Large pause when deleting images in Viewer!

Post by Criftus » Wed Sep 07, 2005 1:54 am

Whenever I delete an image in XnView's Viewer, there is a large pause afterwards. I do not get this effect when deleting in the Browser. I think it's the thumbnail cache being updated, or the displayed thumbnails in the browser being updated as each file is being deleted. It doesn't really matter whether or not I have thumbnail caching enabled or not, or read ahead, or keeping the image in memory. The gap is very large, and makes seamless browsing/deleting of files difficult.

The directory I'm using contains 1000+ images, but that shouldn't really be an issue. The thumbnail cache shouldn't have to be updated with every deletion or renaming, only the file in question should be edited/removed, right?

Do you have this effect if you close the browser? Whihc sort method do you have in browser?

If the browser is closed, no, I don't get this problem. But so long as both the browser and the viewer are open, the pause exists. If I knew how to eliminate the tabs feature and be able to switch between the viewer & browser without having them open up separate windows for each, I guess I'd be okay. =P

The sort method I'm using is "Name (Numeric)".

Test here---

:) Hello !

- I tested to delete (definitely Shift+Del) a 1.5 MB JPG :
- In “View”, browser closed —> 0.3 second (approx.)
- In “View", browser open —> 1.5 second (delay to see the next image of the folder, 'cause this option is set @home).
- But in a test-dir. with only some pics…
- The Cache is enabled…
…The directory I'm using contains 1000+ images, but that shouldn't really be an issue. …
- Hum… IMHO, maybe smaller folders could improve the XnView running? Personally I would split such a big folder into several smaller sub-dirs. …
- XnView is certainly an excellent program, but it's not the Miracle-Cave Image

:mrgreen: Kind regards,
Claude

Eventually that's exactly what I'd like to do! =) I'm going through the images and deleting the ones that I don't need. The folder is my "dumping ground" for images I haven't had time to sort.

I don't think the amount of images in the folder is the issue though. Yes, when both browser & viewer are open, there are more processes at work than when only one is open, but why does it slow by 5x (with your test) when both are running?

I couldn't agree more! XnView is without a doubt the best image viewer I've tried. With a little more work though, maybe it could become this Miracle-Cave? :D

Oh yes. Is there any way to only have one tab open at a time? Or is there a way to disable this tab feature? I don't use it, and without it my original problem would disappear. :)

Thank you all for your time!

Option that helps?

:) Bonjour !

• Currently, there is no way to disable the tabs, but I don't think it's an annoyance : in fact, even whether the tabs would be disabled, you would have still the multi-window feature "On"…
- You can hide the tabs in the View menu, but that doesn't disable the multi-window function…
- You could attempt to tick the box >> Options >> View [x] Only one view opened
- Then, if you try : Window menu >> Tile (H or V) you will see that only one picture has a window in “View” at the same time; however, the Browser-window is shown as tiled too ! :P
- To display the tabs (no more than two in this case) doesn't change anything about the delay… I use the tabs in XnView, I guess they are handy since simple, while I don't use them i.e. in Total Commander (too much twisted !)
…but why does it slow by 5x…
- In fact, there is also the time to load / display the next image when one is deleted, this option is set @ home, but obviously you don't need it for the job you are doing… The "normal" ratio (without that option) might be let's say, 4 or so. Too long, most certainly…

• Just an idea : when deleting a lot of pics that you have to select in the browser, an option to postpone the refreshing of the current folder / cache… etc. could help, for instance when closing XnView, or from time to time with a special command in a menu… A request to post :D
