Search by bit

[w64bit]

I am trying to search PNG files by bit. No results.
Can anyone please take a look over these commands, please?
Thank you

exiftool.exe -ext png -if "$SamplesPerPixel eq 1 and $BitsPerSample eq 1" -r -s3 -filename -d "%d%f.%e" "D:\FOLDER" > D:\FOLDER\GRAY_1-bit.txt

We need to know what command shell you are using.  These commands look good to me for Windows CMD, but would probably fail under PowerShell.

Always pay attention to the highlighting in Powershell. And PS quoting is different than every other command line.

I am using them only on Windows CMD.
With TIF, it's working.
With PNG, no.

Check to see what tags are available in your PNG images:

exiftool -s FILE.png

Only:
BitDepth
ColorType

No:
SamplesPerPixel
BitsPerSample

You are looking for EXIF tags, which are not very common in PNG files.
