But you do state yourself, that it is experimental (please read the appropriate menu entry).

Yes, But the experimental part is not the scanning. It is what features is used on the flat view.

I meant, that, say, in Total Commander it is possible to set subfolders level limit, that is show only the content of the subfolders up to the 2.nd level down. Sometimes it is very useful.

That is a feature that can be requested and maybe added some day.

--- Quote ---But MC will 'hang' (no really, but look like it, since the main UI can not refresh until scan is done) until it have scanned the entire subfolder structure,
so if there are lots of files it can takes a while, specially if you have a very very slow drive. But there is no way around that...
However takes a while to scan, because it must scan the filesystem before it can show the content

I am afraid, that it does hang. My computer (2,0 GHz) and HDD (7 200 rpm) are not as much slow, that the process or reading some average folder with several subfolders and some hundreds or thousands files should long a half of hour, am I right? To avoid misunderstanding I confirm again, that I have tried this feature for many very different folders on different drives and partitions, but the result was the same: for some folders (with fewer files count) it works, but for others it causes MC to hang.

Sorry I don't think so. I don't think is is really hung, I think you see that MC become "not responding" but that is because the UI can't update.
But it will release it self when it is done. It is still working and scanning the drive. check with process monitor and you see it is working.

Well, please consider my remark to be a feature request  ;)

OK, could you please estimate how long it might continue at my system (see its parameters above) to scan and show a folder with, say, about 10 000 files divided to approx 200 subfolders of 4-5 levels? Will the answer "several hours" be possible? Well, what about a folder with only 2 subfolders and 14 (yes, fourteen only!!) files, can scanning last more than 10 minutes?

I have already checked it before with Process Explorer and stock Task Manager. The current status on MC process was always [Not responding].

What I was trying to explain is that seeing "Not responsive" can be normal during flat scanning if the scanning takes long time like when there are lots and lots of files, when the scanning of the filesystem takes longer then the Windows UI Timeout. That is 20-30sec or something like that.
Seeing "Not Responsive" only means that the UI Thread of the Application is not responding and that is correct in this situation, because it is waiting for the scanning to complete. And it will "unfreeze" as soon as the task is completed.  Seeing "Not Responsive" is not always the same as the program have hung so lets kill it. The Program might still be working and in this case it normally is.

However if you only have 14 files and it "hangs" then something is really wrong with your system.
If it really hangs during scanning than something is blocking MC from proceeding like Disk Error, Security Software or a million other reason.
This has nothing to do with being "experimental" or not, It would hang anyway. 14 files is not exactly a special situations.
Flat view is ofcourse tested for normal operations, It is not like you create something and not test it at all.
All normal operations should work. It is the edge cases, The special strange situations and Special hardware that are not common that are not tested and can have issues.

So the real question is why 14 files make it hang on your system and not others. What is special/unique with your setup that makes this happen.
