Directory list recursive parent and child within-CodePudding

I would like to get a directory listing with -recurse but to show the sub directories right under the parent. Here is what I tried:

Get-ChildItem -Directory -Depth 3 | Select-Object Fullname

The results show first top-level directories and only then level 2 and only then level 3

Example:

C:\Users\Moshe\onedrive\pictures\35mm_Film (has no sub directories)
C:\Users\Moshe\onedrive\pictures\Camera imports
C:\Users\Moshe\onedrive\pictures\Camera Roll

and only then

C:\Users\Moshe\onedrive\pictures\Camera imports\Folder1
C:\Users\Moshe\onedrive\pictures\Camera imports\Folder2
C:\Users\Moshe\onedrive\pictures\Camera imports\Folder3

and then

C:\Users\Moshe\onedrive\pictures\Camera Roll\2014
C:\Users\Moshe\onedrive\pictures\Camera Roll\2016

I would like to get the list showing parent and right underneath its sub dir For example:

C:\Users\Moshe\onedrive\pictures\35mm_Film (has no sub directories)
C:\Users\Moshe\onedrive\pictures\Camera imports

C:\Users\Moshe\onedrive\pictures\Camera imports\Folder1
C:\Users\Moshe\onedrive\pictures\Camera imports\Folder2
C:\Users\Moshe\onedrive\pictures\Camera imports\Folder3
C:\Users\Moshe\onedrive\pictures\Camera Roll

C:\Users\Moshe\onedrive\pictures\Camera Roll\2014
C:\Users\Moshe\onedrive\pictures\Camera Roll\2016

it will also be nice to have the count of files for each directory but not crucial

For example:

C:\Users\Moshe\onedrive\pictures\35mm_Film 100
C:\Users\Moshe\onedrive\pictures\Camera imports 0 (no files in the parent) C:\Users\Moshe\onedrive\pictures\Camera imports\Folder1 20
etc

Thanks

To get the directories in that order you can use Sort-Object.

Example:

Get-ChildItem -Directory -recurse -Depth 3 | Select-Object Fullname | Sort-Object Fullname

This will give you the parent and their subfolders in order.

CodePudding user response：

If you want to do this without the need of sorting afterwards the solution can be a bit cumbersome, you can either use a recursive function / script block or as shown in this example, with a Stack<T> and as optional you can use a class:

class Tree {
    [int64] $Depth
    [string] $Path
    [int] $FileCount
    hidden [IO.DirectoryInfo] $Instance

    Tree ([IO.DirectoryInfo] $Directory, [int] $Depth) {
        $this.Instance = $Directory
        $this.Path     = $Directory.FullName
        $this.Depth    = $Depth
        $this.CountFiles()
    }

    [IO.DirectoryInfo[]] EnumerateDirectories() {
        return $this.Instance.EnumerateDirectories()
    }

    [void] CountFiles() {
        $this.FileCount = $this.Instance.GetFiles().Count
    }
}


$stack = [Collections.Generic.Stack[Tree]]::new()
$maxDepth = 3
# initial path here
$path = 'C:\Users\Moshe\onedrive\pictures'
$stack.Push([Tree]::new($path, 0))

while($stack.Count) {
    $folder = $stack.Pop()
    if($folder.Depth -gt $maxDepth) {
        continue
    }

    # this condition is to skip hidden and system folders,
    # remove it if you want to show all
    if(-not ($folder.Instance.Attributes -band [IO.FileAttributes]'Hidden, System')) {
        $folder
    }

    foreach($i in $folder.EnumerateDirectories()) {
        $stack.Push([Tree]::new($i, $folder.Depth   1))
    }
}
