# Uploading file fields in entity records

> Using Studio you can easily manipulate specific files of an entity record. These activities allow you to execute operations such as upload, download, or delete specified files of a specified field of an entity record.

Using Studio you can easily manipulate specific files of an entity record. These activities allow you to execute operations such as upload, download, or delete specified files of a specified field of an entity record.

:::important
The maximum size of a single file cannot exceed 10 MB, otherwise unexpected behavior might occur.

The following example contains a main XAML demonstrating how to [upload a file to Data Fabric / Data Service](https://docs.uipath.com/activities/docs/upload-file-to-record-field), after downloading it from Olympics games related Wikipedia pages.

## Prerequisite step 1: Create entities in Data Fabric / Data Service

Following the steps detailed on the [Creating an Entity](https://docs.uipath.com/data-service/automation-cloud/latest/user-guide/creating-an-entity#creating-an-entity) page, we created an entity for storing information about the Olympic games.

The **Olympics** entity has the following fields: Name (text) and Logo (file).

:::note
System built-in fields are automatically added to your entity in order to provide details about its creation.

## Prerequisite step 2: Import the entities in Studio

Import the entity inside your workflow in Studio.

The following workflow scrapes information and images about a certain Olympics edition, maps the found data to arguments, and passes them along to the main workflow.

## Step 3: Build the workflow

### Query related records

We'll use the **Query Entity Records** activity to pull up a list of records from the Olympics entity from Data Fabric / Data Service by setting up the `name` variable. This goes through all records from the **Name** field and outputs them in the `existingRecords` variable to be used in the following **If** activity.

### If

Add the **If** activity allows us to take one of the following two different courses of action, depending on whether the cont for the `existingRecords` variable is 0 or not:

#### 1. If a record does not exist, create it and assign values to it

If no records are found meaning that the `existingRecords=0` condition is met, create a new **Sequence**, use the **Multiple Assign** activity to assign values to the `olympics` and `olympics.Name` variables and the **[Create Entity Record](https://docs.uipath.com/activities/docs/create-entity-record)** activity to add the collected information to Data Service.

You can use the information available in the **Using Entities in Projects** page [Create Data Records section](https://docs.uipath.com/data-service/automation-cloud/latest/user-guide/using-entities-in-projects#create-data-records) example.

#### 2. If a record already exists, assign values to it

If a record is found, meaning that the `existingRecords=0` condition is not met, use the **Assign** or **Multiple Assign** activity to assign the value to the `existingRecords` variable.

### Upload file to record field

We use the **[Upload File to Record Field](https://docs.uipath.com/activities/docs/upload-file-to-record-field)** activity and upload the created file to the **Logo** field from the **Olympics** entity record.

### Delete the local file

Remove the file that was downloaded locally from Wikipedia to our machine after uploading it to Data Fabric / Data Service by using the [**Delete**](https://docs.uipath.com/activities/docs/delete) activity.

### Display the value of the variable in the Output panel

Add the [Write Line](https://docs.uipath.com/activities/docs/write-line) to display the value of the string variable, for this example we've added the `olympics.Name`, to the Output panel.

Once finished, your project should look like this:
