thnks for replying adatapost ...
but filesystemwatcher class only notify about changes in file and rename,delete,updated etc...

If i opened a file and closed without any changes and without doing anything than it's not notifying ...

so wht i want is ... i want notification for opening any file from my computer ... just opening files nothing else ...

FileSystemWatcher notify when any file created,deleted,rename or changed in given directory ...

You skipped links at post #2.

Text from MSDN link -
Changed — raised whenever changes are made to the size, system attributes, last write time, last access time, or security permissions of a directory or file.

as written ...

when last access time changed ...

but when i just open file and close without doing any thing ...
last access time is not going to change ..
is there any setting for this??

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.
To enable Last Access time updates open Registry Editor by typing regedit in Search input on Start Menu, locate HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem path entry and change NtfsDisableLastAccessUpdate value data to 0

Its already set to zero ...

now here time is 3:47 and i openedfile ..
but still showing me .... same as previous

[Geekitygeek]

So the registry was already set to zero? If you changed it recently, have you rebooted since?
If that registry value is set then i'm not sure why your files aren't updating : /

[crazyboy]

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 ...

[Geekitygeek]

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.

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

[Geekitygeek]

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 :)

[crazyboy]

yahh ..
i want it in my whole system
