Access to a UNC path

Gloops 41

Hello everybody,

When I access to a path as a UNC path, and I need it as the current directory, is it mandatory to provide it a driver letter ?

Sorry I later realized that the used platform was not made obvious by the name of the forum : it is Powershell.

My script looks like this :

$source = Get-ChildItem "\Uc00006\d\Projets Visual Studio\Web"

foreach($d in $source)
{
$N = $d.Name;
$path = "D:\Projects Visual Studio\web\" + $N;
if((Test-Path $path)-eq $true){
$N + " OK";
}
else{
"not found : " + $N;
}
}

This version does not work (to Copy-Item), it was OK when I used SUBST to initialize the default path.

It looks like you're trying to see if the files in the shared directory exist in a local directory. Is that correct?

What value is in $N and what value is in $path when you execute the Test-Path?

Hum, that is what I shall have to do now, as I have got empty directories, where there were no directories at all before. Is there a IsEmpty property of something like that ?
If you see at the beginning of the script, $source is the parent directory, $d its descriptor, and $N the name of $d.
Then $path is the path where the file has to be found the other side, or copied to.

Well, yeah . . . I can read your code, but that doesn't mean I understand what your intentions are! Nor does it mean that I (or you) know whether or not what you wrote actually produces the data you expect. That's why I asked what you were trying to accomplish and what the actual data was.

If you have empty directories in the "D:\Projects Visual Studio\web\" path then how do you expect to get a positive result from the Test-Path cmdlet???

Also, understand the Get-ChildItem returns not just the file names in your shared directory, but also any sub-directories (although it won't look into those sub-directories unless you add the "-Recurse" switch). If you want only files then add the "-File" switch.

Does Test-Path test for sub-directories ?
Shall have a look tomorrow.

Hi @Gloops ,

Test-Path c:\Junk\*

Gives a false if empty.
Gives a true if a file or a folder is in Junk

At least, this explains well what UNC is.

Perhaps somebody knows if Powershell has a dedicated syntax to support it.
