1.5.3 ZIP file gets selected when using "Select All Images"

[XnSoldier]

Strange behaviour of some ZIP files getting selected when using "Select All Images". I would assume they get selected by file extensions only.

I have archives which often use "store" as a compression and contain folders and JPGs only. I always use 7zip to compress. Many of such zip files on my drive get selected as images but not all. I don't know why.

In my download folder with random software and wordpress plugins as zip files none gets selected by "Select All Images".

I tested around with Zip "FileOne.zip" and If I extract all files and compress again with 7zip or File Explorer with either compression method the FileOne will not get selected as an Image again.

FileOne was compressed about a year ago with 7zip and is 400Mb in size before I make changes.

FileOne Changes done via Windows 10 explorer:
- I extract and recompress with 7zip. Gets not selected.
- I extract and recompress with File Explorer. Gets not selected.
- I delete all JPGs, leaving just an empty main folder in the zip with the json file and an empty subfolder. Gets not selected.

- I make a file copy. It gets selected also
- I add a json file to a subfolder. It still gets selected
- I either delete all subfolders or the JPGs in the main folder of the zip. It still gets selected.
- I delete all JPGs except one, checked with different JPGs I left last. Still gets selected

I cannot share a sample zip at the moment

i can't reproduce, all image files are selected not the zip

It seems ZIP files created with ACDSee Pro 2021 get always selected as Images.

right, the zip is recognized as jpeg based

These zip files have jpeg headers inside and open as images even in irfanview and faststone. Problem with "store".

It should only be recognized by file extension I'd say
