WinSCP vs. CoreFTP and not being to see files

Question

I'm using FTP protocol on port 21 (not SFTP or anything else).

Using Core FTP LE, I connect to the server in question and I can see all the files in the directories

Using WinSCP, I can connect to the server and I can see the folders; however, files are not listed.

Any idea what the problem could be? It can't be a security issue, given I can see the files using Core FTP.

Answer 1

The problem had to do with the version of WinSCP (4.2.7); after the upgrade to 5.5.1 I can now browse through the files.
