Hi I posted this on Reddit a couple of months back, and not sure if there has been any progress, or if the devs have even seen it: https://www.reddit.com/r/xfce/comments/1qm9o7h/please_stop_thunars_expandable_view_from_working/ Essentially, the expandable view option always works in the background, torturing my HDD when I open a large directories with my many sub directories in them. It ties to count the items in each sub-directory, even when you have expandable view disabled, so that in the case you enable it, it knows which folder can be expanded. In terms of performance this is catastrophic, with the GNOME shell telling me that Thunar has stopped working when I open a large directory, and it taking a minute or two to load the whole thing. As it's mentioned in that Reddit post: > Thunar should only ever process stuff for expandable view if it's enabled. When enabled out of the blue, show the triangle for all sub-folders in the current directory at first while it calculates stuff or goes to another directory. > > Also, IMO, expandable view should be in Thunar settings (not in View options) with a performance warning. > > I have no issue with settings being added, including things like count number of items in sub-folders / calculate size etc., but only if they are optional and don't do anything in the background when disabled. ## Version information <!--Which version of this software are you using?--> 4.20.8 <!--Which distribution are you using?--> Fedora 44 ## Steps to reproduce <!--Please, explain as detailed as possible the sequence of actions necessary to reproduce the issue--> 1. Load up a large directory with many sub-dirs in it ## Current behavior <!--Please describe the current behaviour--> Takes a long time to load large directories and unnecessary usage of the HDD ## Expected outcome <!--Please describe the expected outcome--> If expandable view is disable, no calculations whatsoever.
