If you are searching for Revit files on your local hard drive, try using the search tool Everything – its super fast. If you want to index local network shares, and you are:
using a 32-bit OS – you can use Windows Search and the Add-in for Files on Microsoft Networks.
using a 64-bit OS – you can use Google Desktop (Search), and then add the local shares as additional paths.
If you are using Google Desktop, you can also improve the indexing of CAD files by installing the ‘General CADD Pro’ indexer:
After installing Desktop Search, download, unzip the zip file and run SetupGeneralCADDIndexer.msi to install the General CADD Desktop Search Plug-In.
