Power shell script to list all files and folder permissions recursively

Question

Hi All,
I am looking for a powershell script to perform the following operations.
1) To list the folder and file permissions(Allow,Deny both) recursively in a given folder.
2) List out all the files and folders which are having the deny permission or having only the read access (or) only the write access. Basically the folder should have Read,Execute,Write permissions. Else we have to flag that file/folder name.
I had written a batch script for the same which does this task using icacls.exe output, but this script takes lot of time to recursively parse all the files ( ~1 lakh files).
Please help me with the powershell script for the same.
Thanks

Try this module: http://gallery.technet.microsoft.com/scriptcenter/PowerShellAccessControl-d3be7b83
After importing the module, you can run something like this:
dir c:\folder -recurse | Get-AccessControlEntry
That output can be exported to a CSV for later viewing. You can also provide some parameters to Get-AccessControlEntry to limit the results:
dir c:\folder -recurse | Get-AccessControlEntry -FileRights Write
dir c:\folder -recurse | Get-AccessControlEntry -AceType AccessDenied
dir c:\folder -recurse | Get-AccessControlEntry -AceType AccessAllowed -FileRights Write
