.

Thank you for your help!

hI @Bachali

I Think you can try also with normal workaround in FTP Server like Right click Download for delete click Send Hot key Delete

Screen Scrapp and check Screescrapped variable.Contains any file with it like that

Just a suggestion and give it a try
