showing the total of folders/files in drive root

Properties are shown differently for folders and roots.
Root properties only shows used and free space.
Folder properties shows Size, Size on Disk, number of files/folders.
Questions:
1 - How can I discover on the root drive the total of folders and files on drive?
2 - Better, how could I list the number of files within each folder?
3 - Even better, how could I list the total of subfolders and files at each level within the tree branches?

You would be asking for a drive graphing program. There are numerous. I'm not completely certain of what you mean, but I believe it would come under one of two programs.

WinDirStat is most peoples first port of call. TreeSize Free will show you the total number of files. I believe the latter has a 30 day trial of it's premium software that would be able to save all kinds of data about your drive to a file.

WinDirStat - Windows Directory Statistics
TreeSize Free - Quickly Scan Directory Sizes and Find Space Hogs
Hope this helps.

I'd go for TreeSize Free as well - it shows number of files and sizes for all/any directory or sub-directory you choose. If you wanted though you could do it using the PowerShell Get-ChildItem command

1 - How can I discover on the root drive the total of folders and files on drive?
2 - Better, how could I list the number of files within each folder?

These are pretty much the same - just change the drive and say if you want files or directories...

Code:

(Get-ChildItem "C:" -Recurse -Directory| Measure-Object | %{$_.Count}) | format-table  (Get-ChildItem "C:" -Recurse -File| Measure-Object | %{$_.Count}) | format-table

3 - Even better, how could I list the total of subfolders and files at each level within the tree branches?

You could combine the 2 above and make a little loop... Note that if you look at the root of C: there are 20000+ sub-directories so it might be a little useless as information (too much of it) although you could output it to excel I suppose..

Anyway if you narrow the starting directory it might be useful.

Code:

$StartDir = Get-ChildItem "D:Drivers" -Directory -Recurse | Select -Expandproperty FullName    Function New-ReportLine ($Directory,$SubDirectories,$Files)  {      New-Object -TypeName psObject -Property @{Directory=$Directory; SubDirectories=$SubDirectories; Files=$Files}  }    $report = $StartDir | ForEach-Object {      $SubDirectories = (Get-ChildItem -Directory -Path $_ | Measure-Object | %{$_.Count})      $Files = (Get-ChildItem -File -Path $_ | Measure-Object | %{$_.Count})      New-ReportLine -Directory $_ -SubDirectories $SubDirectories -Files $Files  }    $report | Format-Table Directory,SubDirectories,Files –AutoSize

Gives an output like

Code:

PS C:Windowssystem32> C:UsersHaliDesktopUntitled1.ps1    Directory                                  SubDirectories Files  ---                                  ------ ---  D:DriversDisk                                         0     0  D:DriversNetwork                                      2     0  D:DriversUSB                                          0     0  D:DriversNetworkVEN_14E4_DEV_16A3                    1     4  D:DriversNetworkVEN_14E4_DEV_4331                    0     9  D:DriversNetworkVEN_14E4_DEV_16A3amd64              0     1
