For those who may not know: You can get high-quality SVG icons for your visual documentation straight from Microsoft (just be sure to read the terms). The link is here: https://learn.microsoft.com/en-us/azure/architecture/icons/#icon-terms

Once you download them, you can use a simple script to put them all in a single folder and clean up the file name. (I lost the one I wrote before, here's one from AI that worked for me today. It's overcomplicated but it works.). Just replace <FOLDERHERE> with where you extracted the downloaded folder.

# Set the root folder
$rootFolder = '<FOLDERHERE>'

# Get all .svg files in the root folder and its subfolders
$files = Get-ChildItem -Path $rootFolder -Filter *.svg -Recurse -File

# Loop through each file
foreach ($file in $files) {
    # Ensure the file is not already in the root folder
    if ($file.DirectoryName -ne $rootFolder) {
        # Extract the filename and remove the first 19 characters
        $newFileName = $file.Name.Substring(19)

        # Ensure the new filename is valid (avoid empty names)
        if ($newFileName -ne "") {
            # Set the destination path
            $destinationPath = Join-Path -Path $rootFolder -ChildPath $newFileName

            # Handle duplicate filenames by appending a number if necessary
            $counter = 1
            while (Test-Path $destinationPath) {
                $nameWithoutExt = [System.IO.Path]::GetFileNameWithoutExtension($newFileName)
                $extension = [System.IO.Path]::GetExtension($newFileName)
                $newFileName = "{0}_{1}{2}" -f $nameWithoutExt, $counter, $extension
                $destinationPath = Join-Path -Path $rootFolder -ChildPath $newFileName
                $counter++
            }

            # Move the file to the root folder with the new name
            Move-Item -Path $file.FullName -Destination $destinationPath
        } else {
            Write-Host "Skipping file $($file.FullName) because the new filename is empty after removing characters."
        }
    }
}

If you're on windows, SVGs won't load with thumbnails without something like powertoys (which you should have installed anyway, IMHO). https://github.com/microsoft/PowerToys

In conjunction with draw.io or the program of your chosing, this really levels up your documentation.
