DriveMaker Freeware converts an FTP site into a drive letter, enabling users to access the files on their FTP server as if it were on their PC. Compatible with various software, it simplifies accessing files on an FTP server.

What's even better is that the basic version of DriveMaker is completely free, even for commercial purposes. However, it's important to note that redistribution of the software is not allowed. You need to download DriveMaker each time from the link provided on the page.
DriveMaker works on Windows Server 2008 or Vista and later, making it a great option for those using either of these platforms. Unlike FTP clients that require you to download files before editing them, DriveMaker maps FTP sites to a virtual local drive. This means that you can edit files directly from the drive without the need to download and upload them back to the server, thereby avoiding the inconvenience and potential data loss associated with this process.
Overall, if you're looking for a reliable way to access and edit files on your FTP server, DriveMaker is definitely worth considering, especially considering its free and commercial-friendly nature.
