Excuse me, the announcement application program is accessing this
folder from time to time to play the appropriate voice announcement
file . As there are a huge number of voice files inside this folder,
so I need some way to trace to see which file is being accessed when
hearing the corrupted voice file . I tried for your "watch" &
"inotifywait" utilities but I didn't see any log even when
intentionally trying to ftp some files into this folder. It seems that
my previous explanation of the problem was not so clear. Sorry again .
What can I do to find an appropriate trace method for my case in your
opinion ?
