Thanks for the prompt reply.
I tried using Size property - It gives me error that This is not a standard FTP command.
I checked in the edtftpnet document there it is mentioned - Get the size of a remote file. This is not a standard FTP command, it is defined in "Extensions to FTP", a draft RFC (draft-ietf-ftpext-mlst-16.txt) . What is this "Extensions to FTP".
Please let me know.

If I use DIR it gives me if files are present in that directory. I want to know if a specific file()with specific filename) exists or not.

Is there any other easier way to find out if a particular file exists on the ftp server.


Also DirDetails lists a directory's contents as an array of strings. I wanted to know how to find out if a particular file exists.

Answer 3

Is there a way to find out directly if a particular file exists on the ftp server other than DirDetails?.
DirDetails gives a list of filenames present in the ftpserver directory.
I needed to find out if a particular file exists in a particular directory.

That really is one of the easiest ways.
