Excel XLSX recognized as ZIP file

L4 Transporter

Hello,

I configured a File Blocking profile to block specific file format (like Exe, PE, RAR, etc).

Unfortunately, this profile also blocks Excel file in new format (.XLSX).

No problem, with the old format (.XLS) !!

After reading some doc, it seems that .XLSX is a compressed archive with a directory structure of XML text documents.

How can I block ZIP file and allow .XLSX file ??

Regards,

HA

Hi HA,

You are correct - the new Microsoft Office format (XLSX, DOCX, etc) is really a compression file, which is why it will trigger the ZIP file signature.  Unfortunately, in order to allow Microsoft Office 2007 files, you will need to also allow ZIP files.
