Copy Files

Copy Files

Creating copies of files and folders is a fundamental ability of the Windows file system. Using the available file and folder nodes, you can automatically copy files and folders and effortlessly perform tasks such as taking backups.

What Copy Files can do

• Seed sources (Core.Programming.Function) — resolves msg.fixtures_dir under $Home$/templates/.../fixtures, sets msg.files_to_copy to [source_a.txt, source_b.txt] and msg.default_dest to fixtures/dest.
• Input Dialog (Core.Dialog.InputBox) titled Copy files, message Select the folder to copy the file to.., default msg.default_dest → msg.destination_folder.
• Branch on cancel (Core.Programming.Function, outputs: 2) — if msg.destination_folder is empty, short-circuit to Core.Flow.Stop; otherwise proceed.
• Create destination (Core.FileSystem.Create, optType: directory, continueOnError: true) against msg.destination_folder, then Core.Flow.GoTo into Loop Start.
• Iterate (Core.Programming.ForEach) over msg.files_to_copy → msg.current_file, msg.current_index.
• Build destination (Core.Programming.Function) — extracts the basename of msg.current_file and sets msg.dest_path = msg.destination_folder + '\\' + basename.
• Copy (Core.FileSystem.Copy, continueOnError: true) from msg.current_file to msg.dest_path, then Core.Flow.GoTo back to Loop Start until the iterator exits and hits Core.Flow.Stop.

Behind the scenes

• continueOnError: true on Core.FileSystem.Create lets the flow proceed when the destination directory already exists, and on Core.FileSystem.Copy it keeps the loop running if a single file fails to copy.
• The loop is driven by a Core.Flow.Label + Core.Flow.GoTo pair wrapped around Core.Programming.ForEach so the per-file copy steps live on a separate wire and re-enter the iterator cleanly.
• Destination path is built by scanning for the last / or \\ so the flow works with fixtures written using either separator.
