Classify files

When you classify files, you are recording information about your files—for example, you could record:

• Bibliographical information about journal articles or other publications—you can import this data from reference management tools like EndNote or Zotero.
• The date and location of interviews or focus groups.
• Any other information about your file materials that is relevant to your project.

Files created by importing bibliographical references, web pages and social media datasets are automatically classified as 'Reference' and the relevant attribute values are assigned. You can open the Reference classification sheet to check the details.

When your files have classifying information such as bibliographical information, you can:

• View all files (and their attribute values) in a particular classification.
• Run a query over all files with particular characteristics. For example, run a Text Search query across all the Journal Articles published after 1995.

Classify files manually in NVivo

To classify files:

1. In List View, select the files you want to classify.
2. On the Home tab, in the Item group, click Get Info (and hold down the mouse button), and then click Classification and select the classification for the files.

Set the attribute values for a file

To set the attribute values for a file that has already been classified (perhaps you classified multiple files at once):

1. In List View, select the file.
2. On the Home tab, in the Item group, click Get Info.
3. If you cannot see the classification and attribute values, click the disclosure triangle to show them.
4. For each attribute, you can select an existing value or enter a new one.
5. Click the magnifying glass in the Value field to see the list of existing values or clear the value and start typing. As you type, the list of existing values is refined based on what you have typed so far. If you want to use the highlighted item in the list of values, press Return. Otherwise, keep typing to refine the list or enter a new attribute value.
6. Click Done.

NOTE  You can also set the attribute values for a classified file via the classification sheet.

Set attribute values using a classification sheet

The classification sheet lists all the files in a classification and shows the attribute values set for each file.

For example, you could open the Journal Article classification sheet to see all the files that represent journal articles along with their classifying information.

You can enter or update file attribute values via the classification sheet.

Classify files by importing classification sheets

If you have gathered information about your files outside of NVivo—and the information is in a structured text file or a spreadsheet—you can import it into NVivo. For example, if you conducted a series of video interviews and have recorded the interview location, interview date and interviewee name for each interview in a spreadsheet, you can import the videos into NVivo, and then import the classifying information.

Classification sheets

Change the classification of a file

CAUTION  Changing the classification of a file may result in the loss of data if you have recorded classifying information about the file. Attribute values are only retained, when the new classification has the same attributes (matched by name and data type). For example, if you have used the predefined classification Journal Article to classify a file, and then change the classification to Government document, the values for Author, Year and Title are common to both classifications and will be retained, but the value for Journal will be lost.

To change the classification of a file:

1. In List View, select the file.
2. On the Home tab, in the Item group, click Get Info.
3. If you cannot see the classification and attribute values, click the disclosure triangle to show them.
4. From the Classification pop-up menu, select a different classification for the file.
5. Click Done.
