BlueHarvest Preference Pane for OSX
If you move your files between Mac and PC on a regular basis, you've undoubtedly noticed a set of extra files called Resource Forks and .DS_Stores. If you don't want OSX to create these files for certain directories or applications then you need to download the BlueHarvest preference pane. A donation is requested but the download is free. You can add file extensions in the Resources tab so that resource forks for those file types won't be added. In the DS_Stores tab, you can specify certain folders or your entire hard drive so that DS_Store files won't be created in those directories.
