List View slowed down by getting folder sizes

[MBaas]

I usually work in Details view, but have one folder that benefits from List View, so I use FVS. However, for long(*) time I was wondering about a strange effect when entering the folder, now I know what's happening.
The screenshot gives an idea of what's happening (left pane has folder in its "normal" state, right pane shows folder after entering):

That special folder has a not such a lot of folders, but LOTS of files - so getting folder sizes takes a lot of time...during which the folders are shown with too wide columns. When browsing over the "future place" of a folder name, that name is then drawn - as it happened with "ConfReg-09" and others.

But why is it getting folder sizes anyway in LV (they aren't shown)? Would be most welcome if this behaviour could be improved

[MBaas]

Ok, empty folders are drawn in special colour, I see. But still...does it have to take that looong (4-5 secs)?

"Show Folder Sizes" is part of the list styles that you can define in a FVS. So turn it off and save your FVS.

Ah, thanks! But are we talking of the same? Config > General > "Tree and List" > "Always show filder sizes", right? Turned that off (with that folder active), saved FV settings, used the other pane to navigate to a folder in a different part of the tree and turned it on again, saved - and suddenly folder sizes were recalculated and the other pane (with saved FV settings) was redrawn.
(And also if I navigate (in that panel) to a subfolder and then back to the folder with the saved FV, it recalculates the sizes)

So either I picked the wrong setting - or it does not behave as you think it should.

I meant this: Tools | Customize List | Show Folder Sizes

If you tick Configuration | General | Tree and List | List | Always show folder sizes then it does not help though.

[MBaas]

Ah, makes sense - except: this has been unticked all the time and still is!

[admin]

Good, then it should work as I suggested.

[MBaas]

Eh, don't understand. If it's already NOT set and I still see the delay "Calculating foldersizes" - how could I turn if off and get rid of the delay...?

[admin]

1) untick Tools | Customize List | Show Folder Sizes
2) save your FVS
3) ensure that FVS includes List Style

[MBaas]

1) was unticked
2) saved
3) yes, it is included.

And it seems now the time needed for "Calculating folder sizes" got longer - and suddenly columns get smaller (which is nice). (ah, but meanwhile I upgraded to 22.10.0014)

What if you turn off Color Filters?

[MBaas]

With the global setting in Config? That doesn't seem to have an impact.

[admin]

In the meantime I checked the code: it is impossible that folder size calculation is triggered if both "Always show folder sizes" and "Tools | Customize List | Show Folder Sizes" are disabled. (My Color Filters idea was rubbish.)

So, recheck your setup.

[MBaas]

Ok, right. So I went to C:\ and checked "Tools | Customize List | Show Folder Sizes" and then disabled it in the FVS for C:\Git - now the columns are immediately shown with the right width (no more delays)!

Thanks for your patience!
