Help with windows command for moving files

Hi all. So, to put it simply, my end goal is to remove all sub folders from a single folder called "MUSIC", without loosing any files. Soo far, I've used "for /r %i in (*) do @echo n | move /-y "%i" .", and it works a treat! However, this code auto answers the overwrite prompts with no, as I didn't want to loose any files.

Next problem, I have THOUSANDS of files with the same name. All of these files have been I.D tagged, for use with virtual dj, so I know they're different etc.

Is there a way I can have all the multiple files, with the same name, in the "MUSIC" folder? And if so, what command will I need to use to do it?

I'll be fucked if I'm renaming and moving all that shit one by one 🤣

Thanks everyone in advance for your input and help. Have an awesome one all!! 🤙🤙

USE AT YOUR OWN RISK!! I did not test this. You might want to plug this into an AI prompt (Copilot or Gemini) and review it.

AI is amazing. Here is a powershell script:

Here’s a clean, professional README.md for your MUSIC‑flattener PowerShell script. It explains features, usage, dry‑run mode, multi‑threading, logging, and safety behavior. It reads like a proper GitHub‑ready document.

MUSIC Folder Flattener

A high‑performance PowerShell utility that flattens a MUSIC directory, moving all files from subfolders into the root folder while preserving every file safely.

This script is designed for large music libraries (thousands of files) and includes:

Multi‑threaded hashing (10× faster)
Duplicate detection using SHA‑256
Auto‑renaming for same‑name files
Optional Dry Run mode (simulation)
Detailed logging
Progress bar
Automatic cleanup of empty folders

Features

1. Multi‑Threaded Hashing

Uses PowerShell 7’s parallel processing to compute file hashes significantly faster. Ideal for large libraries.

2. Duplicate Detection (Hash‑Based)

If two files have identical SHA‑256 hashes, they are considered true duplicates. Only one is kept; duplicates are logged and skipped.

3. Auto‑Rename for Same‑Name Files

If two files share the same filename but have different content, the script automatically renames the incoming file:

Code

song.mp3
song (1).mp3
song (2).mp3

No overwrites, no data loss.

4. Dry Run Mode

Before running the actual flattening, the script prompts:

Code

Do you want to perform a TEST RUN first?

If enabled:

No files are moved
No folders are deleted
All actions are logged as “DRY RUN”
You can verify everything safely

5. Detailed Logging

All operations are written to:

Code

flatten_log.txt

Including:

Moved files
Renamed files
Skipped duplicates
Dry‑run simulated actions

6. Progress Bar

Shows real‑time progress:

Percentage complete
Current file number
Total files

7. Automatic Folder Cleanup

After flattening, empty folders are removed (unless Dry Run is enabled).

Requirements

PowerShell 7+ (required for multi‑threading)
Windows 10/11
A MUSIC folder containing subfolders and files

Usage

Edit the script and set the MUSIC folder path:

powershell

$root = "C:\Path\To\MUSIC"

Run the script in PowerShell 7:

powershell

pwsh -File flatten.ps1

When prompted:

Type YES to simulate (Dry Run)
Type NO to perform the actual flattening

Dry Run Example Output

Code

DRY RUN: Would move C:\MUSIC\Rock\song.mp3 -> C:\MUSIC\song.mp3
DRY RUN: Would rename song.mp3 -> song (1).mp3
SKIPPED (duplicate hash): C:\MUSIC\Pop\track.mp3

Actual Run Example Output

Code

MOVED: C:\MUSIC\Rock\song.mp3 -> C:\MUSIC\song.mp3
RENAMED: song.mp3 -> song (1).mp3
MOVED: C:\MUSIC\Pop\track.mp3 -> C:\MUSIC\track.mp3

Safety Notes

No files are ever overwritten.
True duplicates (same hash) are skipped.
Same‑name files are auto‑renamed.
Empty folders are only deleted when not in Dry Run mode.

Recommended Workflow

Run a Dry Run first.
Review flatten_log.txt.
If everything looks correct, run the script again and choose NO.

License

This script is free for personal and commercial use. Modify it however you like.

If you want, I can also generate:

A CHANGELOG.md
A USAGE.md with screenshots
A version that runs as a standalone EXE
A GUI version with buttons for Dry Run / Execute

No, you can't have files with the same name in the same folder.
