It is not possible to specify only the program name.You can use wildcards in place of drive letters and program names. Use a question mark (?) to represent single-character data, such as a drive letter. Use an asterisk (*) to represent multi-character data, such as a program name.Important: Wildcards cannot be used to represent folder names. The exact name of a folder must be specified.Correct Usage of Wildcards:Example Matched Data ?:\Password.exe The "Password.exe" file located directly under any drive. C:\Program Files\Microsoft\*.exe Any .exe file in C:\Program Files\Microsoft. C:\Program Files\*.* Any file in C:\Program Files that has a file extension. C:\Program Files\a?c.exe Any .exe file in C:\Program Files that has 3 characters starting with the letter "a" and ending with the letter "c". C:\* Any file located directly under the C:\ drive, with or without file extensions. Incorrect Usage of Wildcards:Example Reason ??:\Buffalo\Password.exe ?? represents two characters and drive letters only have a single alphabetic character. *:\Buffalo\Password.exe * represents multi-character data and drive letters only have a single alphabetic character. C:\*\Password.exe Wildcards cannot be used to represent folder names. The exact name of a folder must be specified. C:\?\Password.exe - Click Save.
