powershell list folders or files that are over 256 caharacters

You can check for file and folder name length limits in Windows using PowerShell. Here’s a script that can help you identify files and folders with names that exceed the 256 character limit in Windows:

powershell
Copy code
# Set the path to the root folder you want to check
$rootFolder = “C:\Path\To\Your\Folder”

# Function to recursively check file and folder names
function Check-PathLength {
param (
[Parameter(Mandatory = $true)]
[string]$path
)

# Check the length of the path
if ($path.Length -gt 256) {
Write-Host “Path length exceeds 256characters: $path”
}

# Check the length of subfolder names
$subfolders = Get-ChildItem -Directory $path
foreach ($subfolder in $subfolders) {
if ($subfolder.FullName.Length -gt 256) {
Write-Host “Subfolder name exceeds 256 characters: $($subfolder.FullName)”
}

# Recursively check subfolders
Check-PathLength -path $subfolder.FullName
}

# Check the length of file names
$files = Get-ChildItem -File $path
foreach ($file in $files) {
if ($file.FullName.Length -gt 256) {
Write-Host “File name exceeds 256 characters: $($file.FullName)”
}
}
}

# Start the checking process
Check-PathLength -path $rootFolder
Replace “C:\Path\To\Your\Folder” with the path to the root folder you want to check. This script will recursively check the length of file and folder names starting from the specified root folder and report any names that exceed the 256 character limit.
