Create Folder

Create Folder

To create a folder in Box you will need to provide our API with a name for the new folder, as well as the id of the parent folder that you would like to create the new folder within.

cURL
curl -i -X POST "https://api.box.com/2.0/folders" \
     -H "authorization: Bearer <ACCESS_TOKEN>" \
     -H "content-type: application/json" \
     -d '{
       "name": "New Folder",
       "parent": {
         "id": "0"
       }
     }'
.NET
// Create a new folder in the user's root folder
var folderParams = new BoxFolderRequest()
{
    Name = "New folder",
    Parent = new BoxRequestEntity()
    {
        Id = "0"
    }
};
BoxFolder folder = await client.FoldersManager.CreateAsync(folderParams);
Java
BoxFolder parentFolder = new BoxFolder(api, "id");
BoxFolder.Info childFolderInfo = parentFolder.createFolder("Child Folder Name");

Name restrictions

There are some restrictions to the folder name. Names containing non-printable ASCII characters, forward and backward slashes (/, \), as well as names with trailing spaces are prohibited.

Additionally, the names . and .. are reserved names and therefore also prohibited.
