Delete Files of Specific Size Range

Overview

Scans a directory and deletes files whose size falls inside a min/max range. Useful for pruning oversized logs or clearing tiny scratch files.

Delete Files of Specific Size Range

Managing considerable amounts of files can be inefficient when performed by manual labor. Robomotion enables you to filter and handle files and manage your machine's storage automatically.

What Delete Files of Specific Size Range can do

  • Seed fixtures (Core.Programming.Function + three Core.FileSystem.WriteFile) — drops small.txt (200 B), medium.txt (3 KB) and large.txt (20 KB) under msg.fixtures_dir so the template is runnable out of the box.
  • Input Dialog (Core.Dialog.InputBox) titled Delete files by size range, prompt What is the minimum size of the files you want to delete? (in KB), default 1 → msg.min_size_text.
  • Input Dialog (Core.Dialog.InputBox) with prompt What is the maximum size of the files you want to delete? (in KB), default 10 → msg.max_size_text.
  • Input Dialog (Core.Dialog.InputBox) with prompt Please select the folder to delete files from...., default msg.fixtures_dir → msg.selected_folder.
  • Parse inputs (Core.Programming.Function, outputs: 2) — coerces to msg.minimum_size / msg.maximum_size; missing folder or NaN short-circuits to Core.Flow.Stop.
  • List directory (Core.FileSystem.List, optAbsolutePath: true, optSize: true, optIsDir: true) on msg.selected_folder → msg.all_files_in_folder.
  • Loop (Core.Flow.Label + Core.Programming.ForEach over msg.all_files_in_folder → msg.current_file):
    • Size range check (Core.Programming.Function, outputs: 2) — skips directories; keeps entries where Size / 1024 is within [minimum_size, maximum_size].
    • In-range files: set msg.file_to_delete = msg.current_file.Name, then Core.FileSystem.Delete (continueOnError: true), then Core.Flow.GoTo the loop label.
    • Out-of-range files: Core.Flow.GoTo the loop label directly.
  • When the ForEach exhausts the list it falls through to Core.Flow.Stop.

Behind the scenes

  • Size comparisons convert bytes to KB (Size / 1024) and are inclusive on both bounds — a 1024 B file with minimum_size = 1 passes.
  • Directory entries are filtered out before the size check so nested folders aren't considered for deletion.
  • Deletion is unconditional (no recycle bin, no confirmation) and uses continueOnError so one locked file doesn't abort the loop.
