FTPPUTFILE ERROR "Extended error code: 26"

I am trying to FTP a file and am getting this error message:

An error occurred while executing automation script: Line 7: Upload failed for "". Cannot open source file "c:\temp\test.txt" for reading: no such file or directory. Extended error code: 26.

Here is the line 7:
FTPPutFile( ftp_server, ftp_username, ftp_password, "C:\\temp\\test.txt", "/temp/test" )

Your help is appreciated.

Are you sure you have that file? No spelling errors in the name?

Thanks for the follow up. File is present and spelling is correct.

I figured it out. I had to use 2 forward slashes in the destination path:

This works: FTPPutFile( ftp_server, ftp_username, ftp_password, "C:\\temp\\test.txt", "//temp//test" )
This doesn't: FTPPutFile( ftp_server, ftp_username, ftp_password, "C:\\temp\\test.txt", "/temp/test" )

I fing this strange because I can use just 1 forward in the path when doing an FTPDir:

This works: FTPDir( ftp_server, ftp_username, ftp_password, "/temp/*", return )

Do you know why this is?

Thanks.

I am not sure why you need double slashes in //temp//temp. Is /temp/temp is a directory name or file name? The last parameter is supposed to be file name.

//temp//test

temp is the directory and test is the file name
