When I deliver a DCP to the client on hard disk, do I have to copy the folder with the name to the hard disk root, for example Bewarethechild_FTR-1-25_F_NORSK-ES_51_2K_20200708_SMPTE_OV or just the contents of this folder? You may copy the content of that folder into the root directory, or, the complete folder 'Bewarethechild_FTR-1-25_F_NORSK-ES_51_2K_20200708_SMPTE_OV' For that single DCP, it makes no difference. However, if you want to transport multiple DCPs on one disc, you need to use folders, as some files of a DCP always carry the same name and without a folder, can not be separated. In general, I would recommend copying the folder - it also makes sure you don't miss a file.  While it is allowed to change the folder name manually (but absolutely  nothing inside that folder), if you do so, make sure you avoid any special chars outside the 'common' small ASCII charset, as some servers have then trouble recognizing the content. So, A-z, underscore, hyphen, nothing more.DCP-o-matic checks the CPL/folder name for compliance when you generate the project/DCP, but if you change it manually afterwards, you're on your own.This happens often with film titles that contain german umlaute, accents/diacritics, etc. Stay away from them - never name your DCP 'Jordi_Miró_FTR-1-25_F_NORSK-ES_51_2K_20200708_SMPTE_OV' - Carsten
