I'll help you create a Python script to find and manage duplicate files in a directory. This tool will identify files with identical content and provide options to delete or keep one copy.

Let me create a Python script with a simple command-line interface:


*Edited relevant file*

### Planner Response

I've created a Python script called [duplicate_finder.py](cci:7://file:///c:/Users/rsrivaishnavi/CascadeProjects/windsurf-project-2/duplicate_finder.py:0:0-0:0) that helps you find and manage duplicate files. Here's what it does:

### Features:
- Scans a directory and its subdirectories for duplicate files
- Identifies duplicates by both file size and content hash
- Shows detailed information about found duplicates
- Provides an option to automatically delete duplicates (keeping one copy)
- Displays the total space that can be recovered

### How to use:

1. **Basic usage** (just find duplicates):
```bash
python duplicate_finder.py "path/to/your/directory"

2. Find and delete duplicates (keeping one copy of each):

python duplicate_finder.py "path/to/your/directory" --delete

Example output:

Scanning for duplicate files in: C:\path\to\your\directory

Found 3 groups of duplicate files (5 duplicates in total):

Group 1 - 2.50 MB each:
  1. folder1\image1.jpg
  2. folder2\image_copy.jpg
  3. backup\image1(1).jpg

Group 2 - 150.00 KB each:
  1. docs\report.pdf
  2. archive\report.pdf

Group 3 - 5.00 MB each:
  1. videos\clip.mp4
  2. temp\clip.mp4

Total space wasted by duplicates: 12.80 MB

Notes:

• The script skips files it can't access
• It shows file sizes in a human-readable format
• When using --delete, it keeps the first file in each group and removes the duplicates
• The script is safe to run in read-only mode (without --delete)

Would you like me to run it on a specific directory for you?

Planner Response

I see you're looking for a tool to find and manage files with duplicate names rather than duplicate content. Let me create a script that focuses on filename duplicates instead.

Edited relevant file

Planner Response

I've created a new script called filename_duplicate_finder.py that specifically finds and manages files with duplicate names (rather than duplicate content).

Features:

• Scans a directory and its subdirectories for files with the same name
• Shows detailed information about found filename duplicates
• Provides options to rename duplicate files automatically or interactively
• Displays file sizes for comparison

How to use:

1. Basic usage (just find duplicate filenames):

python filename_duplicate_finder.py "path/to/your/directory"

2. Auto-rename duplicates (adds index suffix to duplicates):

python filename_duplicate_finder.py "path/to/your/directory" --rename

3. Interactive rename (choose which files to rename):

python filename_duplicate_finder.py "path/to/your/directory" --rename --interactive

Example output:

Scanning for files with duplicate names in: C:\path\to\your\directory

Found 2 duplicate filenames (3 duplicates in total):

Duplicate #1: 'report.pdf'
  1. docs\report.pdf (150.00 KB)
  2. archive\report.pdf (150.00 KB)
  3. old\report.pdf (120.00 KB)

Duplicate #2: 'config.json'
  1. settings\config.json (2.50 KB)
  2. backup\config.json (2.30 KB)

Renaming behavior:

• With --rename: Automatically renames all duplicates except the first one in each group

  • Example: report.pdf → report_1.pdf, report_2.pdf

• With --rename --interactive: Gives you options for each group of duplicates:

  • Rename all except first
  • Select specific files to rename
  • Skip renaming for this group

Would you like me to make any adjustments to this script or would you like to see it in action on a specific directory?

User Input

filename must be renamed but not at the end, the file will have a pattern like .dd__text. - the dd must be incremented by 1. also, the filename should be checked across a directory having many folders. after the renaming, the directory should be again checked for duplicates. this process should repeat until there is no filename duplicates found in the directory. Also provide a detailed log step by step -of the duplicate filenames found and renamed filenames

Planner Response

I understand you need a more specific filename renaming pattern. You want to:

1. Find duplicate filenames across a directory with many subfolders
2. Rename files with a pattern like .*dd__text.* where dd is a number that should be incremented
3. Repeat the process until no duplicates remain
4. Generate a detailed log of all changes

Let me create a new script that implements this logic:

Edited relevant file

Planner Response

I've created a new script called pattern_filename_renamer.py that implements your specific requirements for finding and renaming duplicate filenames with a pattern-based approach.

Features:

• Finds duplicate filenames across a directory and all its subfolders
• Specifically handles filenames with the pattern .*dd__text.* where dd is a two-digit number
• Increments the number (dd) by 1 when renaming files
• Repeats the process until no duplicates remain
• Creates a detailed log file with step-by-step information
• Handles cases where the incremented filename already exists

How to use:

python pattern_filename_renamer.py "path/to/your/directory"

You can also specify a maximum number of iterations:

python pattern_filename_renamer.py "path/to/your/directory" --max-iterations 20

How it works:

1. Pattern Recognition: The script looks for filenames with the pattern .*dd__text.* where:

   • .* is any prefix
   • dd is a two-digit number (like 01, 02, etc.)
   • __text is any text with double underscores
   • .* is any suffix including file extension

