Located in the Properties panel:

• Save Path: Specifies the directory or storage where uploaded files will be saved. Allows the file to be saved on the application server or a designated cloud service.
• Chunk Size: Allows large files to be uploaded in chunks. For example, with the parameter set to 10 MB, files can be copied into 10 MB chunks at the same time.
• Label: It is the description text that appears next to the file upload element. It allows you to specify for users what the upload area is for and what type of files will be uploaded. For example, “Please upload your file.”
• Hint: Helpful text that provides tips or instructions for uploading files. For example, “You can upload files up to 100 MB in size.” It allows you to use it for warning or informational purposes.

File Upload

The Big File Upload element allows easy uploading of files by drag-and-drop. Users can drag and drop files directly onto the component and the file will be automatically copied to the directory you specify.

For security reasons, the file name is stored as GUID (global unique identifier).

When the upload process is complete, the On Upload Finish action is automatically triggered. At this stage, you can save the information of the uploaded file. The Component returns information about the uploaded file, such as the File ID (the GUID of the file) and the File Name (the file name). The File ID and File Name data are used for later management and processing of files.
