What are Wildcards?

Wildcards are special characters which are used as a simple means to select multiple files. They can be seen as place holders which stand for one or several characters in the file name. DOS/Windows supports only two wildcard characters:

*	means any number of characters
?	means a single arbitrary character

Examples: following are a few examples of wildcard usage:

*.pas	stands for all files having the extension .pas
*.*	references all files
test?.txt	is resolved into all file names which begin with 'test', followed by a single arbitrary character, and having the file extension .txt

Please note that SDLRename uses both wildcards and regular expressions in the advanced mode.
