First of all: Thanks for your answer, I appeciate it.
“unfounded critism” would be if there is no fault and I am lying, but that isnt the truth, I have no reason to tell here something that is NOT correct. But I see here things other than you see them.
“incorrectly explaining” I can only tell you what I see, if your program works not correctly I can only tell you what I see on my side, not what you wanted to see me, this is also called “bug”.
This is interesting, so they are all collected in one single zip-file, this is very fine, but I am very sure that I deleted logs and reports on 04/6, but inside the support-zip are dates from 31/5, they shouldnt be still there … or should they ?
Not to be personal, but now I have to ask you if you know how your own program works. This is NOT what I am seeing here. I did a test and got (as ever) an other impression. >ou can watch the video on youtube: https://youtu.be/07HZw86eTb8. I did this video very quick, dont have time for cosmetic 
I must fairly say: That test-run did very well, it renamed all 980 files within about 30 minutes, that was really GOOD !!!
[quote]So unless you have thousands of songs in a single folder there should be little delay before matching.```
In this test-run it was a very little gap, in my last days there was a up to 15 minutes gap for about 5000 songs.
[/quote]It doesnt work on a single song basis because SongKong is trying to match songs to releases not just single songs to any version of that song on the release.[quote]
But exactly this is what I always see (and you can see in the video. Its confusing, it starts and then pauses for a very long time …
[/quote]It does not store all this processing data in memory it is stored in a database so there should not be any memory problems.[quote]
You can see in this case it was “very less” usage of RAM, but I - often - have more than 2 - 3 GB of RAM usage, last days also running an overclocked I7 at 90% CPU-Power.
This program sucks very much memory, this is one of the things I mentioned from the beginning I used it. I dont know if this is wanted that way, or a bug in SongKong or either in Java … I can only tell you what I see HERE !
[/quote]Then once a folder has been fully processed the changes to the song are saved to file[quote]
No, definitifly not, please watch the video. For me it looks not that way.
[/quote]If you actually have 100,000 files in one single folder then we have a problem.[quote]
Yes, we have one, I am only a stupid user. If this is a problem, SongKong had to solve it by itself -> If there are no subfolder, only take a amount of files “at once” and finish them …
Also it is not a solution that the user has to split the files into hundreds of folders and then starting to process every folder by hand … this takes days … no good.
BTW: If I have all songs fine sorted in folders, what should I need SongKong for? Sin of that program is to identify and sort files out of a mess … or did I missunderstood something 
[/quote]If this is the case the way forward would be use a file renaming application to reorganize your files more sensibly before then running SongKong Fix Songs. [quote]
That is the funny stuff and why I am so upset: I HAD them sorted in folders before, but SongKong didnt worked with those foilders, so I was forced to copy all of them into ONE single folder … dont ask me why ! :roll:
You can see my setting in the video, maybee I did wrong settings, but results are fine for me.
[/quote]Delete Duplicates works best when songs have been previously identified by SongKong, so should be run after a successful Fix Songs but this is not the case with how you have done it. [quote]
Yes, I know, but as long as SongKong doesnt tag my files I cant go further.
My third program I was forced to buy does a very good job with it, It cant tag, but identifies duplicates even without tags. So basicaly it seems not to be the only way to use tags. And even that I tried, but there was no difference with finding duplicates or tagging with SongKong, you can do a lower number of songs at once, but not a hugher one.
My other program had no problems to filter out duplicates out of 190000 songs at once. It took 24 hours, but ran total smooth …
As to say again: My recorded test-run did very well, also tagging-speed was VERY good, but that isnt the normal case. Also in my logs there have been many error because of “wrong audio”, but all files are OK, they are not damaged, it “must” be a fault in SongKong.
In my first run it reported over 500 damaged files, after restart, clearing database and logs it processed those damaged files, but it took up to 5 runs to get all files tagged, that is also not a normal case.
