バッチが記録時以外のデータに応用できない

»I use a product called 20.1.0 release.

I made a batch because I wanted to convert it in bulk.

I did a record by looking up on the net and imitating.

You have created a dedicated Pre-Conversion and Post-Conversion folders on your desktop.

The file you want to convert is thrown into the "Before conversion" folder, and when batch processed, it is moved to the "After conversion" folder.

The record itself ended safely.

Because the recording was done in one file, i tried to throw in several data this time.

Select the batch menu, select a folder, and then ok.

However, you will immediately be prompted to ask which file to convert.

I don't know how to clear this.

I would appreciate it if you could tell me if you know.«

First off: Why not 21.1.1? 

That should not really matter to the issue at hand, though. 

But we may need a lot more information: 

What are the Action steps?

What are the Batch settings? 

Please post screenshots (though those may be difficult to interpret if you should run a non-english Photoshop-install). 

And have you alternatively tried using File > Scripts > Image Processor?
