A simple PowerShell script I made for fun/learning, that automates image collection from folders which contain potentially any file type. The collected images are then stored together in a separated folder

img_collector.ps1

# --- PURPOSE ---
# This script picks all and only the .png/.jpg/.jpeg images from all the first level sub-folders
# of a determined source folder ($src_folder_name), and it then copies them inside
# another dedicated destination folder ($dest_folder_name).
# The script does not overwrite image files as, before each copying attempt,
# it preemptively checks for the existence of a file with the same name in the destination folder.

# --- INSTRUCTIONS ---
# - Option 1 -
# Launch PowerShell and move to the folder where this script has been stored, then run the script with:
# .\img_collector.ps1
# - Option 2 -
# Alternatively, launch File Explorer, reach the folder where this script has been stored, then right-click on this file,
# and finally left-click on the "Run with PowerShell" overlaying menu entry.

# --- PARAMETERS ---
$src_folder_name = "Original folders"  # Name of the source folder
$dest_folder_name = "Filtered images"  # Name of the destination folder



# --- CODE ---
$src = $PSScriptRoot + "\$src_folder_name"
$dest = $PSScriptRoot + "\$dest_folder_name"
# The 2 instructions above generate absolute paths to the source and destination folders.
# This way, the script is independent from the location it gets stored in.
# The only requirement is that this script, the source folder and the destination folder
# are located under the same parent folder (represented by "." below):
# .
# ├── img_collector.ps1
# ├── $src_folder_name
# │   ├── sub-folder 1
# │   ├── sub-folder 2
# │   ├── sub-folder 3
# │   └── etc.
# └── $dest_folder_name

$img_counter = 0  # Counter for the number of successfully copied images
$file_total = 0  # Counter for the total number of parsed files
$subfolder_total = 0  # Counter for the number of parsed source sub-folders

ForEach ($dir in (Get-Item -Path "$src\*" | ?{$_.PSIsContainer}))  # N.B.: $dir and $file represent paths!
{

	ForEach ($file in (Get-Item -Path "$dir\*"))
	{

		#Write-Output $file  # Useful for debugging

		$file_name = Split-Path $file -leaf

		If ($file -Like "*.png" -Or $file -Like "*.jpg" -Or $file -Like "*.jpeg" -And -Not(Test-Path -Path .\$dest_folder_name\$file_name))
		{
			Copy-Item $file -Destination $dest
            		$img_counter++
		}

        	$file_total++
	}

    	$subfolder_total++
}

Write-Output "`nNew images copied : `t$img_counter`nTotal files parsed: `t$file_total`nSub-folders parsed: `t$subfolder_total`n"
