Perhaps this will help?

Hex: 0x0421
Decimal: 1057
(Photoshop 6.0) Version Info. 4 bytes version, 1 byte  hasRealMergedData  Unicode string: writer name, Unicode string: reader name, 4 bytes file version.

Perhaps best done in Adobe Bridge.

Also possible using ExifTool, as this is just a metadata entry.

Add an Adobe Bridge metadata Label - Review:

exiftool -overwrite_original -if '$HasRealMergedData eq "Yes"' -label='Review' 'DIR'

Add an Adobe Bridge metadata Rating - Five Stars:

exiftool -overwrite_original -if '$HasRealMergedData eq "Yes"' -rating='5' 'DIR'

Append a keyword "Maximize Compatibility On":

exiftool -overwrite_original -if '$HasRealMergedData eq "Yes"' -subject+='Maximize Compatibility On' 'DIR'

Or one could create a new folder and move the files, there are many options.

These commands are for the Mac OS, you would need to change the ' single quotes to " double quotes... And the double quotes to single quotes for Windows OS. Change 'DIR' to the file system path to the input folder.

ご使用の OS はなんでしょう、例えば macOS 10.14 のファインダーの情報を見るではプレビューが以下のように表示されます。

単一レイヤーで背景がある場合はどちらか区別できません。

単一レイヤーで背景が無い場合は透明部分が黒くなるかならないかで区別できますが、透明部分がない場合には区別できません。

マルチレイヤで互換性をオフで保存した場合には真っ黒で画像が見えません。

If you have Lightroom installed try importing them. If they import and view OK then it is set

Hi there,

We curretly do not have a way to check if the option for Maximum Compatibility for a file has been enabled or not.

You can check the article linked below to check further information on the option and how to keep it enabled always.

If you feel this can be added a a feature, you can raise a feature request for it at the forum linked below. This forum is monitored by our developers and they can check if this can be added in a future release.
