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 2022d\*.zip") do 7z x -r -o"e:\sortarea\" "%%F" *lycoris* xcopy /s d:\Safebooru 2022d\*lycoris* 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 ~~hand~~job 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 vulva, obvious adult actions etc) excluded from "questionable" downloads - crops done when large simple or dirty background, most artbooks de-bordered - occationally gamma correction, denoise and other nontrivial improvements made - carefully deduplicatied (with AntiDupl NET up to 4% similarity) along with several past releases Some meta-information included in tab delimited files : - **V2022D_files.TSV** post info (size, resolution, MD5 etc) with concatenated copyrights / characters / artists tags (Excel capable) - **V2022D_tags.TSV** all tags (incl. general and meta) one tag per line (not fit into 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 like '%chisato%takina%kicking%meme%' -- from the opening ```
