Tips: Using wildcards in DOS

Wildcards are a very commonly used feature in DOS commands, which can help us perform some operations more conveniently and quickly. The following are some commonly used wildcard characters:

1. *: represents any number of characters.
2. ?: represents a character.
3. []: Represents a character set and can match any character in it.
