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.
