File Mask : Reject forbidden extension before fully uploading the file

[zeehere]

Hi,
Using file masks, the uploaded file is checked after it gets fully uploaded. That wastes sometime and bandwidth. (for example uploading a 1GB file and getting rejected after upload)
Is there any way we can reject the forbidden extension file even before the file gets fully uploaded?
PS: I already clearly mentioned allowed file types, but its for those few users who don't read the instructions fully.

i don't know how to do it, but i'm sure there a way to make a message box saying something before an upload, or have a file check before the upload code.

a more experienced user would be required for setting something up like that.

Yep, using Macros, editing the template. But I agree this should be the default behavior (not allow to fully uploading a file which is forbidden).

alternativ add attribute accept to input type='file' in [box upload], e.g. accept='video/*'

Thanks for the tip. I tried this, but it does not seem to work.
<input type='file' accept='.xls,.xlsx' />
It can still accept any file.

it could technically be done with some extra code in the template.
i will add it to the to-do list
