When you refer to file names in RBA parameters, you can use the basic wild card characters * and ?.
You can use wild cards when specifying file names in actions that use files—for example, the Copy or Move Files, Email, and Delete Files actions.
The syntax is the same as in Microsoft Windows.
Some examples of wild card characters in file names include the following:
*.txt
applies the action to all files ending in .txt
.file.p*
applies the action to all files starting with file.p
.??????.pdf
applies the action to all PDF files with six characters in their names.
