XnView Software

That setting is set to "Normal".

The same performance occurs with any file, so this one is not special, but I've attached it here anyway.

I just chose a test file randomly. I see no noticeable difference in loading speed whether the test file is alone in a directory or if it is in the original directory with ~3,700 other files.

Do you mean how long is the delay? It's about two seconds. Again, I know it's not terrible, but as many images as I open, it's a little annoying. And some viewers open the same files in about 1/4 second.

The delay does not vary much by file size. Tiny image files don't load much, if any, faster ...

No delay when starting from the browser. I just tested with a folder having ~3,700 JPG files and nothing else.

It's the same with other image file types and folders, though. Startup speed is not terrible, but much slower than some other viewers.

Yes, that is correct.

If the browser is already running, then opening an image is very fast. It just tends to take a few seconds when xnviewmp.exe is not running at all. (I think I understood your question correctly.)

I have quite a high-end Windows 10 x64 system, but typical startup speed for XnView MP 0.90 (x64) is quite slow, when launching as part of a file open. This observation is made in comparison to some other image viewers, which I will not name unless requested.

I understand that some of the really ...

Thank you. I really did look, but somehow missed it. I'm sorry.

Is there any way to prevent XnView from checking for updates at startup? I've checked settings, FAQ, registry, I Googled... Can't find a way.

Yeah, I'm not surprised. Doesn't matter--I won't use the cache anymore, since I can't exclude certain folders.

1. Go to options > thumbnails > cache.

2. Enable caching, set compression to none (may not be necessary, but that's what I use), set "use folder" to Custom.

3. Set folder to "D:\Data\XnView\Cache" (no quotes of course). Make sure folder exists (duh).

4. Allow XnView ...

I really don't think that your Japanese language environment has anything to do with it. I'm using US English and seem to have the same problems.

I'm running XnView 1.82.3, and the problem is still there. I've tried the Restore All function, uninstalling/reinstalling XnView, storing settings to the ...

Using Sysinternals Regmon, I can see what's happening, though it may not be the exact, full problem. When I try setting just the BMP association (as a test), XnView correctly creates the master file type (HKEY_CLASSES_ROOT\XnView.bmp), but it does not create the file type key itself (HKEY_CLASSES ...