2. Renaming Logic:

   • For files matching the pattern: Increments the number by 1
   • For files not matching the pattern: Adds "_01" before the extension

3. Iteration Process:

   • Scans the directory for duplicate filenames
   • Renames all duplicates (keeping the first occurrence unchanged)
   • Repeats until no duplicates are found or max iterations reached

4. Logging:

   • Creates a timestamped log file (e.g., rename_log_20251104_202500.txt)
   • Logs each iteration, duplicate found, and renaming action
   • Shows summary statistics at the end

Example log output:

2025-11-04 20:25:00 - INFO - Starting duplicate filename resolution in: C:\path\to\directory
2025-11-04 20:25:00 - INFO - Log file: C:\path\to\rename_log_20251104_202500.txt

User Input

keep the directory and log file location as variable inputs

Planner Response

I'll update the script to make both the directory and log file location configurable as command-line arguments. This will give you more flexibility when using the tool.

Edited relevant file

Planner Response

I've updated the script to make both the directory and log file location configurable as command-line arguments. Here are the changes:

New Command-Line Arguments:

1. --log-dir: Specifies the directory where the log file should be saved

   • Default: Current working directory
   • Creates the directory if it doesn't exist

2. --log-name: Allows you to specify a custom log filename

   • Default: rename_log_YYYYMMDD_HHMMSS.txt with current timestamp

How to use the updated script:

1. Basic usage (same as before):

python pattern_filename_renamer.py "path/to/your/directory"

2. Specify log directory:

python pattern_filename_renamer.py "path/to/your/directory" --log-dir "path/to/logs"

3. Specify custom log filename:

python pattern_filename_renamer.py "path/to/your/directory" --log-name "my_custom_log.txt"

4. Specify both log directory and filename:

python pattern_filename_renamer.py "path/to/your/directory" --log-dir "path/to/logs" --log-name "my_custom_log.txt"

5. With all options:

python pattern_filename_renamer.py "path/to/your/directory" --max-iterations 15 --log-dir "path/to/logs" --log-name "my_custom_log.txt"

Technical Changes:

1. Moved the logging configuration from the global scope to inside the main() function
2. Added command-line arguments for log directory and filename
3. Added logic to create the log directory if it doesn't exist
4. Configured the logging system after parsing the command-line arguments

These changes make the script more flexible and allow you to specify exactly where you want the logs to be stored, which is especially useful for automation or when running the script on multiple directories.

User Input

The exact filename regex would be - V1_A_B_C_D_E_F__.* -where A would be date format in YYYYMMDD and B would be digits of length 2 and C would be digits of length between 4 to 6 , D would be digits of length 4, E would be digits of length 3 and this part F would be 2 digit number and the rest .* would be combination of alphabets, underscore and digits. I want you to change only the 2 digit number F, by incrementing the number by 1. Make the changes accordingly to match this requirement

Planner Response

I'll update the script to match your specific filename pattern and ensure it only increments the 2-digit number F in the pattern V1_A_B_C_D_E_F__.* where:

• A is a date in YYYYMMDD format
• B is 2 digits
• C is 4-6 digits
• D is 4 digits
• E is 3 digits
• F is 2 digits (the part we'll increment)
• .* is any combination of alphabets, underscores, and digits

Let me fix that and try again:

Edited relevant file

Planner Response

I apologize for the errors. I'm having trouble with the replace_file_content tool when trying to update the script to match your specific filename pattern. The error indicates there's an issue with how I'm formatting the JSON for the replacement chunks.

The specific error is about invalid character 'd' in string escape code, which suggests there might be an issue with how backslashes are being handled in the regular expression patterns.

How would you like to proceed? I could:

1. Create a new file from scratch with the updated pattern requirements
2. Try a different approach to update the existing file
3. Break down the changes into smaller, more manageable pieces

What would you prefer?

I'll create a new file from scratch with the updated pattern requirements to match your specific filename format.

Edited relevant file

Planner Response

I've created a new script called filename_pattern_renamer.py that specifically handles your filename pattern requirements. Here's what it does:

Key Features:

1. Specific Pattern Matching: Identifies files with the pattern V1_A_B_C_D_E_F__.* where:

   • A is a date in YYYYMMDD format
   • B is 2 digits
   • C is 4-6 digits
   • D is 4 digits
   • E is 3 digits
   • F is 2 digits (this is the part that gets incremented)

2. Targeted Renaming: Only increments the 2-digit F part of the filename

3. Duplicate Resolution: Iteratively scans and renames files until no duplicates remain

4. Detailed Logging: Creates a comprehensive log of all actions taken

5. Configurable Options:

   • Custom log directory and filename
   • Dry run mode to preview changes without making them
   • Maximum iteration limit

How to Use:

1. Basic usage:

python filename_pattern_renamer.py "path/to/your/directory"

2. Dry run (preview changes without making them):

python filename_pattern_renamer.py "path/to/your/directory" --dry-run

3. With custom log location:

python filename_pattern_renamer.py "path/to/your/directory" --log-dir "path/to/logs" --log-name "my_rename_log.txt"
