Allowed file types as attachments

[Jerry12]

what file types should not be allowed as attachments in Servicenow?

by default we had xls,xlsx,doc,docx,ppt,pptx,pdf,jpg,bmp,png,txt as allowed file types

But what file types should not be allowed as attachments in Servicenow? And why should i not allow them?

I am propably assigning this question both to the wrong forum and wrong topic so feel free to correct me and i will learn.

Best regards

Hi,

Attachement restrictions are configured in below system property:

glide.attachment.extensions

You can leave it blank if you want to accept all attachment types

Refer this URL for more details:

Thanks for your answer,

The answer i was looking for was wich file types we absolutely not should allow and why.

Is there any recommendations?

Best regards

Hi,

Avoid incompatible file typesUse this property to prevent users from uploading incompatible files. For example, some browsers do not support icons in a PNG format. By not including the png file extension, you can prevent users from uploading PNG files.

Please refer to below thread and HI articles from Servicenow on the same requirement:
