PowerShell Rename-Item on Long Named Files Warning Removal

Question

I try to rename files with PwerShell Rename-Item cmdlet. Code below

Get-ChildItem -recurse * `
  | ?{!$_.PsIsContainer} `
  | Rename-Item -NewName {$_.FullName -Replace '[email protected]','.abcd@email_A.com.abcd@email_B.com.abcd@email_E.com'}

But, PowerShel tells me about long path or file name; which is irrelevant to my process. But it is strongly necessary keep new long name.

How to except this error?

Answer 1

is it possible ask you about code example? The following commented code snippet (conservative approach) could help:

Get-ChildItem -recurse * | Where-Object {!$_.PsIsContainer} | 
  ForEach-Object {
    ###  in regular expression:  ↓           ↓   escape dots
    $NewName = $_.Name -Replace '\.abcd@email\.com',
      '.abcd@email_A.com.abcd@email_B.com.abcd@email_E.com'

    ### here is right place to check target filename length:
    $targetLength = 1 + $_.DirectoryName.Length + $NewName.Length

    Rename-Item -Path $_.FullName -NewName $NewName
  }
