BigFileFinder-Python

A GUI application for scanning folders and drives to find and manage large files. Built with Python and Tkinter.

Features

  • Recursive Folder Scanning: Scan entire directories and drives to find all files
  • Size-Based Sorting: Files are automatically sorted by size (largest first)
  • Real-Time Progress: Live updates showing scan progress and file count
  • File Selection: Select individual files or all files at once
  • Safe Deletion: Delete selected files with confirmation dialog
  • Size Statistics: View total size of selected files and freed space
  • Error Handling: Gracefully handles permission errors and inaccessible files

Requirements

  • Python 3.x
  • Tkinter (usually included with Python)

Installation

No installation required! Just run the script:

python BigFileFinder.py

Or make it executable on Unix-like systems:

chmod +x BigFileFinder.py
./BigFileFinder.py

Usage

  1. Browse: Click "Browse..." to select a folder or drive to scan
  2. Start Scan: Click "Start Scan" to begin scanning for files
  3. Stop: Click "Stop" at any time to halt the scan (results so far will be displayed)
  4. Select Files: Click on files to select them, or use "Select All"
  5. Delete: Click "Delete Selected Files" to remove unwanted files (confirmation required)

Interface

The application displays:

  • Size (bytes): Exact file size in bytes
  • Size (MB): File size in megabytes for easier reading
  • File Path: Full path to the file

Selected files show their total count and combined size at the bottom.

Performance

  • Scans are performed in a background thread to keep the UI responsive
  • Files are periodically sorted during scanning for efficient memory usage
  • Handles large directories with thousands of files

Safety Features

  • Confirmation Dialog: Deletion requires explicit confirmation
  • Detailed Error Reporting: Shows which files failed to delete and why
  • Read-Only Protection: Cannot delete files the user doesn't have permission to access

File Size Formatting

Sizes are automatically formatted in human-readable units:

  • B (Bytes)
  • KB (Kilobytes)
  • MB (Megabytes)
  • GB (Gigabytes)
  • TB (Terabytes)
  • PB (Petabytes)

License

Free to use and modify.

Notes

  • Scanning system drives may take considerable time
  • Always verify files before deletion - this action cannot be undone
  • Some system files may be inaccessible due to permission restrictions
