While our bulk filename renamer is powerful and versatile, there are some limitations and system requirements you should be aware of for optimal performance.
All files are loaded into browser memory. Very large batches may slow down or crash the browser.
Cannot rename files outside the browser session. Original files remain unchanged on your system.
All files are processed as a flat list. Subfolder structures are not maintained in the output.
No save/load functionality. All work must be completed in a single browser session.
All file types supported for renaming, but preview only available for images.
Basic pattern matching only. No advanced regex features like lookaheads or backreferences.
Process very large file collections in multiple batches of 200-300 files each.
Close unnecessary browser tabs to free up memory for better performance.
Apply complex rules in separate steps rather than all at once in the action stack.
Download and clear the file list periodically when working with large batches.
Combine multiple actions for sophisticated renaming:
Result: "my file.jpg" ā "project_my_file_001.jpg"
Sort by date taken (EXIF) before numbering to create chronological sequences for photos.
Goal: vacation_001.jpg, vacation_002.jpg...
Goal: report_v2.1_final.docx, budget_Q3_2024.xlsx
Goal: Artist - Song Title.mp3
Solution: Check file size limits and browser compatibility. Try refreshing the page.
Solution: Sort or drag files into the desired order before applying numbering rules.
Solution: Use the "Remove symbols" or "Sanitize" options to clean filenames.
Solution: Check action stack order and ensure find/replace text matches exactly.
Solution: Check browser pop-up settings and ensure you have storage space.
Solution: Process files in smaller batches of 100-200 files for optimal performance.
