We've been saying it for years: Without a doubt, the most difficult types of drivers to write for Windows are File Systems and File Systems Filter Drivers.

Fortunately, developing file system related drivers for Windows is one of our specialties.  And in the File Systems section of OSR Online we share with you what we've learned over the years through hard-won experience.  If you're a file system developer, reading the File System section can save you days or even weeks of time.

So, sure... File system and file system filter driver development is hard.  But, isn't it nice that it's a little easier with our help?
