System Volume Information

[TyBreaker]

Hi, I'm iterating through the folders on my system and am getting an
exception with "System Volume Information". Obviously it's a region I'm
not supposed to access so I'm trying to filter it out by checking for
the folder name before trying to use it:

If Folder.Name <> "System Volume Information" Then
GetFolderDetail s(Folder)
End If

But for some reason the if statement is not matching and I'm getting a
run time exception within my GetFolderDetail s because it is trying to
access the files in that folder. Can anyone explain why it doesn't get
caught by my if?

Re: System Volume Information

First of all, what is the value of Folder.Name when you hit the folder in
question?

I notice that I can access the 'System Volumne Information' folder on my
stystem drive but not on any of my other local hard drives where I get an
'Access Denied'.

Wrap your GetFolderDetail s(Folder) call in a try catch and handle the
exception.

Well according to the break point I have in my GetFolderDetail s routine,
the argument passed to the routine is the string "System Volume
Information" which is why I'm puzzled that my if statement doesn't catch
it. I shall double check with some debugging output.

If I have to use Try...Catch I will but I dislike that particular
construct as it tends to hide where errors are coming from so was hoping
to use an if statement to make it obvious as to why I did it.

Re: System Volume Information

Hello TyBreaker,

There can be a number of folders you can't access on any volume. Even the System Restore folder can have a different name than System Volume Information.
So you should trap any exception while accessing the file system. In your case, you can use something like this:
Try
GetFolderDetail s(Folder)
Catch ex As UnauthorizedAcc essException

'Do something, like maintain a list of inaccesible folders.

End Try



Regards.
