Your datfiles use rebuildto tags which are used in the rebuilder to create the subfolders. They aren't used for scanning. It's just a rebuilder feature (which may become obsolete with setsubfolders anyway). If you use these datfiles and rebuilt the files without disabling the rebuildto usage, you would have to setup more rompaths (for each mentioned subfolder), since you would have a documentation\documentation folder. First is the rebuildto entry, second is the actual setname. Since rompath\setname is the rule for scanner settings, you'd have to setup another rompath to the reuildto folder.

If you ask me it's a not well desgined dat. You should use setsubfolders instead of rebuildto.

rebuildto Documentation
rom ( name EAC.txt size 62842 crc 0x7b861aed md5 0x0fd3ca8d05750fedc5269f2a074d06ff sha1 0x40612fddc2e25967b31e62617aa36af3e3b38918 )

would become

rom ( name Documentation\EAC.txt size 62842 crc 0x7b861aed md5 0x0fd3ca8d05750fedc5269f2a074d06ff sha1 0x40612fddc2e25967b31e62617aa36af3e3b38918 )


If the other folders (languages etc...) belong to the set as well I would combine the single sets to one..


rom ( name Languages\Czech.txt size 141833 crc 0xefb80515 md5 0x119d2a7aa34....
rom ( name documentaion\EAC.txt size 62842 crc 0x7b861aed md5 0x0fd3ca8d05750fedc5269f2a074d06ff sha1 0x40612fddc2e25967b31e62617aa36af3e3b38918 )


etc....
