copy files from folder and then delete some files with an exception - powershell

Question

I have folder called Logfolder in C.
C:\LogFolder
it has multiple logs with name as follows
errorLogs.log
errorLogs.log.1
errorLogs.log.2
errorLogs.log.3
Transmitlogs.log
Transmitlogs.log.1
Transmitlogs.log.2
Transmitlogs.log.3
Transmitlogs.log.4
Transmitlogs.log.5
Receivelogs.log
Receivelogs.log.1
Receivelogs.log.2
Receivelogs.log.3
Receivelogs.log.4
Dataexchange.log
Dataexchange.log.1
and many other with the different name but with same extension like .log, .log.1 and so on.
I am interested in only above mention logs.
my goal is to copy this logs starting from log.1 upto log.10 or 20 all which exist and than
delete the original file with an exception .log and .log.1.
I have achieved following until now.
$logLocation = "C:LogFolder"
$tempLocation = "C:\Temp\Logs\"
$LogfileName = "errorLogs.log.", "Transmitlogs.log.","Receivelogs.log.","Dataexchange.log."
foreach ($element in $LogfileName)
{
$NewLogFileName = -join($element,"*")
Copy-Item -Path "$logLocation\$NewLogFileName" -Destination $tempLocation
}
I am able to copy all logs starting from .log.1 and all other which exist.
my problem is how can i delete those logs from original folder without deleting .log and .log.1
I have tried the following but not working.
foreach ($element in $LogfileName)
{
$deleteLogFileName = -join($element,"*")
Remove-Item –path "$logLocation\$deleteLogFileName" -exclude *.log, *.log.1
}

You can do that by selectively copy only file *.log.1 to the destination folder and move the others. That would save you removing files from the source location afterwards.
The thing that matters here most is to get a list of files that
have a numeric extension
have a basename like 'errorLogs.log', 'Transmitlogs.log', 'Receivelogs.log' or 'Dataexchange.log'
Try
$logLocation = "C:\LogFolder"
$tempLocation = "C:\Temp\Logs"
# if the destination folder does not exist yet, creatre it first
if (!(Test-Path -Path $tempLocation -PathType Container)) {
$null = New-Item -Path $tempLocation -ItemType Directory
}
# get an array of objects of the files where the extension ends in a numeric value
# and where the basename is either 'errorLogs.log', 'Transmitlogs.log', 'Receivelogs.log'
# or 'Dataexchange.log'.
$files = Get-ChildItem -Path $logLocation -Filter '*.log*' -File |
Where-Object {$_.Name -match '^(errorLogs|Transmitlogs|Receivelogs|Dataexchange)\.log\.\d+$' } |
Select-Object FullName, #{Name = 'Number'; Expression = {[int]($_.Name.Split(".")[-1])}}
foreach ($file in $files ) {
if ($file.Number -eq 1) {
# this file should be copied
Copy-Item -Path $file.FullName -Destination $tempLocation -Force
}
else {
# the others are to be moved
Move-Item -Path $file.FullName -Destination $tempLocation -Force
}
}
