Image file order when opening with Picasa

Hello,
Currently trying trial version of an app, and noticed strange file order when browsing images in DOpus and opening these files in Picasa.

Here is example, hope it will be understandable.

In DO folder view images are sorted by name.
But once you open first image, in bottom Picasa viewer you see that file order is messed up.
Yet I'm not sure if I messed up folder sorting, or it depends on filenames/types.
Resetting folder settings to defaults, looks like have no effect, guess I didn't messed settings that much.

Folder settings are:

  • Sorting by filename

  • [x] Numberic order filename sorting

  • [x] Sort names and extension separately
    From other topics I read that these are main ones which can affect order.

Maybe this will help.

  1. User opens folder, or extracts ZIP and navigate into folder via DO.
  2. User opens first image from photoset, file order in Picasa is messed up.
  3. User navigates into folder via Explorer.
  4. Now file order is correct.
  5. Opening same first file from DO, now creates correct file order in Picasa.

Added image URL.

    (I was unable to post 3rd URL, but it looks like identical to 2nd one)

I'm not sure what Picasa does to request the file order, but it might be the same as discussed here:

If so, it's on our list to look at implementing the same thing in Opus.

If you use drag & drop, to another program, the order should be preserved. The Opus viewer also does this when opened via Opus.

Thanks for info, now I know little more why this even happens.
Will keep track on DO changelogs, because guess nothing will be changed in Picasa due to software got abandoned by Google.

Guess the issue partially is on Picasa's side.
As long time ago similar issue was reported on TotalCommander forum - https://www.ghisler.ch/board/viewtopic.php?t=28556

Old topic, but still I'm from time to time try to peak into this.
By accident found WinAPIOverride application which can monitor and show how apps interact.

Could this be it ?
On left file dropped into app via DO, files order in Picasa is "by modified"
On right - dropped into app via explorer, order of files now is "by name"

Seems I'm close but not exactly on spot. Hard to test it as when files are being opened executed via Explorer, these do behave properly via DO.
Need to have separate locations for both scenarios.
