Check if Folder Exists
Can I do this in my code ?
Are there any better way ?
Public Async Function FolderExists(Client As DropboxClient, Optional Path As String = ("/Apps")) As Task(Of Boolean) System.Diagnostics.Debug.WriteLine("--- Checking Folder ---") Dim list = Await Client.Files.ListFolderAsync(Path) ' show folders then files For Each item In list.Entries If item.IsFolder And item.Name = ("Fav_Name") Then MsgBox("Folder Exists. ->" & item.PathLower) Return True Exit For End If Next Return False End Function
Yes, that sounds like a good way to handle the flow of checking for a particular folder and creating it if it doesn't exist.

To check if something exists at a particular path, you can instead use GetMetadataAsync. It would return the metadata if the item exists, or will raise an exception with LookupError.NotFound if not.
If you only want to check for one particular item, that may be easier/faster than looping through the entire parent folder listing.
Note that if you do use ListFolderAsync though, make sure you check the ListFolderResult.HasMore and call back to ListFolderContinueAsync if needed.

100% correct.
I my case, I'm using just one FOLDER to enable users to backup thier Database file of a certain version [Thier version] and when updating thier application version later, the app compairs the offline version with the online version of just One File in just One Folder.
But I will try GetMetadataAsync
and if raises an error [Not found] then I will automatically let the app do [CreateFolderArge] accordingly. What do you think?!- Greg-DBDropbox Staff
