Modify my little PowerShell script

Hi guys,

I have the following code, works butter smooth. Copies a few files/folders from source to destination then applies ACL's. See that 3rd "copy-item" which gets a .nk2 and copies it over? Well in the source there are MULIPLE .nk2 files (with different names), how can I get it to scan that \outlook folder and copy the biggest (file size) .nk2 item and rename is outlookprofile.nk2?

gc folderlist.txt | % {
$user = "$_"
Import-Csv "C:\TEMP\Favorites\input.csv" | ForEach {
If ($_.FQDN -eq $env:USERDNSDOMAIN) { $file_server = $_.'Server IP' } 
$FavAcl = Get-Acl -path \\$file_server\profiles$\$user\Favorites\
$SigAcl = Get-Acl -path "\\$file_server\profiles$\$user\Application Data\Microsoft\Signatures\"

if (Test-Path -Path "\\$file_server\profiles$\$user\Favorites")
copy-item -path  \\$file_server\profiles$\$user\Favorites -destination \\$file_server\userhome$\$user\Favorites -recurse -force 
copy-item -path  "\\$file_server\profiles$\$user\Application Data\Microsoft\Signatures" -destination \\$file_server\userhome$\$user\AppData\Roaming\Microsoft\Signatures\ -recurse -force -ErrorAction SilentlyContinue
copy-item -path  "\\$file_server\profiles$\$user\Application Data\Microsoft\Outlook\outlook.nk2" -destination \\$file_server\userhome$\$user\AppData\Roaming\Microsoft\Outlook\outlook.nk2  -ErrorAction SilentlyContinue
Get-ChildItem -path \\$file_server\userhome$\$user\Favorites -Recurse -Force | Set-Acl -AclObject $FavAcl
Get-ChildItem -path \\$file_server\userhome$\$user\AppData -Recurse -Force | Set-Acl -AclObject $SigAcl
Get-Acl -path \\$file_server\profiles$\$user\Favorites\ | Set-ACL -path \\$file_server\userhome$\$user\Favorites\
Get-Acl -path  "\\$file_server\profiles$\$user\Application Data\Microsoft\Signatures\" | Set-Acl \\$file_server\userhome$\$user\AppData\
remove-item -path \\$file_server\profiles$\$user -recurse -force

Open in new window

I'll need it to keep the ACL from source to destination as well.
Thanks guys.

Just checked the manual and copy-item expect the path to exist if you copy a file.
If the source is a folder, it will create the path.

$bigNK2 = Get-ChildItem -path "\\$file_server\profiles$\$user\Application Data\Microsoft\Outlook" -Filter "*.nk2" | sort Length -Descending | select -First 1
if (!(Test-Path \\$file_server\userhome$\$user\AppData\Roaming\Microsoft\Outlook)) {
    New-Item \\$file_server\userhome$\$user\AppData\Roaming\Microsoft\Outlook -itemtype directory
copy-item -path  $bigNK2.FullName -destination \\$file_server\userhome$\$user\AppData\Roaming\Microsoft\Outlook\outlookprofile.nk2  -ErrorAction SilentlyContinue

Open in new window

Replace line 13 with these 2 lines:
$bigNK2 = Get-ChildItem -path "\\$file_server\profiles$\$user\Application Data\Microsoft\Outlook" -Filter "*.nk2" | sort Length -Descending | select -First 1
copy-item -path  $bigNK2.FullName -destination \\$file_server\userhome$\$user\AppData\Roaming\Microsoft\Outlook\outlookprofile.nk2  -ErrorAction SilentlyContinue

Open in new window

The first will get the largest nk2 file in that folder and the second will copy it as outlookprofile.nk2 in the destination folder.

Hi Dan,

I''m getting an error:
Copy-item : Could not find a part of the path '\\10.x.x.x\userhome$\username\AppData\Roaming\Microsoft\Outlook\outlookprofile.nk2'.
Should it not be creating that folder if it doesnt exist? Which it may exist or may not exist.. What is strange is the \Signature folder doesnt exists either in the destination yet that copies without an errors.

Yes, it should. If the script was running properly before, it should run the same now...

Can you add this between those 2 lines:
write-output $bigNK2.FullName

That's to see what is the name of the file being copied, maybe that's the problem.
levertmAuthor Commented:
Two things:

1) The name of the file is shown and it's correct, I verified both path and file name and it does pick up the biggest file size in the source folder.

2) if the destination folder \outlook exists your additions work, the biggest .NK2 file gets copied and renamed to outlookprofile.nk2 in the destination folder. If the destination folder \outlook does not it exists, your additions do not work.

Strange huh.. yet the signature folder copies over without any hiccups, even if it does not exist.

That did it Dan, thank you very much.
