slow browsing on network drives

[admin]

Checked it: Yes, unchecking "Include network locations" overrides "Refresh during file operations" (no refresh will happen during file ops).

I assume the other victims of slow browsing are happy now, too?

Could "Respond to file system notifications" be made to ignore network drives? Auto-refresh works well with a network drive, except when "Respond to file system notifications" is enabled.

Maybe it is easier to understand what I mean by illustrating how this would look like in the settings:

(recessed to avoid confusion about the seemingly duplicate "Include network locations")

I am hearing this for the first time. Could you elaborate?

This is an issue that we discovered 3 years ago: viewtopic.php?t=23474
In v22.20.0222, you made DisableSHChangeNotifyRegister=1 from XYplorer.ini available as setting Configuration | General | Refresh, Icons, History | Auto-Refresh | Listen (Respond) to file system notifications in the UI.

Now the question is if file system notifications can be made to refresh local drives, but not network drives.

[admin]

So, you want to enable "Auto-Refresh | Include network locations", but exclude "Auto-Refresh | Respond to file system notifications" from network locations? An option would be to add a checkbox "Auto-Refresh | Respond to file system notifications | Exclude network locations". That would nicely avoid confusion about a seemingly duplicate "Include network locations".

[daniel_m]

Yes, that is it

Having a sup-point "Exclude network locations" for "Respond to file system notifications" really sounds like a good idea. It makes sense to me, and I guess that other people will understand it too.

This is difficult to test, so for starters I'll add a tweak to the next beta (v26.30.0411). Let me know if it actually makes a difference.

Code: Select all

SHChangeNotifyExcludeNetwork=1

It works perfectly Don! Very great job! Btw it is some months ago I mentioned in some post that xyplorer must be doing something strange during network access (you answered there were not any changes). Now we got rid of it! Sometimes is necessary to review "old code" and do the changes . Again, thank you!!!

The tweak seems to work well. With Respond to file system notifications enabled and SHChangeNotifyExcludeNetwork=1, opening files with SumatraPDF from PortableApps does not make XYplorer freeze, and mounting/unmounting a USB stick does make the device show up in, or disappear from the tree

I noticed that (physically) attaching and detaching the USB stick causes my XYplorer to freeze. Merely ejecting the device (right-click > Eject) does not cause freezing. I guess because the device is technically still present and occupying a drive letter, although it's file system is no longer accessible (until it is detached physically).
When I run a ::fresh; instance of XYplorer, (physically) attaching and detaching the USB stick does not cause XYplorer to freeze.
But ... since I rarely use USB sticks, it isn't bothersome.

[admin]

Good, thanks for testing!

I'll leave it at tweak level for now.

Regarding the USB freeze: Can't explain it, don't see it here.

Try to uncheck this: Configuration | General | Refresh, Icons, History | Auto-Refresh | Refresh during file operations

thanks for suggestion. This thread is getting bigger, I hope you still have a track of what I am about here.

Unchecking this might have an effect. It is very irregular, sometimes its faster other times quite slow. I would say it is somehow on par with other competitors so I will "close" this for now. Thank you much!!
