Multiple File Upload Functionality

Unknown

Im having some trouble with the file upload controls. Ive found some documentation on this subject but could use some clarification.

It appears Multiple File Upload and Multiple File Upload Area have same functionality but later adds drag and drop capability? Are there other functional differences, or a preferred approach assuming random assortment of file uploads? Would Decisions have a good starter list of allowed extensions (that avoid executables, etc.)?

[font=Roboto, Arial, Helvetica, sans-serif]Hello, I believe those two controls are functionally the same. [/font]
[font=Roboto, Arial, Helvetica, sans-serif]One just eliminates the step of creating a new popup to add files. (The Multiple File Upload Area is basically the popup that is created when you click on Multiple File Upload.) [/font]

[font=Roboto, Arial, Helvetica, sans-serif]Also, I do not believe that there is a restriction on the kind of files those controls accept. You can even have a mix of file types. But what kind of process do you intend to have an assortment of files for? Because you might need to setup a rule, or rules, to make sure your process only receives the file types it accepts for calculations or logic.[/font]

[font=Roboto, Arial, Helvetica, sans-serif]These are just general reference files for order placement e.g. pdf, txt, msg, etc. nothing we process -- other than customer wants to store these to file share location. [/font]
For safety/security reasons would like to block upload of executables (exe, com, msi, etc.). However, I don’t see a black list (just a white list). Is there system setting, etc. their administrator can configure to block these file types? Or do we need to control using predefined white list?

There is a way to block certain file types from being uploaded on a form.

Under System > Settings > Portal Settings > Globalization Settings is a property called "Extensions Not Allowed."
Put a blacklisted file type per line there to disallow users from uploaded them. When a user tries to upload a blacklisted type on a form, theyll received a popup.
(In the example below, I tried uploading an EXE file. It was not added to the list and the popup occurred.)

Hi.. I have uploaded my file, I want to store it in a POSTGRESQL. But Im not able to convert the type from File Data to Bytea. Im getting some error at the mapping part while inserting the values in the database.
