tigerclawn82 commented 8 years ago

Hi, Would it be possible to add NTFS Change Journal support? There's is example given in C++, if you can just guide i can also do that. Any help would be appreciated.

Thanks

You probably already know this but if you can keep your program running all the time, you can use something that's already implemented, mature and cross-platform for change event notifications: What about https://github.com/go-fsnotify/fsnotify?

The answer to your question is "yes" it's possible. In fact probably pretty easy. Calling CreateFile (according to https://msdn.microsoft.com/en-us/library/aa365259(v=vs.85).aspx) followed by using this: https://msdn.microsoft.com/en-us/library/aa364558(v=vs.85).aspx

I want to use this in a backup utility so watching for files changes when size is large eg:900GB, it would not scale well. USN Journal, it can work well as it already keeps tab on changed files so i can query USN Journal and copy files that are only changed.

Thanks for the https://github.com/go-fsnotify/fsnotify, i reviewed that and they are also not supporting USN Journal at this time.
