Error while running powershell script - powershell

Question

I want to remove bak files after zip from all subfolder for given path, so all duplicate files with extension .bak will be removed,i run below script but getting error.
$filePath = "d:\Test\"
$Afiles = Get-ChildItem -Recurse -Path $filePath | Where-Object {$_.Extension -eq ".bak"}
$Bfiles = Get-ChildItem -Recurse -Path $filePath | Where-Object {$_.Extension -eq ".7z"}
$Alist = #()
$Blist = #()
foreach( $A in $Afiles) {
$Alist += $A.baseName
}
foreach( $B in $Bfiles) {
$Blist += $B.baseName
}
foreach($A in $Alist) {
if($Blist -contains $a)
{
rm ("$A.bak")
}
}
I am receiving below error :
Remove-Item : Cannot find path 'C:\Users\******\Desktop\master_backup_2015_08_21_013722_8370267.bak' because it does not exist.

Answer 1

You're receiving error because you're not specifying full path for rm command and PowerShell tries to delete file in your current directory.
Try this:
$Path = 'D:\Test'
Get-ChildItem -Path $Path -Recurse -Filter '*.7z' | ForEach-Object {
$BackupFile = Join-Path -Path (Split-Path $_.FullName -Parent) -ChildPath ($_.BaseName + '.bak')
if(Test-Path -Path $BackupFile){
Remove-Item -Path $BackupFile
}
}
