organizing‑bookmarks

organizing‑folders

Point it at Downloads, your Desktop, or any folder you like. It finds the same file saved twice, sets aside what you have not opened in months, and tells you about the huge things you forgot were in there. In Dropbox or iCloud it also clears out the duplicate copies your devices left behind when they disagreed.

+
+
media
+

organizing‑photos

+

Your pictures, sorted by when they were actually taken rather than when the file happened to get copied. Screenshots go somewhere else entirely. It finds the identical copies and the ten near-identical shots of the same moment, and never throws a photo away.

Separate screenshots from photographs + +`screenshots` counts files whose names match how the major platforms name them. +`maybe_not_photographs` counts images with no camera in their metadata, which are +usually saved images, memes, receipts, or exports. + +Screenshots are almost always safe to move in bulk, grouped by month. Photographs are +not. Keep the two proposals separate and let the user approve them separately. + +### 4. Duplicates, then bursts, and never confuse the two + +`duplicate_groups` are **byte-for-byte identical** files. They are genuinely the same +picture and safe to propose collapsing. + +`bursts` are photos taken **within three seconds of each other on the same camera**. +They are not duplicates.

Propose a structure + +Default to year and month, because that is how people look for photos: + +``` +2019/ +2020/ + 2020-03/ +Screenshots/ + 2026-08/ +Undated/ +``` + +Do not invent event names. "Beach trip" requires knowing it was a beach trip, and +guessing wrong scatters a holiday across three folders. + +### 6. Apply and verify + +Use `mv`. Re-scan and report the counts before and after. Confirm the number of +photographs is **unchanged** unless the user explicitly approved removals, and say so. + +## Judgment calls + +**Which duplicate to keep:** the one in the more meaningful location, then the one +with the more descriptive name. `IMG_4821.jpg` in a dated folder beats +`IMG_4821 copy.jpg` on the Desktop. + +**Photos with no camera and no date** are usually not the user's own photographs.
