The SysTreeViev32 directory tree is so starting from 20 thousand entries very slowly, with over 1 million of entries it takes an eternity.
So I could not use this component, especially since I need the tree-list-View-grid-hybrid, so I just programmed it myself, I decided not to build on the standard SysTreeViev32. or expand it. Since it is way too slow and I needed something really fast that will not go to the knees at over 1 million of entries.
There was no other choice but to program a tree-list-view hybrid. Because only if yourself write the program, you can easily optimize and expand it in the future.
In my tree-list-view hybrid, billions of entries can theoretically be made, because in the future it will not be uncommon for the growing hard disks to have more than one billion files and folders.
