Any way to Limit what type of files can be uploaded

Hi All, I’m having this recurring problem where users upload a . AVIF image file, and because of the rest of an automated workflow I have in make.com, that type of file breaks my automation. I know I can probably do a file conversion down the line, but is there any way to not allow a file type right at the start in Gilde?

If it’s inside a custom form, you can use some computed columns to extract the extension of the file uploaded.

If it’s not AVIF, you don’t allow them to submit the form and show an error message with a Hint component.

That’s fantastic, thank you so much as always. hey while I have you, here’s my other user bug. Multi image uploads, I have the submit BTN set that it only appears when it see’s files, but some users hit submit as soon as it appears, then complain that files are missing. Now I can’t tell how many they are going to upload but any ideas on holding off the button until they are all uploaded?

Here you go.
