Attach Digital Signatures to Multiple Files

When you attach a digital signature to a set of files, you are helping to ensure that anyone viewing the files knows about any changes that are made to the files after you signed them.

You can attach a digital signature to the following file types:

EXE and ZIP files generated by eTransmit
DWS files
DWG and DWT files that are compatible with AutoCAD 2000 and later drawing-file formats

When you attach a digital signature to a set of files, you can select the files individually from within the signing utility or drag them into the utility from Windows Explorer.
