function Copy-FilesWithRobocopy {
    <#
    .SYNOPSIS
    Copies files from a source directory to a destination directory using Robocopy and verifies the operation.
 
    .DESCRIPTION
    The Copy-FilesWithRobocopy function copies files from a source directory to a destination directory based on a specified file pattern using Robocopy. It validates the source and destination directories, checks disk space, logs the Robocopy process, and verifies the copy operation. It also handles locked files by finding and killing the locking processes.
 
    .PARAMETER Source
    The source directory from which files will be copied.
 
    .PARAMETER Destination
    The destination directory to which files will be copied.
 
    .PARAMETER FilePattern
    The file pattern to match files that should be copied. If not provided, defaults to '*'.
 
    .PARAMETER RetryCount
    The number of retries if a copy fails. Default is 2.
 
    .PARAMETER WaitTime
    The wait time between retries in seconds. Default is 5.
 
    .PARAMETER RequiredSpaceGB
    The required free space in gigabytes at the destination. Default is 10 GB.
 
    .PARAMETER Exclude
    The directories or files to exclude from the copy operation.
 
    .EXAMPLE
    Copy-FilesWithRobocopy -Source "C:\Source" -Destination "C:\Destination" -FilePattern "*.txt"
    Copies all .txt files from C:\Source to C:\Destination.
 
    .EXAMPLE
    "*.txt", "*.log" | Copy-FilesWithRobocopy -Source "C:\Source" -Destination "C:\Destination"
    Copies all .txt and .log files from C:\Source to C:\Destination using pipeline input for the file patterns.
 
    .EXAMPLE
    Copy-FilesWithRobocopy -Source "C:\Source" -Destination "C:\Destination" -Exclude ".git"
    Copies files from C:\Source to C:\Destination excluding the .git folder.

function Remove-EnhancedItem {
    <#
    .SYNOPSIS
    Removes a file or directory with enhanced logging and retry mechanisms.
 
    .DESCRIPTION
    This function attempts to remove the specified file or directory, with the option to forcefully kill processes that may be locking the file. It retries removal for a specified number of attempts if the file is locked, with a customizable delay between retries.
 
    .PARAMETER Path
    The full path of the file or directory to be removed.
 
    .PARAMETER ForceKillProcesses
    A switch that, when enabled, forces the termination of any processes that are locking the specified file or directory.
 
    .PARAMETER MaxRetries
    The maximum number of times the function will attempt to remove the item if it fails due to a locking process or other error. The default is 3 retries.
 
    .PARAMETER RetryInterval
    The number of seconds to wait between retries. The default is 5 seconds.
 
    .EXAMPLE
    Remove-EnhancedItem -Path "C:\temp\open.txt"
 
    Attempts to remove the file at C:\temp\open.txt, with the default retry mechanism if the file is locked.
 
    .EXAMPLE
    Remove-EnhancedItem -Path "C:\temp\open.txt" -ForceKillProcesses
 
    Attempts to remove the file at C:\temp\open.txt, forcefully terminating any locking processes if necessary.
 
    .EXAMPLE
    Remove-EnhancedItem -Path "C:\temp\open.txt" -MaxRetries 5 -RetryInterval 10
 
    Attempts to remove the file at C:\temp\open.txt, with a maximum of 5 retries and a 10-second wait between retries.

function Verify-CopyOperation {
    <#
    .SYNOPSIS
    Verifies that files have been correctly copied between a source and destination directory.
 
    .DESCRIPTION
    The Verify-CopyOperation function compares the contents of a source directory with a destination directory to ensure that all files and directories have been successfully copied.
    It reports missing files, extra files, and provides detailed information about any discrepancies found during the verification process.
 
    .PARAMETER SourcePath
    The path to the source directory whose contents are being copied and need verification.
 
    .PARAMETER DestinationPath
    The path to the destination directory where the files from the source have been copied.
 
    .EXAMPLE
    Verify-CopyOperation -SourcePath "C:\Source" -DestinationPath "C:\Destination"
    Verifies the copied contents between C:\Source and C:\Destination, checking for any discrepancies such as missing or extra files.
 
    .OUTPUTS
    Custom objects detailing missing, extra, or mismatched files between the source and destination.
 
    .NOTES
    The function uses recursion to verify subdirectories and outputs the results to the console.
    Any discrepancies between the source and destination directories are logged for analysis.
