Powershell getfiles.count() to exclude thumbs.db - powershell

Question

We have a script running daily that removes old files and directories from an area that people use to transfer data around. Everything works great except for one little section. I want to delete a folder if it's older than 7 days and it's empty. The script always shows 1 file in the folder because of the thumbs.db file. I guess I could check to see if the one file is thumb.db and if so just delete the folder but I'm sure there is a better way.
$location = Get-ChildItem \\dropzone -exclude thumbs.db
foreach ($item in $location) {
other stuff here going deeper into the tree...
if(($item.GetFiles().Count -eq 0) -and ($item.GetDirectories().Count -eq 0)) {
This is where I delete the folder but because the folder always has
the Thumbs.db system file we never get here
}
}

Answer 1

$NumberOfFiles = (gci -Force $dir | ?{$_ -notmatch "thumbs.db"}).count

You can try the get-childitem -exclude option where all files/items in your directory will be
counted except those that end in db:
$location = get-childitem -exclude *.db
It also works out if you specify the file to exclude, in this case thumbs.db
$location = get-childitem -exclude thumb.db
Let me know if this works out.
Ah, I also just noticed something,
$location = get-childitem -exclude *.db
Will only handle .db items in the location directory, if you're going deeper into the tree (say from your GetFiles() and GetDirectories() methods) then you may still find a thumb.db. Hence you'll have to add the exclude option in these methods to ignore thumbs.db.
So, for example in your $item.getFiles() method, if you use get-childitem you will have to specify the -exclude option as well.
Sorry, I should have read your question more closely.

Use this method to provide a exclusion list in the form of a simple text file to exclude specific files or extensions from your count:
$dir = 'C:\YourDirectory'
#Type one filename.ext or *.ext per line in this txt file
$exclude = Get-Content "C:\Somefolder\exclude.txt"
$count = (dir $dir -Exclude $exclude).count
$count
