How to browse the directories of a disk?

To browse the directories of a disk, you must use fListDirectory. This function is used to:

list all the directories and sub-directories of a disk.
list the directories of a disk without going into the sub-directories.
list the directories with a filter.

Two browse methods are available:

Method: Retrieving the list of directories directly.
Method 2: Using a procedure to process each directory separately.

Method: Retrieving the list of directories directly

To directly retrieve the list of directories and to process them:

Retrieve in a character string the list of all directories by using fListDirectory.
Browse the retrieved string in a loop. Each directory is separated by a CR character.
Process each directory found.

Code sample:

sDirectoryList is string
sDir is string
sDirectoryList = fListDirectory("C:\My documents\")
FOR EACH STRING sDir OF sDirectoryList SEPARATED BY CR
	// Process the sDir directory
	// the sDir variable contains the name of directory to process
END

Method 2: Using a procedure to process each directory separately

To process the listed directories via a procedure:

Create a local or internal procedure to process each directory found.
Browse the list of all directories by using fListDirectory with the procedure that was created beforehand.

Code sample:

INTERNAL PROCEDURE pProcessDir(sRootDir, sDir)
		// Process the directory found
		// The sRootDir variable contains the root directory
		// The sDir variable contains the folder name
		Trace(sRootDir, sDir)
	END

// Browse the directories
fListDirectory("C:\TEMP\", pProcessDir)
