I had a thought and used W10pro's personalization to set the wallpaper to one of the missing images.

DS then saw that image - wait -

Then I used W10 to select a similar image from the other directory.

DS did not see the 2nd selection; it still saw the first one I set with W10 (no longer active), but not the current ACTIVE wallpaper!

So now I'm really confused.

I did a test tonite with crazy results. I made six files, 5 jpgs 1 png (a save-as of the 5th jpg).

1. simple 800x600 text copied and pasted onto a 1680x1050 black background (single layer) saved as jpg; not seen.

2. same file then added 4 layers, then flattened. Not seen.

3. Same file with many effects applied. Not seen.

4 Created new 800x600 copy/pasted to same format size. Not seen -

now it gets weird:

5. same file added a drawn "X" saved. SEEN.

6. Same file saved as png. SEEN.

I'm totally clueless- why does it not see proper JPEGs created in same session with same software under same conditions, and then sees others made the same way?

I welcome any ideas!

RESOLVED!

ISSUE: Missing image files in proper directory/format.

CAUSE: Indexing turned off on target drive (C:) !

After this problem, I had a further issue with another program; in resolving that I deleted it; that led to issues; long-story-short, I lost a dual boot system and now have a normal one OS boot system.

I then ran Ashampoo's WinOptimizer and in going through the modules discovered that NONE of my drives were set for indexing, only the default Windows files. Turning Indexing back on, rebooting and letting it idle a bit while the indexing kicked off, has resolved the issue. Now DS shows all the files in the folder.

I am assuming this may relate to the other issue I posted, that of sometimes getting the same image on all 3 monitors, even though set to differing images in DS.

I hope this helps if anyone else has the same problem.

..bigger mystery is how indexing got turned off in the first place...

Wow, bummer you had to go through all that. I'm a dual-booter as well. In retrospect, I don't remember ever being 'asked' about indexing my files at all. However, I think it may be automatic if you attempt to access files from your second 'OS', whilst perusing the file structure in the first. I'll get a pop-up asking for permission to access the files and then it goes on to index the files.

It was later, while looking through some of the computer management controls that I ran into the file indexer menu.

Thanks; having looked into indexing  some more, I'm now more confused than ever; for every "you should index" there is a "don't do it" reply; even the physical setup makes a difference, SSD (don't! they say) vs SATA vs HDD, vs size/speed of cores... I read about people not seeing files, only seeing files after a particular date, slowness issues, but I couldn't find the default indexing settings for W10. My suspicion is only docs and links on C: to start, that's it. It does not index windows or any apps on C: by default, that much I saw in the indexing options window... all I know is turning it on for all my other drives solved my issues; I store most all work on another internal drive that gets BUd to an external; indexing that drive is specifically what brought back my files...who knows, it's all zeros and ones to me anyway.

Very confusing stuff, just to make the screens pretty!

I have the same problem with missing images in DeskScapes 8.x.  I have always had indexing on on my "wallpaper" directories, so that does not resolve the issue for me.

DS 3.50 finds all images and works perfectly.
