Copying Files from Source Directories
As part of a job's specified conversion tasks, you can also copy other types of files from directories that contain CAD files to convert. The configuration variable MS_BATCHCONVERT_COPYEXT specifies the extensions of files that will be copied from directories specified as a source for a conversion task. For example, to copy all the files with the extension .rsc or .txt to your output directory, define MS_BATCHCONVERT_COPYEXT as rsc;txt. In the default Configuration, MS_BATCHCONVERT_COPYEXT is not defined, and the Batch Conversion dialog therefore performs only file conversions.
