#Functions
#2)	Functions

#Create a function named CheckFolder that checks for the existence of a specific directory/folder that is passed 
#to it as a parameter. Also, include a switch parameter named create. If the directory/folder does not exist and 
#the create switch is specified, a new folder should be created using the name of the folder/directory that was 
#passed to the function.

function Check-Folder() {
    param([string]$folder, [switch]$create)

    $exists = Test-Path $folder

    if(!$exists) {
        Write-Host "The folder $folder doesn't exist"
    } else {
        Write-Host "Folder $folder exists!"
    }
    if(!$exists -and $create) {
        mkdir $folder
        Write-Host "Folder $folder created!"
    }
}


#Create a function named DisplayFolderStatistics to display folder statistics for a directory/path that is passed 
#to it. Output should include the name of the folder, number of files in the folder, and total size of all files in 
#that directory.

function DisplayFolderStadistics($folder) {
    $folder_name = Get-ItemProperty $folder
    $items_size = ls $folder -Recurse | Measure-Object -Property Length -Sum
    $values = "" | Select Name, Count, Size

    $values.Name = $folder_name.Name
    $values.Count = $items_size.Count
    $values.Size = [math]::round($items_size.Sum/1MB, 2)

#3)	Main processing

#a) Test for existence of the source folder (using the CheckFolder function).
Check-Folder $source

#b) Test for the existence of the destination folder; create it if it is not found (using the CheckFolder function 
#with the –create switch).Write-Host "Testing Destination Directory - $destination"
Check-Folder $destination -create


#c) Copy each file to the appropriate destination.
#get all the files that need to be copied
Copy-Item -Path ($source + "\*") -Destination $destination -Recurse


#c-i) Display a message when copying a file. The message should list where the file is being
#moved from and where it is being moved to.

Write-Host "Copying files from $source to $destination"



#d) Display each target folder name with the file count and byte count for each folder.
