Hello, @thomas-knoefel and All, First, note that I use your last version 6.0.0.36 ! In this post, I did tests about the Search in Files feature with the three N++, Search and MultiReplace features. Globaly, they all give the same results with tiny* differences regarding the MultiReplace plugin, which will require a follow-up inspection Now, in my last post to @coises, I did similar tests and this time, the MultiEeplace plugin give completely different results, compared to native N++ and Search++ ! Indeed, I got : 27,081 matches in 841 files of 1,772, in 2m 10s, with Search++ 27,081 matches in 841 files of 1,772, in 1m 21s, with B++ But only : 18,767 hits in 726 files in 1m 05s, with MultiReplace As I said, in @coises’s post, I first suspected your File Search : Skip files larger than option, in Settings, to be actived but it was not set ! Here is a screenshot of the MultiReplace dialog and of the Search Results panel : [image: 1788091671044-fc011293-9c1f-48be-a5ad-22ff996790cb-image.jpeg] So, did I do something wrong ? I also did a test on an other USB key where I put a simple subset of 7 files, from my D: key, in a Test folder I moved, within a command prompt, to that Test folder I start N++ without a session and open these 7 files I first ran the Find in Files operation, with the Directory option = E:\Test and the Filter option = *.* => 83 hits in 3 files Then, I ran the similar Find in Docs operation => 372 hits in 7 files ! So, an obvious difference ! If necessary, I could send you the contents of this Test folder, for further tests ! Best Regards, guy038

Hello, @coises, @thomas-knoefel and All, @Coises, you said : So I’m wondering, if you happen to remember, whether you tested in the order you listed, or whether you happened to test Search++ first? Well, since my previous tests were done in July 18, 2026, I don’t remenber exactly the way I used but I suppose that I first tested the native N++ search ! Thus, I decided to conduct a new series of tests. Of course, the results of the entire scan of my D: USB drive, are slightly different. Luckily, the number of matches and files containing the Fi string are identical between the Search++ search and the Notepad++ search IMPORTANT : I updated Search++ to the last 0.6.5 version, before all these tests So, this time, I first use the Search++ Find in Files dialog : I stop and re-start my W11 laptop I pluged my USB key I start N++ I ran an entire scan of my D: USB key for the Fi string, using the Search++ plugin => I got 27,081 matches in 841 files of 1,772, in 2m 10s I close N++ I unpluged my USB key I stop and re-start my W11 laptop I re-pluged my USB key I start N++ I ran an entire scan of my D: USB key for the Fi string, using the native Notepad++ search => I got 27,081 matches in 841 files of 1,772, in 1m 21s As you can see, no real difference between these tests and those of July 18 ! On the other hand, this time, the results obtained with the MultiReplace plugin are completely different. After a complete re-start of my machine I ran an entire scan of my D: USB key for the Fi string, using the MultiReplace plugin => I got 18,767 hits in 726 files in 1m 05s. Most of non text files are not scanned at all ?! I don’t understand these huge differences ? I first suspected that I allowed this option in MultiReplace settings : File Search : Skip files larger than but this option is not set ! Thus, right after this post, I’m going to post to @thomas-knoefel for possible information ! Remark that this present post is saved on a different USB drive to avoid future changes regarding the number of matches of the Fi string ! To end, @coises, you said : In any case, after weeks of running in circles, I think I will soon give up the fight to optimize performance and see what else needs work. I totally agree with this wise statement !! Best Regards, guy038

@guy038 I can creat a Python script :) but the beauty and art was finding a solution just with regex.
