There is lag when i open child folders pressing expand button in separate tree.

Hello all.
There is lag when i open child folders pressing expand button in separate tree. TC 10.51.

Total Commander has to visit all the expanded subdirectories to check whether they have subdirectories themselves too (for the "+" button). This can take a while when there are a lot.

Can't you use Everything here? (it seems "Use "Everything" for tree function" is already being used).

Thank you for your answer. I think there is a place for optimization. Windows explorer works without any lags.

Excuse me, what do you mean?

I should have added @ghisler as I think TC can already read the tree information from everything so there shouldn't be a lag in that case.

Calling "Everything" for each subfolder wouldn't be faster than looking in each subfolder with FindFirstFile.
