I want to be able to search for a certain criteria in drawings that are not opened. Basically have many files in my acad directory relating to different plate thickness and contract numbers. My file numbering system goes by "contract number" "n" "nest number" eg. 250n25. Each drawing has a text in the corner showing the pale thickness. When I look at any one file number, I have no way to tell what plate thickness I used on that drawing, unless I actually open the drawing. I wonder if there is a away to check for a certain criteria (plate thickness) for drawings that are closed. Often I am searching for all the files relating to a certain plate thickness and contract number, so I have to open as many as 20 files to verify the plate thickness. Sounds complicated does it not? As far as I can tell that is not possible to do with a list, if the drawing is closed.
p.s. I don't want to change the numbering system for naming my AutoCAD files, other wise I could have included the plate thickness as part of file name system.
