It's not 100% correct...Because they can't find the exact ID..They just found the name......Proof here...

Nice tool but not very useful. My library of over 11K movies does not have any duplicates. Yet it found 524 duplicates. Upon closer inspection I found that it flags different/unique movies with same names in the same year as duplicates. Here are some examples with name, year and IMDB unique identifier for reference. Instead of checking names and years the tool should ideally check for IMDB/TMDB unique identifiers to flag duplicate. BTW I use TinyMediaManager for maintaining my library. But I was curious about this tool.

I found this really useful.  After doing comparison of different rip qualities, I sometimes forget to remove them.  This has helped me find quite a few duplicates, and also a few that were the same with different names.  The end result can be quite a significant space savings.

As for some that had different names and remakes, I didn't find it difficult distinguishing between them.  Especially when I have the year listed on each folder. 
 

Thank you for sharing this!!!

Hi all,

FYI I made a fork of the original Duplicate Movie finder, with a better UI and improved duplicate detection.

Please give it a try and let me know your opinion about it.

Where the heck is the link to use it?  Don't see it anywhere in the post.

Did you try running index.html in your browser?

Thought I'd mention that sometimes files don't have the same name as their folder.    I haven't dug into this duplicate searcher, but I thought I'd mention it in case that issue could be confounding the search for some people.

 

. . . 

I user directory opus as my file manager.  It's not free, and a little pricey for an app (but the license lasts for years so I consider it fairly reasonable). I love it.  There may be similar functionality in other 3rd party file managers.

 

. . . 

In that case I outlined above, where media file's names don't reflect their folder name meaningfully for whatever reason,  I use my 3rd party file manager "Directory Opus" as follows:

- I open the folder that contains all of the media files

- I change the view to "flat view" in directory opus (icons for that at the top of it's interface) , so that all of the files are exploded out into a main listing instead of  being hidden inside of their folders. 

- From there I can hit the top column heading to sort by "Type" so that all of the video files appear together in one nice block.  

- I click the topmost file with a media suffix, hold shift, and select the bottom one to select all. Otherwise CTRL + click individual media-suffix files that are named strange.

- In my case, I set the tiny scriptlet detailed below to a button on the top area of the directory opus file browser/manager.

- clicking the button, all of the selected media files are renamed to the name of their parent folder.

. . . . .

 

. . . . . 

Here is the "script" that does it in directory opus

 

Method 2: Using a Button/Hotkey Command

For frequent use, you can create a custom button or hotkey that runs the command directly. 

Right-click on an empty space in a toolbar and select Customize.

Drag the Rename command to the toolbar or double-click to edit an existing button.

In the button editor, modify the command to:

Rename PATTERN * TO {parent}.*

Save the changes. Now, clicking this button after selecting files will perform the rename operation instantly. 

 

Method 3: Using a Simple Inline Rename Shortcut (Opus 13+)

In newer versions of Directory Opus, a built-in shortcut is available during inline rename mode. 

Select the file and press F2 to enter inline rename mode.

Press Ctrl + / to automatically insert the parent folder's name while preserving the file extension.

Press Enter to apply. 

 

. . . . . . . 

The bulk rename utility might be able to do something like that too, not sure.  I typically use that utility to truncate names down closer to just their title.  In some cases, I do this either before or after the operation above, in order to cut down long winded descriptions in folder and/or file names.

. . . 

 I think if both the bastard filenames and the long form folder/filenames are addressed, it would probably make searches and indexing easier for apps.

I had some of the same issues with getting it to work via the clicked html link.

I also downloaded the html files locally and tried that way.  In firefox, it says "the connection used to fetch this resource was not secure". 

Quote

fetchLibraries file:/// (deleted dir this for this post)/ Emby Duplicate Finder_files/script.js:40:28

findDuplicates file:/// (deleted dir this for this post) /Emby Duplicate Finder_files/script.js:15:33

onclick file:///(deleted dir this for this post)//Emby Duplicate Finder.htm:1:1

In chrome, using my emby local ip address and port, it just said "no duplicates found in any library" , but that message popped up instantly so it obviously didn't get access to search over time.

. . . 

I have enough security on my machine that I don't want to strip everything for this, so I'll probably just pass for now.

Directory opus has a duplicate file finder, so maybe I can make that an overall wildcard somehow and isolate it's search to the shared emby folders.  Typically it's used to search by a specific file name, but directory opus is practically a whole OS and can do a million things so I might be able to get it to work like that.

 

Edit:   This method might work in directory opus, but may require " * " to make the file name a wildcard on one or both ends.

Quote

To search for all similar filenames without inputting a specific name in Directory Opus, you should

use the Duplicate File Finder tool and select the "Filename only" comparison method. 

 

Steps to Find Similar Filenames

• Open the Duplicate File Finder:

  Select the Find Duplicate Files command from the Tools menu. The duplicate file finder panel will appear at the bottom of the Lister in the Utility Panel.

• Specify Locations:

  In the Find in section, add the folders or entire drives you want to search. You can search multiple locations at once.

• Choose Comparison Method:

  Find the Comparison method drop-down menu.

  Select Filename only. This tells Opus to consider any two files with the exact same name as a duplicate, regardless of size, date, or content.

  Alternatively, selecting Filename (no extension) will match files like "photo.jpg" and "photo.png", which is useful for finding similar base names.

• Define a General Filter (Optional):

  If you only want to check a specific type of file (e.g., only images), you can use the Filter option or enter a wildcard pattern like *.jpg|*.png to control which files are considered by the search. To do this, click the Define Filter button or use the input field in the Duplicate File Finder panel.

• Start the Search:

  Click the Find button to begin the search. The results will be displayed in the file display, grouped by filename. 

This process will list all instances where a filename appears more than once across your specified locations, effectively showing you all "similar" (i.e., identical) filenames without needing to type a specific name in the initial search

. . . 

 

 

This emby search tool is cool looking idea for those that get it to work though.

Just since I mentioned it,  I found a way to use opus to search loosely for similar names:

Quote

To find similar filenames with identical extensions in Directory Opus (e.g.,
A.bird.in.flight.jpg and a.bird.in.flight.from.the.nest.jpg), use the Duplicate File Finder in "Similar File Names" mode. Set similarity to a low percentage (e.g., 50-70%) to catch loosely related names, and ensure the filter is set to match extensions. 

Steps to find similar filenames:

• Open Duplicate Finder: Go to Tools > Find Duplicate Files (or press Ctrl+F and switch to the Duplicates tab).
• Add Locations: Add the folder(s) you wish to search.
• Configure Similarity: In the search options, select "Similar File Names" (instead of exact matches).
• Adjust Threshold: Set the similarity percentage lower (e.g., 60%) to allow for the added words like "...from.the.nest".
• Match Extensions: Ensure the option to include file extensions in the comparison is active so that .jpg files only match other .jpg files.
• Run Scan: Click the Scan button to generate the list of matches. 

For more precise results using a.bird.in.flight as a base, you can use the Advanced Find (Ctrl+F -> Advanced) with a wildcard search like *a.bird.in.flight*.jpg to list files containing that specific substrin

 

There is a little function button next to the search type in opus, but even when I set it to "similar" names, it doesn't work like the subject of this thread does, at least what I've tried so far.   Will see how it goes.
