Remarks
Note
This function is not supported by the Microsoft Dynamics NAV Web client on devices that run Apple iOS, such as iPad. The dialog box for uploading a file displays in the Microsoft Dynamics NAV Web client, but it is disabled and the user cannot select a file.
In Dynamics NAV, the business logic is run on the computer that is running Microsoft Dynamics NAV Server and not on the client. Files are created on the Dynamics NAV service and not locally on the client computer.
UPLOAD Function (FILE) and UPLOADINTOSTREAM Function (File) are used to send a file from the client to a Dynamics NAV service.
DOWNLOAD Function (File) and DOWNLOADFROMSTREAM Function (File) are used to send a file from a Dynamics NAV service to the client.
We recommend that you use the functions in codeunit 419, File Management, to upload and download files.
