Referring to Gamaliel  s answer   args is an array of the arguments that are passed into a script at runtime - as such cannot be used the way Gamaliel is using it   This is actually working    myPath    C  whatever file    get actual Acl entry  myAcl   Get-Acl   myPath   myAclEntry    Domain User   FullControl   Allow   myAccessRule   New-Object System Security AccessControl FileSystemAccessRule  myAclEntry    prepare new Acl  myAcl SetAccessRule  myAccessRule   myAcl   Set-Acl   MyPath    check if added entry present Get-Acl   myPath    fl

Specifying inheritance in the FileSystemAccessRule   constructor fixes this  as demonstrated by the modified code below  notice the two new constuctor parameters inserted between  quot FullControl quot  and  quot Allow quot     Acl   Get-Acl  quot   R9N2WRN Share quot    Ar   New-Object System Security AccessControl FileSystemAccessRule  quot user quot    quot FullControl quot    quot ContainerInherit ObjectInherit quot    quot None quot    quot Allow quot     Acl SetAccessRule  Ar  Set-Acl  quot   R9N2WRN Share quot   Acl  According to this topic   quot when you create a FileSystemAccessRule the way you have  the InheritanceFlags property is set to None   In the GUI  this corresponds to an ACE with the Apply To box set to  quot This Folder Only quot   and that type of entry has to be viewed through the Advanced settings  quot   I have tested the modification and it works  but of course credit is due to the MVP posting the answer in that topic

In case you had to deal with a lot of subfolders contatining subfolders and other recursive stuff  Small improvment of  Mike L Angelo    mypath    path to folder   myacl   Get-Acl  mypath  myaclentry    username   FullControl   Allow   myaccessrule   New-Object System Security AccessControl FileSystemAccessRule  myaclentry   myacl SetAccessRule  myaccessrule  Get-ChildItem -Path   mypath  -Recurse -Force   Set-Acl -AclObject  myacl -Verbose   Verbosity is optional in the last line
