# File Reading

In this step, you will insert the files you want to be analyzed in Assay. These files usually contain results linked to your plates, such as output from a robotic platform (e.g., optical density, areas, number of cells, etc.).

The readers are already defined by the assay designer; you only need to select the files you want to analyze.

## File Import

You must provide the files for the application to analyze your data. To do so:

- Click the reader name.
- Upload one or more files at the same time:
  - By dragging and dropping your files.
  - By clicking the section labeled `Drag and Drop Files`.

Once imported, the number of files is displayed below the reader names you selected.

              
              

You can repeat this action for every file you want to import.

Click the `Raw Data File` button to have the application read your files.

## Other Actions on the Page

Before reading the files, you can:

- Delete one or multiple files linked to your readers.
- Download all files (using the top right `Download` button).
- Perform actions on the reader as explained above.

## Interactive Readers

For some readers, extra pages may be required to read the files correctly. In that case, you will use what is called `Interactive readers`.

If so, the `Raw Data File` button is replaced by a button named `Interactive reader`.

### Generic Reader

A common example of an interactive reader is the `Generic Reader`, which allows you to read any delimited text file (txt, csv, xlsx, etc.).

In `Execution Mode`, if the file format is the same as the one expected, the page will be automatically skipped, and all the information will be retrieved from the file.

## Next Step
