"Remove Duplicate Files" will show a duplicate, in selected location "Computer", that is not actually a duplicate because the folder path is different!
Even searching in My Computer in Explorer will find the same file twice (something to do with Libraries).
These are the same folder paths, but show as duplicates in selected location "Computer":
C:\Documents and Settings\user\My Documents\...

Windows 7, 32 bit, Trend Micro Maximum Security, Version 11.1, Administrator rights

PS, To get to "Remove Duplicate Files" you may have to run PC Health Checkup twice; it does not always show.

Hello Pierre ! We hope you are doing great today! Welcome to the community!

We would like to clarify some information about the Duplicate File Checker/Locator feature of our Trend Micro PC Health Checkup that is built into your Trend Micro Program.
It is designed to locate duplicate files for you to free up space on your storage. Our program will check on the following criteria in order for it to conclude that they are the same file (duplicate).

1. Same File Size
- Files must have the exact file size (file sizes are measured in MBs, KBs or even GBs).

2. Same File Name
- Files must have the same file name (the one that you usually see under the file's icon).

3. Same File Type
- File types define what the file exactly is. Such file types differentiates executable files (.exe) to photos (.jpg, .png... etc). This is crucial because files can have the same name and also can have different extensions that define what type of files they are 

We need to take note that our Program depends on these criteria in order to define that the files are really a duplicate. Regardless of the file location, if all of the 3 criteria has been met,our program will classify the file as duplicate.


Also, we would like to share the easy way on how to access the Find duplicate files feature even without running the PC Health Checkup Twice. You just need to run the PC Health Checkup once and then click on the Show Details on the bottom part of that window as seen below.


Once you click on the Show Details, you will be provided with several options, you may continue by clicking on the Find duplicate files located on the right part of the opened window. See below.


After clicking on that, you will be asked for a certain criteria of the duplicate files that you might be looking for. See below.


After that, the system will be doing a scan of the files that falls under the criteria that you have set and it should provide you the option on what action that you wish to perform like deleting the files.

I really hope this helps!

Should you have further inquiries or if you wish to clarify the feature's task, please do not hesitate to comment below so we can provide our insights and help you.

Have a wonderful day!

Thanks for the answers, but, when all three criteria that you listed are true, the two Windows folder paths in my message point to the same physical file.  I used Explorer to also find the two duplicate file entries with different folder paths; then I right-clicked to open-folder-location for the first entry; then I left a txt message in that location; then I right-clicked to open-folder-location for the second entry; my previous txt message was in the second location as well.  I am afraid to use your program to test-delete one of my files, but maybe I should.
Also, clicking "Show Details" the first time for me does not show the option to click on "Find duplicate files".

Best regards


PS. Selecting location C: also gave me two entries pointing to the same physical file.

Hello again Pierre and thank you for your response.

How are you today? I hope you are having a great time.

I have tried to replicate the issue on our end. You may refer to the attached images so that I could relay to you how did I replicate the concern.

I have created two files that will satisfy the three criteria mentioned: same file name, file size and file type. I have placed the first file on a certain folder, while the second file was placed on the same folder but it is inside a sub-folder.


I have used the PC Health Check-up scan. After the scan, I have clicked "Find duplicate files" option on the Results window. Since I have placed the files on D: drive, I decided to check the whole drive for duplicate files.


As you can see from the detected duplicate files, the result name contains the path location of the files. You may click the eye icon on the right side to verify the location. You may also check the path location of the two files by clicking the Address Bar of the File Explorer window.

Please also be informed that the Trend Micro component used for scanning for duplicate files is different from the process of the search function in the File Explorer.

I hope I have been of help with your concern.

Please feel free to contact us in the community any time when you need help for Trend Micro products in the future. Have a great day!

I see this topic is a year old, but I could not find any conversation that was closer to my topic.  I have many duplicate files (most photos.) Many original files have already been deleted, leaving only multiple copies of the original.  I am afraid to select "remove duplicates" in the event that it removes all of that file, because everything looks like a copy.  If this makes any sense... can you answer?
