I'am testing your library. I am mainly interested in knowing the
access attributes of directories in the local(C:\) or shared unit(W:\)
of my system.

Using your script with 'c:\\' I get an error message saying... 'file
exists but it is a directory' and I cannot go any further.

Of course, the problem is that I am using "fs.file" when I should be
using something different.

Either use fs.dir (if you know it's a directory) or fs.entry (if it
could be a file or a directory; the code will dispatch to the right one).

If you only want the directories immediately some directory,
you could do this:

<code>
from winsys import fs, security

root = fs.file (sys.executable).path  # or fs.dir ("w:/") etc.
for d in root.dirs (ignore_access_errors=True):
    print (d, "=>", d.security ()) # or whatever

If you want to walk the tree of directories looking at permissions, then:

<code>
import os, sys
from winsys import fs

root = fs.file (sys.executable).path
for dirpath, _, _ in root.walk ():
    print (dirpath, "=>", dirpath.security ())

</code>

Reading the doc I have found that I should be using os.walk(...),
which works, but then I cannot use fs.file

In fact, even if you did for some reason use os.walk, you can
easily wrap the returned filenames using fs.entry:

<code>
import os, sys
from winsys import fs

root = os.path.dirname (sys.executable)
for dirpath, filenames, dirnames in os.walk (root):
    print (dirpath, "=>", fs.entry (dirpath).security ())

</code>

Tim,

One of your scripts still does not work on my system:


==>  If you want to walk the tree of directories looking at

<code>

root = fs.file (sys.executable).path
for dirpath, _, _ in root.walk ():

</code>

However, I get the following error:

Traceback (most recent call last):
   File "C:/Local/test4.py", line 5, in<module>
     root = fs.file (r'W:\FRIB\ELPR\$DATA\DPT-FINANZAS').path
   File "C:\Program Files\Python31\lib\site-packages\winsys\fs.py",
line 1775, in file
     raise x_fs (None, "file", "%s exists but is a directory" %
filepath)
winsys.fs.x_fs: (None, 'file', 'W:\\FRIB\\ELPR\\$DATA\\DPT-FINANZAS
exists but is a directory')

That is, I am interested in looking for directories, but the problem
is that the path is a directory.

I'm sure there must be some way to get around this problem.


Replace fs.file by fs.entry: the latter detects automatically whether
it's looking at a file or at a directory. I used fs.file in my example
because I *know&* what sys.executable must be a file (python.exe). In
your case, either use fs.dir if you know it's a directory or fs.entry
if it could be either. (Obviously fs.entry must do some work to determine
which it is, so you can optimise slightly by specifying fs.dir / fs.file)
