Directory Writable Question

[heimer]

I am attempting to determine whether or not a selected directory is
writable.
I am using Active Tcl/Tk 8.4.5 on WinXP and accessing directories on both
Win and Unix. I let the user select a directory using tk_chooseDirectory. I
want to determine if I should disable a separate button that would call a
proc that copies some files to that directory.
I tried 'file writable $dir' and always get back 1, never 0 - even though I
have selected directories that I know I have no write access to.
I have also tried 'file stat $dir' and extracted the mode from the array and
always get the following
result: 16868
I have also tried 'file attributes $dir -readonly' and always get the value
0
I am at a loss.

You say you are sure you have no write access to some drives but are you sure Tcl also doesn't. Just for jollies, try writing to one of them from the Tcl shell. Since Tcl was probably installed under administrator, it could be that Tcl has more access than a user does.

Just a thought.

Thanks for the reply.

I tried to create a file under the selected directory and
failed because I didn't have permission - as expected.
