Quote from chaudakhYes, of course.
This is more a MWS question than a question about Gatherer Extractor.
To get correctly fullscans in MWS, you need to save all the pictures as cardname.full.jpg in the correct subfolder (whose name MUST be the set code for MWS) in the Pics folder.
Default parameters in Gatherer Extractor are set for Magic Workstation. The only thing you have to do is to choose the Magic Workstation pics folder path in Scan Options. Then you may download scans and the program will generate all the fullscan pictures in the correct subfolder of the MagicWorkstation pics folder, as the following format : Name.full.jpg
