Recover multiple original files powershell due to onedrive sync issues - powershell

Question

We had a syncing issue that affected thousands of files.
A backup of the correct files was created in each folder by the sync tool. the backup has " -LocalPCName" added before the dot before the extension.
I am really a beginner in powershell.
I am trying to write a powershell script to go trough every folder and check if a file backup was create d for each file.
If a backup was created, I want to rename the file to add " -Wrongversion" and remove the " -LocalPCName" from the correct file.
This will basically recover the file to the correct version and make a copy of the wrong version.
I wrote this code but i am blocked at trying to match using -replace
Get-ChildItem *.* |
ForEach-Object {
If ($_.name -match "\s-LocalPCName")
{Get-ChildItem $_.Name -replace "\s-LocalPCName",""
}
}
Thank you for your help!
here is a newer version of my code but i get errors and i am concerned of using recurse, am i missing anything when this will go to subfolders? In this code, the LocalPCName is Didi2015
Get-ChildItem *.* -recurse|
ForEach-Object {
If ($_.name -match "\s-Didi2015")
{
$OldName = $_.Name -replace "\s-Didi2015",""
$dir=$_.DirectoryName
$ext = $_.Extension
$file = $OldName.Substring(0, $OldName.LastIndexOf('.'))
Write-Output $dir
Write-Output $ext
Write-Output $file
$Newname = $file + " -Wrongversion" + $ext
Write-Output $Newname
Rename-Item -Path $OldName -NewName $Newname -WhatIf
Rename-Item -Path $_ -NewName $OldName -WhatIf
}
}

Answer 1

Here is my final code. it works.
dir *-Didi2015*.* -Recurse|
ForEach-Object {
If ($_.name -match "-Didi2015")
{
$OldName = $_ -replace "-Didi2015",""
$dir=$_.DirectoryName
$ext = $_.Extension
$file = $OldName.Substring(0, $OldName.LastIndexOf('.'))
# Write-Output $dir
# Write-Output $ext
# Write-Output $file
# Write-Output $OldName
# Write-Output $Newname
# Write-Output $_.Name
$Newname = $file + "-Wrongversion" + $ext
Rename-Item -Path $OldName -NewName $Newname -WhatIf
Rename-Item -Path $OldName -NewName $Newname -Force
Rename-Item -Path $_ -NewName $OldName -WhatIf
Rename-Item -Path $_ -NewName $OldName -Force
}
}
