Hi Milford,
Im not sure if this applies to the ITC, but maybe it will get you pointed in the right direction. Robert Abrams has a FTP class here in the files section and he had experienced a similar problem and this is what he says:

Some people have had problems setting up auto Ftp programs that retrieve the same file on a recurring basis. This was because, after the first time the file was downloaded, the file was put into cache and subsequent calls for the file retrieved the file from the cache and not the FTP server. The file date was set to the time of the latest download attempt, adding to the confusion.

So, there should be a way to disable caching with the ITC.
Good Luck.
Jon

>I'm using the Internet Transfer Control to download files everyday from various FTP servers. The files that are supposed to be overwritten everday aren't (the new files, with new filenames, come in fine). I have to delete them from the local machine first. Any ideas?
