WinSCP Session.EnumerateRemoteFiles does not work with mask with time constraint

Question

I'm trying to get the files from the SFTP server. The goal is, to get files newer than 24 hours.

This mask works. The count returns 9018.

var filesCount1 =
    session.EnumerateRemoteFiles(
        serverPath, "*.xml", WinSCP.EnumerationOptions.None).Count();

This mask does not work. The count returns 0.

var filesCount2 =
    session.EnumerateRemoteFiles(
        serverPath, "*.xml>24HS", WinSCP.EnumerationOptions.None).Count();

How can I fix it? I want to get file one by one, because I need to do some validation before the download.

As documented, Session.EnumerateRemoteFiles supports simple Windows wildcards only:

But you can simply filter the enumeration that the method returns:

DateTime limit = DateTime.Now.AddDays(-1);
var filesCount1 = 
    session.EnumerateRemoteFiles(
        serverPath, "*.xml", WinSCP.EnumerationOptions.None)
    .Where(file => file.LastWriteTime > limit)
    .Count();

Note that this counts "files newer than 24 hours", as you asked for. What is not what file mask >24HS means. So I'm not sure what exactly are you after.
