opening netork drive directory closes Explorer++

Post by nlcarter » Tue Sep 03, 2019 7:06 am

I'm using version and recently stumbled across an issue where opening a large (330GB) directory on a network drive (Synology NAS) and waiting for the folder sizes to be calculated caused the program to simply close. This was repeated several times. Bummer!

I then downloaded the latest dev build,, and got the exact same result. Hmmm...

My system is Windows 10 x64 and both Explorer++ versions are 64-bit.

Any help or suggestions?

First day using it. It looked great. Found the same problem.
Forced it to close and lost all tabs. Just like MS Explorer when a shutdown occurs without a logout; all gone.
Second attempt, it did load, but took several minutes to load the 65,556 items.
If the window (not tab) is closed, it takes several minutes to load all the tabs again (due to the large one).
It appears that the code was last released in 2013.

What is most desired is "remembering" all tabs even when windows crashes or gets a forced shutdown.
The long load time for large file counts is another bummer.

I would start with how many directories/files are in it.
Next would be the directory level.
Grab the free version of treesize and take a good look at it.

Walking the dir tree takes time, lots and lots, of time.
It also takes memory, lots and lots, of memory.
Both things that your os wants to keep to itself.

Windows on off as I think of it after a friend named it that way, behaves badly with proper win32 api programs.
It is an appliance front end for your M$ cloud account, {wait until you have to pay monthly to have a desktop}, not intended for use outside the walled garden of the app store.
It is also a moving target API wise, and inherently unstable as a result.

I use my own custom fork of explorer++ which I have modified for how I work, including integrating void tools everything for calculating dir/tree sizes while browsing.
I am not done working out all the bugs yet unfortunately.
I only have 10M or so files to keep track of, but it works well enough for me.

I found that that when I checked "Display Folder Sizes", it would crash when clicking on a specific folder. When I don't have that checked it seems to work ok. Hope this helps someone.
