not to loose interesting fandom, artist or even single prominent picture and get all stuff with several clicks

Sources used (priorities high to low when deduplicating):

• safebooru.org (ID 32xxxxx) letter S in archive/folder name

134.441 images sorted and zipped according aspect ratio (dimensions 2 folders) priorities high to low :

• 47.171 “artbook pages” 7x10 (+/- 4%)
• 18.845 “wide pages” 3x4 (+/- 10%)

• 28.296 “wallpapers and computer screens” 3x2 (+/- 40%)
• 18.016 “high pages” 2x3 (+/- 40%)

and also for source and (sometimes) ID range, mentioned in folder/archive name.
You can browse pictures directly in archives with FastStone MaxView of something like it.

File names structure : %website% - %id% - %up_to_3_copyrights% ~ %up_to_5_characters% (%up_to_2_artists%).%ext% where

• %copyright% , %character% and %artist% may be used as filter for search on source booru
• %website% + %id% is unique and also may be used to get direct booru url

so you can extract subsets of interest with xcopy (from already unzipped images) or unzipping (from release on the fly) e.g.

for %%F in ("d:\Safebooru 2020d\*.zip") do 7z x -r -o"e:\sortarea\" "%%F" *sword*art*online*
xcopy /s d:\Safebooru 2020d\*sword*art*online* e:\sortarea

Transformations and filters:

• initially filtered Mpixels >= 1.2, width >= 900, height >= 900
• PNG converted to JPG (quality 94%), no animations
• downsize to 60MPix and/or maxsize 9000 px, stripes dropped or adjusted to aspect ratio 0.4 … 2.1
• manually (yep, plenty of handjob behind this release)
  • comic and 4koma, segmented scans and overtexted covers filtered out
  • real-life photos, no-character landscapes, most of line-arts and primitive chibi thrown away
  • too explicit images (uncensored nipples or bottomless, obvious hints on adult actions etc) excluded from “questionable” downloads
  • crops done (sometimes as per-frame splitting) when large simple or dirty background, most artbooks de-bordered
  • occationally gamma correction, denoise and other nontrivial improvements made
• carefully deduplicatied (with AntiDupl NET) along with past releases

Some meta-information included in tab delimited files :

• V2020D_files.TSV post info (size, resolution, MD5, rating, score etc) with concatenated copyrights / characters / artists tags (Excel capable)
• V2020D_tags.TSV all tags (incl. general and meta) one tag per line (3.029.181 rows, not for Excel)

Using some database you can play with SQL and xcopy (from already unzipped images, copypasting query result) anything you want, e.g.

select 'xcopy "d:\'||torr_path||'\'||file_name||'" e:\sortarea ' xc
from files f
join tags t on t.booru=f.booru and t.fid=f.fid
where t.tag='animal_ears' and img_size_torr>2000000

THERE ARE some rips on Sukebei tracker for Konachan and Yande-re. With nipples.
