Happened to me as well with Indy 9. After digging in the sources, I found
the the DOS Directory parser does not handle large files well. Looks like
the file size "spills" to the left and confuses the parser. The result is
that the FTPList format is not identified, an exception is raised and
nothing gets parsed in DirectoryListing.
You could override OnCheckListFormat to force the format to flfDos or
whatever you need.
Perhaps someone could enter this as a bug
