PowerShell get folder security settings


How to check or get which accounts have the modify rights on a particular folder using PowerShell?

If the user account or security group account has modify rights, it means that account or group can delete the file or files on a folder.

To list the user accounts or security groups on a folder, a PowerShell scripts can come handy.

But of course it can be done via GUI, by right clicking on the folder and clicking on the security tab which will show the list of security accounts and its access settings.

The PowerShell code below will get the list of accounts which have modify rights on the folder specified on the script.

Here's the code:

$folder ="D:\myDFolder"
$acl = (Get-Acl $folder).Access   | where {$_.FileSystemRights -eq “Modify, Synchronize”} | select IdentityReference
Write-Output $acl

It's a three line code but does a very good job.

Sample output:
IdentityReference                                                                                                                                
-----------------                                                                                                                                
XDomain\maxUser
NT AUTHORITY\Authenticated Users

Output shows that maxUser and Authenticated Users have modify rights on "D:\myDFolder".


Cheers..Hope it helps..

Print error 016-799 - Fuji Film Xerox

016-799 Fuji Xerox or Fuji Film print error code. That shows a description error as “Print instruction Fail detected in decomposer.” The error code and error description are alien languages for users and even system administrators who are not familiar with Fuji Xerox error code. The error code is quite simple and easy to fix, if the job print goes to the printer but print out doesn’t come out. So, basically the print job was received by the printer, but the printer just doesn’t know what type of paper or what size to use or which tray to utilize for the print out. In some instances, this is just a paper mismatch but the error description; if using Windows 10 to print does not exactly points to what is the issue. First thing to check, is the paper size selected by the user to print. Example, if the printer configuration is A3 and A4 sizes only. But then the person printing the file accidentally chooses “A4 Cover” then this error 016-799 will occur. ...
