| directory = full path and name of folder/directory to open |
| In file operations, you will often need to parse through a directory/folder and retrieve unknown filenames and other folders from it. This command opens a specified folder to begin these operations. The command returns a file handle which is used by the other commands to perform other services (like most file operators). You will use the NextFile$ to iterate through each entry (use FILETYPE to see if it is a file or folder). Remember, once completed, good programming practice dictates that you CloseDir the open folder. The example should help out alot. |

; ReadDir/NextFile$/CloseDir example
; Define what folder to start with ... folder$="C:" ; Open up the directory, and assign the handle to myDir myDir=ReadDir(folder$) ; Let's loop forever until we run out of files/folders to list! Repeat ; Assign the next entry in the folder to file$ file$=NextFile$(myDir) ; If there isn't another one, let's exit this loop If file$="" Then Exit ; Use FileType to determine if it is a folder (value 2) or a file and print results If FileType(folder$+"\"+file$) = 2 Then Print "Folder:" + file$ Else Print "File:" + file$ End If Forever ; Properly close the open folder CloseDir myDir ; We're done! Print "Done listing files!" |
