I would start by getting an array of filenames. This is an array of strings that contains the filepath for each of the pdf files you want to read. This can be done with Directory.GetFiles(“yourpathhere”,"*.pdf"). Store this as a string array variable.
Now use a for each activity, change the TypeArgument to string, and give it the string array variable you just created with all of the filepaths.
Within the for each loop, use the read pdf with OCR activity and save the output as a string variable. Use string manipulation (regex, split, index, etc) to pull out the name and save it as another string variable. Now you can put the string variable into a datatable, list, or directly into your application at this time.
After doing the above steps your robot will have obtained the name from all resumes in the folder listed in the original directory.getfiles() portion.
