How to get folder name thats different on all user profiles - powershell

Question

I like to know how to get 5J91Q4CX.C10 to use in a variable.
C:\Users\user\AppData\Local\Apps\2.0\5J91Q4CX.C10
On all user profiles this folder has a different name.
It is always 8 numbers and digits then a . and then 3 digits or numbers.
I need to use this for a powershell script.
Any idea how I can make a variable for this foldername?
Thanks

Answer 1

I'd do something like this:
#Loop through all user profile folders using something like this:
$userFolders = Get-ChildItem -Path "C:\Users\" -Directory -Force -ErrorAction SilentlyContinue |
Where-Object { #('All Users','Default User', 'Public', 'Default') -notcontains $_.Name } |
Select-Object -ExpandProperty Name
# next loop through these folders to find the foldername that can be different for each user
foreach ($userName in $userFolders) {
$folderName = Get-ChildItem -Path "C:\Users\$userName\AppData\Local\Apps\2.0" -Directory -Force -ErrorAction SilentlyContinue |
Where-Object { $_.Name -match '[A-Za-z0-9]{8}\.[A-Za-z0-9]{3}' } |
Select-Object -ExpandProperty Name
# do something with this variable
Write-Host "C:\Users\$userName\AppData\Local\Apps\2.0\$folderName"
}

Some RegEx could do the trick:
$str = "C:\Users\user\AppData\Local\Apps\2.0\5J91Q4CX.C10"
$str -match '.*\\(.*)$'
$matches[1] # 5J91Q4CX.C10
.*\\(.*)$ matches all chars after the last dash \ and before the end of the line $

not sure what you are really trying to do... you could do a directory search through the C:\Users to report back on all subfolders and then a Foreach loop to go through each subfolder and create the file wanted in the destination etc, something like:
$FOLDERS = Get-ChildItem C:\Users -Directory
FOREACH ($FOLDER in $FOLDERS) {
#WHATEVER YOU WANT TO DO
}
