Is there a way to only get files in a date range over FTP?

Question

We have a sync process that is daily making sure we have all files from a remote SFTP but as time goes on, we're having to download all files just to check that we already file copies in the database by content hash.

Is there a way, let's say using SSH.NET or WinSCP, to only do this process with files in the last two weeks?

It's bit unclear if you want to use SFTP or FTP. In any case, WinSCP supports both. — Martin Prikryl, May 28 '20 at 18:24

I'd use FluentFTP

using FluentFTP;
using System.Linq;

.
.
.

DateTime min = ...;
DateTime max = ...;

using (var conn = new FtpClient("address", "user", "password"))
{
    conn.Connect();

    var files = conn
        .GetListing("/path", FtpListOption.Recursive)
        .Where(item => item.Type == FtpFileSystemObjectType.File
                    && item.Modified >= min
                    && item.Modified <= max);

    foreach(var file in files)
    {
        ...
    }
}

You can use Created instead of Modified

While OP is indeed bit inconsistent about the use of SFTP and FTP terms, I believe he actually wants to use SFTP, not FTP. So FluentFTP won't help. — Martin Prikryl, May 28 '20 at 18:23
