Permission errors in PowerShell -

i new powershell. when trying write simple script deletes contents of folder , fills files copied different folder, permissiondenied error.

details:

+ remove-item <<<<  d:\path\* -recurse     + categoryinfo : permissiondenied: (save.gif:fileinfo) [remove-item], ioexception     + fullyqualifiederrorid : removefilesystemitemunauthorizedaccess,microsoft.powershell.commands.removeitemcommand 

where problem? able manipulate both folders through explorer. error occurs both when running script file , shell (using windows powershell ise). ise process runs under account. i'm running windows 7 professional , local administrator.

edit: after richard's suggestion, tried verbose mode (which seemed have no effect).

ps z:\> $error[0] | fl * -force  psmessagedetails      :  exception             : system.io.ioexception: not enough permission perform operation. targetobject          : d:\path\file.txt categoryinfo          : permissiondenied: (d:\path\file.txt:fileinfo) [remove-item], ioexception fullyqualifiederrorid : removefilesystemitemunauthorizedaccess,microsoft.powershell.commands.removeitemcommand errordetails          : cannot remove item d:\path\file.txt: not enough permission perform operation. invocationinfo        : system.management.automation.invocationinfo pipelineiterationinfo : {0, 1} 

i don't see of use there (but tips anyway).

edit 2: okay, here's script source:

remove-item d:\path_a\* -recurse copy-item d:\path_b\* d:\path_a\ 

that's it. remove-item seems throw @ every file.

is uac enabled? if try running powershell session 'administrator'. looks don't have permission delete objects.

we have restrictive security policies work , users not familiar uac burned time.
