# Data selection and download

IDC Portal offers lots of flexibility in selecting items to download. In all cases, download of data from IDC  Portal is a two step process:

1. Select items and export a manifest corresponding to your selection. 
2. Use command-line python tool or 3D Slicer IDC browser extension to download the files for your selection, as discussed in [Downloading data](https://learn.canceridc.dev/data/downloading-data) .

{% hint style="success" %}
"IDC manifest" is a text file that contains URLs to the files in cloud buckets that correspond to your selection. It will contain one line for each DICOM series, as IDC files are organized in series-level folders in the cloud storage.
{% endhint %}

## Downloading content using Cart

You will see "Cart" icon in the search results collections/cases/studies/series tables. Any of the items in these tables can be added to the cart for subsequent downloading of the corresponding files.
