Hello,

I really like the new "Restrict folder tree to certain folders" feature. Unfortunately, it slows everything down extremely. The whole program becomes so sluggish that it is unusable. Interestingly, this is only the case for root folders like "C:\" oder "D:\", etc. Subfolders (D:\Subfolder\) are fine.

Thanks for reporting. I'll look into it and come back to you.

I've tested this now with various drives (network and others) where I restricted the folder tree to the top level of the drive only. None of my drives showed that behavior.

I think that it might be a combination of a rather slow drive that you are using and the fact that you have dozens of timelapse folders directly in the root of that drive that lead to this.

As a general advice, since LRTimelapse scans all containing folders with timelapse sequences when you expand them in the tree, I'd recommend to not put too many folders directly in the root and user deeper folder structures as opposed to that shallow approach.

It's better to have a deeper structure with not so many folders on one level, since this of course will give better performance, especially with slower drives.

This means, better use a deeper structure like this:

Code:

Y:\
  Timelapse SOURCE
    2022
      01 Alaska Shooting
        Timelapse 1
        Timelapse 2
      02 Los Angeles
        Timelapse 1
        Timelapse 2
  Timelapse DONE
    2022
      01 Alaska Shooting
        LRT_Timelapse 1
        LRT_Timelapse 2
    ...

And not:

Code:

Y:\
    2022 01 Alaska Timelapse 1
    2022 01 Alaska Timelapse 2
    2022 01 Los Angeles Timelapse 1
    2022 01 Los Angeles Timelapse 2
    ...

If you want to confirm your suspicion that it has to do with restricting to the root folder, I'd suggest to try to narrow down the constellation when this happens.
Move all of those folders in your root into a folder Y:\Timelapse
Then restrict the folders in LRT to Y:\Timelapse
Do you see the same behavior?
Please do some more experiments and let me know.

I did another test. This time on my brand new FireCuda 530 SSD. I created several empty folders in the root directory of the empty SSD and the behavior is the same. After moving the folders into a subfolder and changing the restricted folder setting to this subfolder, everything went back to normal.

EDIT: It stays smooth as long as the folder tree of the root folder and its subfolders isn't visible: https://youtu.be/B8_7PH7BFF8

In that screencast you have H: and H:\Subfolder both in the list of restricted folders, that will of course load all folder twice, which is not ideal.
Anyway, I think this is not your problem.
I've done some more tests on different drives with exactly the same constellation as you have and cannot reproduce this here.
Is it possible, that you have any virus scanner or "security software" blocking the access to the root of the drive?
Could you please try adding the C:\Program Files\LRTimelapse6 folder to the exception list of Windows Defender or any other Virus scanner you might be using. Let me know.

I disabled Windows Defender and the problem is still there. But I can live with this small limitation. In my opinion, it's not worth trying to find the reason as long as I am the only one with this strange behavior. Maybe it will go away when I upgrade to Windows 11 sometime...
