ProFPurge is a tool used to purge ProEngineer historical files from specified directories. During the design process it is therefore possible to go back to earlier versions. At the end of a design or project it is often necessary to purge these earlier versions. This cleans the directory up and vastly increases disk storage space. Files can be purged by going into each file individually (within the CAD package), but this is both laborious and time consuming. This utility simply purges all previous version numbers quickly and efficiently. It also checks the file-modified date and time. If a file exists which has a later modified date than that of a file with a greater incremented extension number, it saves both of these files. Any number of directories at one time, simply by 'adding' additional paths in the dialog box.
