Folder does exist in ftp

[claus707]

Hello to everyone,
I am using the ftp plugin to upload some files to my host. The files are uploaded if directories depending of the upload date.
The issue is here: I create this structure to upload the files.
rootpath/year/month/date
When the structure is generated for the first time everything works well, but than it gives and error because the directories exist and can't be created twice.

The code that I use is this

FTP.MakeDir(System.GetDate(DATE_FMT_YEAR));
err = Application.GetLastError();
if err ~= FTP.OK then
            Dialog.Message("Error", _tblErrorMessages[err]);
            Application.ExitScript();
       else
			FTP.ChangeDir(System.GetDate(DATE_FMT_YEAR));
			err = Application.GetLastError();
			if err ~= FTP.OK then
				    Dialog.Message("Error", _tblErrorMessages[err]);
				    Application.ExitScript();
			    else
					FTP.MakeDir(System.GetDate(DATE_FMT_MONTH));
					err = Application.GetLastError();
					if err ~= FTP.OK then
						    Dialog.Message("Error", _tblErrorMessages[err]);
						    Application.ExitScript();					
					    else
							FTP.ChangeDir(System.GetDate(DATE_FMT_MONTH));
							err = Application.GetLastError();
							if err ~= FTP.OK then
								    Dialog.Message("Error", _tblErrorMessages[err]);
								    Application.ExitScript();							
							   else
									FTP.MakeDir(System.GetDate(DATE_FMT_DAY));
									err = Application.GetLastError();
									if err ~= FTP.OK then
											   Dialog.Message("Error", _tblErrorMessages[err]);
										       Application.ExitScript();
									    else
											   FTP.ChangeDir(System.GetDate(DATE_FMT_DAY));
									           err = Application.GetLastError();
									end						   
							end					    
					end		    
			end
end

How can I check if a directory exist before I create a new one?!

I dont know if there is a specific does exist function but creating one as you say does give an error so you know it does exist.

Reading the FTP plugin help you can easily find that the FTP.List function allows you to get a complete list of files and folders given an appropriate path.

Then you can know if a specified folder does exist and, if not, create it, otherwise proceeding with the file transfer without creating the folder.

Thank you for the reply Cybergraph!
Maybe with FTP.List it can be an optimized solution, but I made a trick with FTP.ChangeDir(). In the beginning I test for an error if I can go to the directory, if I get an error it means that the directory isn't created so I create the directories.
The code is here and for the moment it works perfectly.

folder_path = System.GetDate(DATE_FMT_YEAR) .. "/" .. System.GetDate(DATE_FMT_MONTH) .. "/" .. System.GetDate(DATE_FMT_DAY);

FTP.ChangeDir(folder_path);
err = Application.GetLastError();
if err ~= FTP.OK then
			FTP.MakeDir(System.GetDate(DATE_FMT_YEAR));
			err = Application.GetLastError();
			if err ~= FTP.OK then
			            Dialog.Message("Error", _tblErrorMessages[err]);
			            Application.ExitScript();
			       else
						FTP.ChangeDir(System.GetDate(DATE_FMT_YEAR));
						err = Application.GetLastError();
						if err ~= FTP.OK then
							    Dialog.Message("Error", _tblErrorMessages[err]);
							    Application.ExitScript();
						    else
								FTP.MakeDir(System.GetDate(DATE_FMT_MONTH));
								err = Application.GetLastError();
								if err ~= FTP.OK then
									    Dialog.Message("Error", _tblErrorMessages[err]);
									    Application.ExitScript();					
								    else
										FTP.ChangeDir(System.GetDate(DATE_FMT_MONTH));
										err = Application.GetLastError();
										if err ~= FTP.OK then
											    Dialog.Message("Error", _tblErrorMessages[err]);
											    Application.ExitScript();							
										   else
												FTP.MakeDir(System.GetDate(DATE_FMT_DAY));
												err = Application.GetLastError();
												if err ~= FTP.OK then
														   Dialog.Message("Error", _tblErrorMessages[err]);
													       Application.ExitScript();
												    else
														   FTP.ChangeDir(System.GetDate(DATE_FMT_DAY));
												           err = Application.GetLastError();
												end						   
										end					    
								end		    
						end
			end
