The best time to survey a territory is when it has become so cluttered that even the master is lost. The desktop C:\Users\Min\Desktop received its first comprehensive census.

I. The portrait of a million files

A 233-second read-only scan (without moving, modifying, or deleting any file) gave the panorama: 215 loose root files (3.83 GB), 69 folders, 1,077,805 files inside folders (42.46 GB) — about 1.078 million files and 46.2 GB in total (excluding 222 code-cache subtrees such as .git/node_modules/pycache). The portrait of the 215 root files: 23 installers (3,053 MB, two WorkBuddy versions, Kilo, dsh, opencode, the Tencent Video APK…), 93 images (including 7 DSLR RAWs), 26 novel txt files (The School Flower Bodyguard 47.7 MB, Jian Lai, A Record of a Mortal Journey, Xian Ni, Sword Snow Stride, Lord of the Mysteries…), 43 shortcuts, 4 description MDs. The 69 folders were sorted into eight themes: code repositories/projects 19 directories (1,051,105 files / 23.65 GB, with BiliRoamingX-Build at 759,773 files / 13.8 GB the largest desktop directory), games/AFK scripts 13 (MaaGakumasu 3.7 GB), study materials (IELTS 6.24 GB), novel corpora 7, character-card/world-book projects 19 (eight Plunder System sets plus Doupo, SAO, Oregairu, Saekano, NIKKE, Fate, Pirate Myth, Jin Ping Mei — months of rations from the book-splitting armies all here), image assets, four toolkit versions, and system miscellany.

Three “report-only, not one touched” findings: universal-downloader-zcode-mod and zcode修改版 are file-by-file MD5-identical (cd0075bad77e2c1a4e7ed90f989ed2cb, both clones of the b218bb2b old snapshot from 09-12); decompilation products (smali tree + jadx tree) about 15 GB are regenerable intermediate artifacts; privacy-sensitive items (passports and bank statements in the English materials, the wxdump workspace, github-recovery-codes) were flagged.

II. Naming and removal

The master came step by step: first the installer list, then which of the two zcode copies to keep. The list came with install status and redundancy judgment (three obvious redundancies: WorkBuddy 5.7.6, ud 1.0.31, MyBili 1.2.7 totaling 557 MB; eight deletable candidates totaling 1,420 MB; five of them the master’s own project outputs). The two zcode copies were confirmed by full-file MD5 comparison to be byte-identical, same-origin same-version, with no new or old — both old ancestor snapshots of the live repository (already at c3d4f11 ai.1.0.41). The nature of BiliRoamingX-Build was also explained: a bilibili smali decompile tree, an intermediate artifact of an early project.

One command from the master: the 23 installers + the zcode redundant snapshot + BiliRoamingX-Build. A pre-deletion check was done first (five project outputs confirmed to have backups elsewhere), then precise removal — top-level entries 284→259 (exactly 25 items), 0 created or moved, about 16.98 GB freed (installers 3,053 MB + BiliRoamingX-Build 13,849 MB + zcode修改版 486 MB), and the C: drive went from 14 GB back to 43.22 GB free. The receipt was written to disk (with the full deletion list, MD5s, and retained-item verification). Two reminders were honestly submitted: the TencentVideo APK was in the deletion range (deleted per instruction, MD5 084b26a0 recorded; rea already has the decompiled source and report); the two MyBili copies had been the only copies on disk (the GitHub token was already invalid).

III. The craft of two finales

The killed du task accidentally became an independent re-verification: in the post-deletion snapshot both BiliRoamingX-Build and zcode修改版 had vanished while ud-zcode-mod remained — consistent with the difference-set verification. It also exposed a caliber difference: du reports disk allocation and includes the excluded .git/node_modules, generally larger than content statistics (AlasApp 2,639 vs 1,702 MB, the difference source being .git) — this lesson was written into the windows-disk-inventory-cleanup skill, and future inventories will not mix the two size columns.

The last act was the甄别 of a false alarm: the deletion receipt showed BiliRoamingX-Build still existing (exists=yes) — re-verification found it was two rd processes fighting over the same tree (the first, interrupted by a tool timeout, was actually still running, and a second was launched; they Access-denied each other, and each exist check reported yes in one and GONE in the other). The final arbiter was the [ -e ] measurement: the directory indeed does not exist. The lesson was written into the skill: never run two concurrent rd on the same tree; deletion completion is judged only by [ -e ] measurement plus the pre-deletion manifest JSON difference — rd’s own output and exit code do not count.
