Hi @Legalr
Your use case is not clear. Do you want us to attach only these extension files in the attachment?
If yes, then you need to change the system property.
Restrict attachment file extensions
The glide.attachment.extensions property restricts the file extensions that users can upload as attachments.
Restrict attachment file extensions to prevent users from uploading invalid file types and file types that may be more likely than others to contain viruses or malware.
Note: This property does not restrict attachments based on the actual file type, only based on the extension. To enable MIME type validation, which validates that the MIME type of a file matches the file extension and can block attachments that do not pass this validation, see .
- Navigate to .
- In the Attachment limits and behavior section, locate the List of file extensions (comma-separated) that can be attached to documents via the attachment dialog property.
- Enter the file extensions and click Save.
If no extensions are specified, then all extensions are allowed. However, if any extensions are specified, all unlisted extensions are restricted. Listed extensions should not include the dot (.) prefix or spaces after commas. For example, enter xls,xlsx,doc,docx.
