Queries are used to request corrections or clarifications about the data. There are four query dialogs: Add Query, Edit Query, Reply to Query, and Delete Query. The following sections explain in detail how to use these dialogs.
For studies where multiple queries per field are enabled, there is an additional dialog where users can add a new query or choose an existing query to reply to, edit, or delete. Further details are provided in Multiple Queries Dialog.

In single query per field studies there are navigation buttons at the bottom of each dialog to navigate from one dialog to another. These are not present in studies that permit multiple queries per field. Instead, the multiple query-enabled study query dialogs have a back arrow at the left top corner. The back arrow returns you to the Multiple Queries dialog.
Reasons are a way to provide additional information about existing data or to explain why data is changed. For each data field, the user can add a new reason or edit an existing reason using the Reason for Data Value dialog.

DFcollect allows users to attach documents to any record, accommodating the collection and storage of data and information in other formats. This can be useful for managing images, or other recordings, that are relevant to the data of the current record.
DFcollect is able to upload, view and download PDFs, images, audio, and video. Specifically for images, DFcollect supports JPEG (JPG), PNG, and BMP formats; for audio, DFcollect supports MP3, and WAV formats; for video, DFcollect supports MP4, and AVI formats.
Click in the CRF Menu to open the Manage Documents view. The number with the red background is the current number of documents for this record.
The view includes a list of the available documents and a preview area. Each document in the list has several attributes:
Selected for download. Checked (circle with yellow checkmark) or unchecked (empty circle).
Status. One of "primary" or "secondary" and will generally be "secondary" indicating that this document is related to the data but not the primary source of the data.
Image ID. A unique identifier for this document.
Type. What is the document type? This is a file "extension" or acronym from a list of supported types.
Arrival. The arrival time of the document to the study - when was it originally received or added.
Sender. The "sender" of the document. This may include an email address, a username and identifier for another application, etc.
If there is at least one document, the first document is opened in the preview area. To view another document, select it from the list by clicking it. Documents may not be edited.
Many document types can be previewed directly, including PDF, JPEG (JPG), PNG, and MP4 format. Other formats can be downloaded to the local computer and viewed using appropriate 'helper' software.
