JTB World’s SmartPurger has been updated to support AutoCAD 2017. Another news is, if SmartPurger runs in the background it does not take unnecessary focus from whatever other app you're working with.
SmartPurger is a batch and script utility for processing multiple AutoCAD drawings with full control. Execute LSP or SCR files on multiple drawings. SmartPurger handles crashes so the AutoCAD batch processing continues to the end and leaves bad drawings to be corrected manually. Many purge and cleanup settings are available. Useful before backups and distribution of drawings. The file's modified time stamp can be restored. What do you want to automate in AutoCAD?
