Overview
The Multiple File Upload/Download control provides a convenient solution for end-users to upload or download multiple files during runtime. The inputs can be mapped as either FileData or a File References datatype, by default these are set to File Reference.
It's important to note that Decisions currently lacks a native scanning mechanism to verify the safety of uploaded files. As a precautionary measure, certain file types can be excluded to mitigate potential risks and bolster the overall security of Decisions. Please refer to Securing a Decisions Installation for further details on securing a Decisions installation and ensuring a safe file-handling environment.
The sections within this article are also applicable to the following Form controls:
- File Upload/Download
- File Upload Area
- Multiple File Upload/Download Area
Use Cases
Below are some real-world use cases where this functionality proves to be a valuable asset.
| Potential Use Cases | Description |
|---|---|
| Document Submission and Verification | Clients often need to submit various documents like identification proofs, income statements, and bank statements. Using the Multiple File Upload control, clients can easily upload multiple files in one go, streamlining the document submission process. A financial institution can then use the uploaded documents to verify the client's information and process applications efficiently. |
| Secure File Sharing | Institutions can mitigate potential security risks with the ability to exclude certain file types, such as executable files or scripts. This enhances the overall security and ensures that only authorized and safe files are uploaded and shared. |
| Patient Records Management | Healthcare facilities often handle numerous documents related to patient records, medical history, test results, and more. The Multiple File Upload/Download control allows healthcare professionals to upload and organize multiple files associated with each patient's profile. This simplifies storing and retrieving important medical information, leading to more efficient patient care. |
| Medical Imaging and Reports | Medical imaging files and diagnostic reports are essential for diagnosing and treating patients. With the multiple file upload feature, medical practitioners can easily access various medical images and reports within the platform. This accessibility facilitates collaboration among healthcare professionals and ensures a comprehensive view of a patient's medical condition. |
