You can use cipher.exe to encrypt files from a command line. Which of these command switches encrypts the specified directory?

To encrypt a specified directory using cipher.exe, the command switch you would use is /e.

Explanation:

The cipher command is a command-line utility in Windows that is used to manage encrypted files and directories on NTFS file systems. Specifically, the /e switch denotes that you want to encrypt the specified files or directories.

When you run the command like cipher /e "C:\path\to\your\directory", it will encrypt all files in that directory as well as any subdirectories, depending on the context and options provided.

If you're working within a command prompt, always ensure that you have administrative privileges when executing commands that modify file encryption settings, and be aware of the implications of encrypting data regarding accessibility and data recovery.
