Get Shared Folders & Access Permissions

I have compiled a command to dig out Shared folders & there access permissions.

=============================================================================================

ACL :

1.       Get-Acl c:\foldername | Select-Object Path,Owner,Group,AccessToString | Export-Csv -path C:\ACL.CSV

2.       Dir c:\foldername | Get-Acl | Select-Object Path,Owner,Group,AccessToString | Export-Csv -path c:\dir.csv

3.       Get-content -path c:\folders.txt | get-acl | Select-Object Path,Owner,Group,AccessToString | Export-Csv c:\folders.csv

4.       Get-Content Folders.txt | Foreach-Object { get-acl $_ }

5.       Classical Commands : Cacls & Xcacls

Share Folders :

1.       Get-WmiObject win32_share

2.       Get-WmiObject win32_share -filter "name='foldername'"

3.       Get-WmiObject win32_share | Select-Object path,name,description | Export-Csv c:\AllShareFolders.csv

4.       $Share = gwmi -class Win32_Share | sort type, name
$Share | ft name, description, type, path -auto 

Combined :

Get-WmiObject win32_share -filter "name='test'" | get-acl | Select-Object Path,Owner,AccessToString | fl

Whole & Soul:

Get-WmiObject win32_share | Get-Acl | Select-Object Path,Owner,AccessToString | Export-Csv -path c:\permissions.csv
