During the process of learning the MFC, a directory class is established to perform the relevant operations related to the directory when the catalog is performed 1. Detect the directory to exist; 2. Establish a directory; 3. Extract the directory name from the file name; 4. Enforce the catalog ; 5. Remove the end of the file name "/"; 6. Add "/" to the directory name; the following code refers to the relevant code in Delphi, there may be related classes in the MFC, but I didn't find it. The code is as follows: // Directory.h: interface for the cdirectory class.////
