File Block
What is a File Block
The file block enables receiving responses in various file formats, such as videos, images, audios, and documents, allowing users to submit attachments in any required format. This block type ensures versatility in data collection and validation.
Why use the File Block?
File blocks can be used to receive a file from the end-user. This block ensures that the user's input is validated as a file in an accepted format. By incorporating the file block, businesses enhance efficiency in handling diverse user needs, ensuring that all necessary information is processed according to specified requirements.

Edit the File Block
You can edit File Block whenever required, even after the flow is published or in the drafts section, by following these steps:

2. Click the File Block, which you may have named differently.
3. Choose Edit from the displayed options.
4. Make the required changes to the block.
5. Publish the flow.
- If you edit a block while an end user is engaged in a live session with the bot, the previous version of the flow will be rendered until they restart the conversation.
- After making changes, it is necessary to republish the flow for those changes to be reflected in an end user's session.
- If a change is made to an input variable, it will be updated automatically across all flows where the variable is used.
Copy a File Block
If you need to reuse a block that you previously created, you can copy that block and add it to your flow as it is or edit it according to the requirement.
1. Click on the File Block you wish to copy.
2. Copy the block to be pasted on the clipboard.
3. When you want to paste that block, click the Add block icon (+).
4. The copied block will appear on the block listing section and be stated as Clipboard.
5. Click Paste Block and edit the details.
- The copied file block can be pasted multiple times.
- If you no longer need to paste it, you can clear the clipboard by clicking the close icon corresponding to the clipboard option.
- When copying an existing file block, all of its content, including any variables, will be copied as is.
- You can edit it as needed before adding it to the flow.
- Since the names of each block must be unique, the word '_copy' will be added to the copied blocks automatically; this can be changed if required.
- If you have copied a block and it is in the clipboard, deleting the copied block later will also remove it from the clipboard.

Example Use Case
A customer from the online store Zylker Electronics received their order but encountered an issue. They immediately visited the website and started a conversation with the bot.
During the interaction, the customer reported that the gadget they received was physically damaged and making unusual sounds. Additionally, the package it came in was in poor condition. Among the available options, the customer chose to attach a video file to demonstrate all the issues at once.

Best practices
- Clearly explain what type of files are needed and why. For instance, "Please upload your resume and cover letter in PDF."
- List all supported file types and any restrictions.
- Clearly specify maximum file size limits and offer tips for compressing files if needed.
- Inform users about how their files will be used, stored, and shared, ensuring compliance with data protection regulations.
A total of 500 blocks can be added in a flow. If you reach that count, you can use the jump block to create a new flow.
