attributes A can see thumbnail, AC does not see thumbnail

I noticed that pdf files with attribute AC do not display thumbnail and with attribute A do. Is it possible to change these attributes on the file?

In which operating system and which file viewer are you accessing or viewing these file attributes from?

Are you using command line interface?

Good morning, I use the windows 10 file explorer.

A means archive

C means compressed

Good morning, would it be possible to change this attribute? I believe this is what does not allow the thumbnail to be displayed.

Look at the help of MS Windows.

It sounds as if thumbnails are not made for compressed files, because of the high overhead of uncompressing them. If you don't want compressed files, turn off file compression.
