Hi, in Dolphin it is possible to open a context menu at a file. (point to a file and click the secondary button of you pointing device) Dependend of the file type you get a few action options. (e.g. Burn the file with k3b if the file is an ISO) I want to add an entry to this context menu to get the checksum of the file. Is anybody here who can lead me thougth this process? Bernd
