SmartPurger is a reliable and useful application that can purge multiple AutoCAD drawings at top speed with full control. SmartPurger is a batch processing utility that allows you to purge multiple drawings. A Unique feature is that the file time stamp can be restored. SmartPurger handles crashes so the script continues to the end and leaves bad drawings. This is extremely useful before backups and distribution of drawings.

SmartPurger is for example useful if you want to minimize the size of files before a backup or before sending drawings by e-mail, burning to CD or just to use as a quick viewer of drawings. You can even save the files to a separate folder or to a different drawing version.

SmartPurger can also execute custom script files (.SCR) or AutoLISP files (.LSP, .FAS or .VLX).

You can also set up SmartPurger to run different AutoCAD applications for different drawing file versions. Moreover you can specify the profile to be used when starting AutoCAD.

From a real project: 1773 drawings and a total size of 526MB in 2000 DWG format become 218MB in 2004 DWG format. Conversion and purging was made totally unattended.

Remember that this is a very powerful tool and make sure you understand and know what you do when you use it. Read the manual before you run it. Try on some test files/folders as a start. To be on the safe side make sure you have backups before you run.

You can run audit, zoom extents, create preview icons. Convert between versions. Purge Blocks, Dimension styles, Layers, Linetypes, Mline styles, Shapes, Text styles, Plot styles, Page Setups, Filter states, Layer states, Layer manager states (Express Tools), Line objects without length, Text objects without text, embedded VBA code, registered applications collections, Anonymous Groups, Groups.
