can anyone help explain what might happen to a .NET application if file system crash? Simply put, should the apps pop up warning/error reminding that file system is carshed? How does your apps deal with file system crash?
Please help answer, many thanks.....

What do you mean by "file system crash", and how do you think the app could recognise it?
One of these days I'm going to think of a really clever signature.

for example, a designated folder got changed, not able to write into it, the system shall pop up error message, right? so I have to make specific error exception/message for this kind of case, otherwise the system just gave general error message, am I right?

You would need to implement FileSystemWatcher, take a look at these links[^].

As the inability to save to a certain location is a predictable exception (e.g. the user attempts to save into the Windows folder on Windows 7 when running with normal permissions), it's always a good idea to protect against this type of exception.

In general - no.

Whatever the business requirements suggest and reasonable extrapolation from that.
For example I don't try to do anything at all about the file system filling up for a server. Can it happen? Yes. If it does what can I do? Nothing. I do however expect that any reasonable operations setup would take into account file system monitoring.
As another example if I can't read a configuration file that the server requires on start up then besides logging an error I can do one of the following
- Start with default values.
- Exit the server.
The choice depends on what was supposed to be in the configuration file that I was reading.
(Note that a logging solution MUST be implemented such that a logging failure does not stop the application from running.)
A stand alone user application should probably do something different. If it cannot read/write to the fle system then it should report that to the user.
