Determine if a directory can be moved on NTFS
I have a directory that contains lots of files in a complex tree of sub-directories. If I try to move that directory into a another directory on the same partition, that operation could theoretically take constant time - a rename operation, basically. - as long as none of the files in the source directory are in use and there are no sec...

Getting Extra Information From WinAPI File Change Notifications
The MSDN has a pretty good example of getting notified when a file or directory is changed. However, I can't find any way to get extra information such as the user/machine name associated with the change notification. For example, I've setup a share X:\Foo from my machine. I would like to log the user/machine names that make changes t...

NTFS structure and error analysis
This may sound like a serverfault question, but it isn't. It is about data formats of NTFS. Here goes. I have a corrupt disk drive. It's flashes in RAID, but it doesn't matter.

Blocking write locks with transacted NTFS
According to the MSDN documentation, transactional NTFS doesn't seem to allow one to block on opening a file for write - instead the open operation fails with ERROR_SHARING_VIOLATION. I'd like to block on writes instead - how can I do this? Ideally I'd like the following properties for the solution: Works over a network share (so no l...

Are Extended-Lenght Paths safe to use?
I just stumbled on this article on MSDN that says a path can be 259 characters + NUL termination, but if you prefix it with "\\?\" WinAPI allows you to use the maximum total path length of 32,767 characters. Eager to see it working I tried using that prefix from Explorer (On XP SP3) but it doesn't work at all (on any path). If you...
