MjazTools AutoPopulate is a Joomla component that automatically adds files from a directory to DOCMan. Instead of uploading each file individually, and filling out the document details over and over again, you can now upload all files using FTP. Then create some default settings in AutoPopulate and choose a category. AutoPopulate will create document entries for all your uploaded files.
Features:
* Add thousands of files to DOCMan in a few clicks!
* Control panel for document defaults
* Clean up document titles eg. 'my_file.ext' -> 'My File'
* Make multiple documents for the same files
* New! Use cron jobs to auto-AutoPopulate
