TitanFile allows you to upload entire folders and maintain their folder structures. Here are two ways to upload folders:
Method 1: Upload folder to a channel
First, open the channel you wish to add a folder to. Underneath the chat box, click the "Attach Folder" button.
Select the folder you want to upload from your computer. Click "Upload" and then hit "Send" to complete the upload.
You can access the folder and its contents by going to the the "Files" tab in the channel.
Method 2: Upload folder to "Your Files"
Select Files from the left side menu. Click the "Upload Folder" icon and then select the folder you want to upload from your computer. Click "Upload."
Your folder will now appear in Your Files.
