noticeable delay when open huge tree

[yusef88]

when open path like C:\Windows\winsxs\Catalogs
XY will expand entire tree and tends to check existence of subfolders which makes the feel of delay or lag

Windows Explorer also take time to expand a huge tree

Don't tell me you are not using the Mini Tree.

actually I have the tree hidden and still XY checks for subfolders, so I've unticked [Check existence of subfolders in tree]
it is just a note on how both of XY and Explorer, open folders. and nothing serious

But "subfolder check" only happens on startup, right? Explorer does not remember the last opened folder (LOL), so you cannot compare it anyway.
