from febooti:
For improved file system performance Last Access time update in switched off in Windows Vista by default. Thus, Last Access time attribute is set upon creating file and not changed afterwards even if file is modified. However, it is possible to enable Last Access time updates if necessary.

now here time is 3:47 and i openedfile ..

If that registry value is set then i'm not sure why your files aren't updating : /
as i go through some msdn articlez ....
i come to know that in NTFS file system file last access time is updated per hour.
To speed up the disk access this is updated per hour. thts y file system watcher class is not getting notify ..
if any one having any another solution than please reply ...
It look slike what you want to do is far from simple and probably not possiblew from within the .net framework.
You could try looking into File System Filter Drivers.
yash
yahhh ..
i was knowing this solution but i m not having that much time to understand this, read it and implement.....thtts y i was asking for any other solution if possible ...
but now its okay ....
if i want to do thn i have to do with File System Filter
If you are only tracking files opened within your app you can use the open file dialog. But if you need to track when files are opened outside of the ap thats then only method i've found. Good luck :)
yahh ..
i want it in my whole system
