Reserved Folder Names in Windows

by Charles Schmiesing 1 week, 3 days ago

​​​​​​We were contacted by an ITC that was processing student photos who wanted to use the folder name "CON", but that folder name is not allowed in Windows, which reports the following error:

The specified device name is invalid

We discovered that CON is reserved for “Console” on Windows, so you cannot create folders with that name.  Here is a list of other reserved names:

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