Abstract: Systems and methods to prepare DICOM files for cloud storage are disclosed. Exemplary implementations may: extract a DICOMDIR file from a disk; parse the values to the key attributes to identify at least the values for the study instance UID and the values for the study date; group the DICOM files by the values of the study instance UID; for every group comprising the studies list, generate, based on the parse, a study name value and a viewer URL parameter; and for every group comprising the studies list, generate a separate DICOMDIR file so that the separate DIRCOMDIR file includes the group of the DICOM files that are associated with a study represented by the study instance UID.
