I'm in the process of downloading both dataset 9 torrents (45.63 GB + 86.74 GB). I will then compare the filenames in both versions (the 45.63GB version has 201,358 files alone), note any duplicates, and merge all unique files into one folder. I'll upload that as a torrent once it's done so we can get closer to a complete dataset 9 as one file.

• Edit 31Jan2026 816pm EST - Making progress. I finished downloading both dataset 9s (45.6 GB and the 86.74 GB). The 45.6GB set is 200,000 files and the 86GB set is 500,000 files. I have a .csv of the filenames and sizes of all files in the 45.6GB version. I'm creating the same .csv for the 86GB version now.

• Edit 31Jan2026 845pm EST -

  • dataset 9 (45.63 GB) = 201357 files
  • dataset 9 (86.74 GB) = 531257 files

  I did an exact filename combined with an exact file size comparison between the two dataset9 versions. I also did an exact filename combined with a fuzzy file size comparison (tolerance of +/- 1KB) between the two dataset9 versions. There were:

  • 201330 exact matches
  • 201330 fuzzy matches (+/- 1KB)

  Meaning there are 201330 duplicate files between the two dataset9 versions.

  These matches were written to a duplicates file. Then, from each dataset9 version, all files/sizes matching the file and size listed in the duplicates file will be moved to a subfolder. Then I'll merge both parent folders into one enormous folder containing all unique files and a folder of duplicates. Finally, compress it, make a torrent, and upload it.

  Still moving duplicates into subfolders.

  Going off of xodoh74984's comment (https://lemmy.world/post/42440468/21884588), I'm increasing the rigor of my determination of whether the files that share a filename and size between both version of dataset9 are in fact duplicates. This will be identical to rsync --checksum to verify bit-for-bit that the files are the same by calculating their MD5 hash. This will take a while but is the best way.

  Checksum comparison complete. 73 files found that have the same file name and size but different content. Total number of duplicate files = 201257. Merging both dataset versions now, while keeping one subfolder of the duplicates, so nothing is deleted.

• Edit 01Feb2026 1258am EST -

  Creating the .tar.zst file now. 531285 total files, which includes all unique files between dataset9 (45.6GB) and dataset9 (86.7GB), as well as a subfolder containing the files that were found in both dataset9 versions.

  I was using wayyyy to high a compression value for no reason (ztsd --ultra --22). Restarted the .tar.zst file creation (with ztsd -12) and it's going 100x faster now. Should be finished within the hour

• Edit 01Feb2026 311am EST -

  .tar.zst file creation is taking very long. I'm going to let it run overnight - will check back in a few hours. I'm tired boss.

COMPLETE!

And then I doxxed myself in the torrent. One moment please while I fix that....

Final magnet link is HERE. GO GO GOOOOOO

I'm seeding @ 55 MB/s. I'm also trying to get into the new r/EpsteinPublicDatasets subreddit to share the torrent there.

The files in this (early) dataset 12 are identical to the dataset 12 here, which is the link in the OP. The MD5 hashes are identical.

I shared a .csv file of the calculated MD5 hashes here

archive.org is a great idea. Post the link here when you can!

rsync --checksum is better than my file name + file size comparison, since you are calculating the hash of each file and comparing it to the hash all other files. For example, if there is a file called data1.pdf with size 1024 bytes in dataset9-v1, and another file called data1.pdf with size 1024 bytes in dataset9-v2, but their content is different, my method will still detect them as identical files.

I'm going to modify my script to calculate and compare the hashes of all files that I previously determined to be duplicates. If the hashes of the duplicates in dataset9 (45GB torrent) match the hashes of the duplicates in dataset9 (86GB torrent), then they are in fact duplicates between the two datasets.

Yes! I'm not sure the best way to do that - upload them to MEGA and message me a download link?
