Acrobat Professional 7.0 has introduced the "Enable For Commenting and Analysis In Adobe Reader" feature, in this way, Acrobat Reader 6.0 and later versions can also add comments, enter forms, and save them in PDF. However, Acrobat Professional 7.0 only allows one document to be processed at a time (a dialog box will pop up asking you to confirm the storage location). The batch processing function of Acrobat cannot be used to process multiple documents at a time. So after some effort, I realized the function of converting PDF files into batch files to add comments, forms, and storage in Acrobat Reader (6.0 or later versions only, greatly reduces the workload (you can process all the PDF files in the specified directory and sub-directory at a time ).
P.S.
This program is initially intended to be released in the form of shared software, so friends interested in source code or implementation methods do not have to send me a letter.
