I have a use case where I would like for the user to upload a csv to the backendless file service and then immediately import that data into a data table. I am using the target directory logic to create a custom path each time with no issue.
In the On Upload Success event there is a context block called Uploaded Files. If you enabled the File Uploader Button component’s option Multiple Files, the value of Uploaded Files is the list (array) of URLs to uploaded files, otherwise - the value is just the URL of the file.
