Get reserved file names in Windows

Question

It's known, you can't create a file with name con (con.txt for example) in Windows. So, in my application user can input a custom file name (not via SaveFileDialog, just textbox to input name, not full path), and I want to show an error message, when user inputs invalid file name. Is there a way to get full list of reserved Windows file names (con, prn, lpt and so on)?

Answer 1

Do not use the following reserved names for the name of a file:

CON, PRN, AUX, NUL, COM1, COM2, COM3, COM4, COM5, COM6, COM7, COM8, COM9, LPT1, LPT2, LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, and LPT9.

Also avoid these names followed immediately by an extension; for example, NUL.txt is not recommended.
