CAD tip # 13868:

Download the XrefStamp VLX file from Download, load it into your AutoCAD with APPLOAD (you may want to load it automatically so drag it to the notepad icon) and type the XREFSTAMP command to launch it.

Specify the options - the list Format, name of the label block (if any) with a multiline attribute, whether to update Comments in DWG Properties and whether to start a reactor for future updates. Or just use [apply] to create the list. It will displayed in the command line, optionally updated in your drawing's Comments and labeled in your Label block(s). If the reactor is on, any future updates of the xrefs will be reflected in your label block and/or DWG Comments.

The display format of the individual xref lines can be specified by a format string where the individual xref properties are encoded as $X (xref name), $N (file name), $P (path), $S (byte size, or $KS kilobyte size), $T (timestamp) or individual components of the date and time. The default format string is:

"\r\n[$X] = $P | $KSkB @ $D.$M.$Y $H:$M"

The default label block name is "XREFSTAMPBLOCK" (create any block with a multiline attribute). The defaults are Comments ON, Reactor ON. Unloaded xrefs are not listed.

All settings are stored in Registry so they are saved between sessions. You can also modify them in the Registry (see HKCU\SOFTWARE\Arkance Systems\XrefStamp).
