I have about 15 million DICOM files (600k studies?) on an external disk array. Disk has DICOM files only (no software) and I'm hoping to import them into an instance of conquest, then make available to other systems via query/retrieve. Is there a way to have conquest simply inventory the files (ie put them in the database), but leave the file structure on the external disk array as-is? The folder structure is a random 8 character alpha-numeric folder for each study, and DICOM files within are that same random name + .1 .2 .3 (up to .2000 or higher for large CT studies - files do not have a .dcm identifier). Initial testing of putting a sample of the files in the "data" folder and telling the system to re-inventory failed - the files were not recognized. Placing files in a watch folder or the "incoming" folder works, but conquest seems to only inventory one single file at a time, and it seems to copy to a new folder then delete the original rather than just move the existing file. The speed of the sampling that I did was slow, so much so that my calculations say that it would take about 5 days to complete importing via this method.
What is the best/fastest way of importing these files using conquest and/or another tool (if there is something better suited for my situation).
