App to search Duplicates in Android

Free and Open Source Software@beehaw.org – 9 points – 1 years ago

Hello, i have many folders with pictures and some of them are duplicates, is there an app that can detect that?

Here's a script from GPT4:

#!/bin/bash

# Create a temporary file for storing file checksums
tempfile=$(mktemp)

# Generate MD5 checksums for all files in the current directory and its sub-directories
find . -type f -exec md5sum '{}' \; | sort > $tempfile

# Detect and delete duplicates
awk 'BEGIN {
    lasthash = "";
    lastfile = "";
}
{
    if ($1 == lasthash) {
        print "Deleting duplicate file: " $2;
        system("rm -f \""$2"\"");
    } else {
        lasthash = $1;
        lastfile = $2;
    }
}' $tempfile

# Clean up
rm -f $tempfile

This script can be run with Termux from the root of your internal storage. Usually /sdcard or /storage/emulated/0. Do not confuse this with running from root if you are rooted.

Before using a script that interacts with your files you should backup anything that is important just in case.

Furthermore, if you comment out:

system("rm -f \""$2"\"");

By adding a # in front of it like this:

# system("rm -f \""$2"\"");

You can run the script and see what files the script would delete without actually deleting them. I would recommend doing this as I have not tested this script.

Haha thats so cool, I'll try that option as well :)

fdupes in termux

Thanks!

Also in termux:

fclones
rdfind
go-findimagedupes

If you'd find one I'd be interested in hearing what it is. As an alternative, you might be able to use a Linux app while connected through MTP.

Termux + Termux-X11 is another possibility.

I'll check it out sound interesting because i also use Termux

True, but I was thinking of something with a GUI that helps one delete duplicates selectively.

Termux-X11 makes it possible to run an X11 server for GUI apps to connect to.

FX File Explorer has that functionality (among other cleanup tools) and is generally a great file manager. It's free with limited functionality after a trial period, or a one-off fee of about three bucks for the Plus version.

It isn't open source, though.

My Android 12 Samsung phone can show me all duplicate files right in the android storage settings

Mine is running LineageOS and both the stock Gallery app and Aves Libre don't have that tool

Hm, must be a OneUI thing then

I like Czkawka for detecting and handling duplicate files, similar files, empty directories, and more.

I also like this in Linux, but isn't on Android or Termux.

Use that for Mint and worked flawlessly, nice to be able to find it in flatpak ƪ(ړײ)‎ƪ

MiX file explorer for android does this. It's free. Not sure if it's open source though, does anyone know?

It does use open source libraries.

Latest version is 6.64.3 beta.

The Google Files app will find duplicates and other things.
