Upload Multiple NFTs

Uploading one NFT at a time works well for small collections, but the amount of time will be prohibitive if you upload a 5K or 10K collection. For that reason, we have multiple uploads. To upload a 10K collection, you'll need to create a folder with all the images and a file named metadata.csv with the properties for every NFT.
The first step is to go to the NFTs tab, click on New NFT and select Multiple NFTs.
Then it will show what to do next. There is a link to the metadata.csv file with sample information and how you must organize the information
The structure of the folder must look like this:
The metadata.csv has some mandatory columns like image and name, the remaining columns are the NFT properties. Download a sample file here.
The first column in the file has to be the image.
When you click Upload folder, it will check the metadata.csv and look for errors. If there is no error, it will show the message "Metadata file verified correctly."
Next, you can click on Create NFTs, which will start the upload process. During the upload, please don't refresh the page.
Once the upload process is finished, it will show all the NFTs.

Upload multiple NFTs with multiple files inside

To upload multiple NFTs with multiple files inside is a similar process; the difference is in the metadata.csv format.
When you add multiple files, the 1rst column must be the one that indicates how many files has every NFT (without taking into consideration the main image). The column's name is up to you; we use files as the first column's name in this example. Since every NFT will have the main image plus two files, we set this value to 2.
The image column is required. Every row will represent a file, and the file's name is in the filesystem. As you can see in the first NFT, the image is called 1.png, and the files are called 1.1.mp4 and 1.2.mp4, respectively.
The name property is required for the main image but not the files. In this example, we wanted to identify them and assign them names.
The files can have their own properties; for that, add new columns and fill the properties.
