CleanMyDesktop：一个桌面整理工具的开发记录CleanMyDesktop: Development Notes for a Desktop Archiving Tool
从文件迁移、安全备份、托盘后台到发布打包，记录这个 Windows 小工具的设计重点和踩坑修复。A concise project log covering file migration, safe backups, tray background mode, packaging, and the bugs fixed along the way.
The tool solves a small but real problem: desktop files pile up, but deleting them is risky. CleanMyDesktop moves rather than removes, keeping files in timestamped backup folders so the desktop is clean and recovery is still possible.
Core Implementation
The migration logic lives in desktop_cleaner/core.py. It creates a CleanMyDesktopBackup_YYYY-MM-DD_HH-MM-SS folder and moves desktop items into it. It skips desktop.ini and thumbs.db, and appends suffixes to duplicate names to avoid overwrites.
One important edge case is that the backup folder may also live on the desktop. Without a guard, old backups could be moved into new backups. The fix is to detect and skip archive paths to avoid recursive nesting.
Background Mode
The interface is built with Tkinter. Auto mode uses after() to schedule the next migration without an extra service. Closing the window hides the app to the system tray, where it can be restored or fully exited.
Startup is implemented through the current user's Windows Run registry key. Settings are stored in %USERPROFILE%\.cleanmydesktop\settings.json, with compatibility for the older .desktopclean config so renamed versions keep user settings.
Fixes
One UI issue was truncated Chinese time units; this was fixed with more stable control widths. Another issue was long next-run timestamps overflowing the status panel, so v1.1.1 moved that display into a fixed status area.
The project also moved from DesktopClean to CleanMyDesktop. That touched launchers, backup folder prefixes, release packages, README text, settings paths, and tests, so it was more than a title change.
Validation and Release
Tests cover migration naming, duplicate files, backup-folder skips, path containment, and folder-size calculations. Before release, the project runs python -m unittest discover -s tests and python -m compileall desktop_cleaner tests scripts.
The release script copies source, assets, launchers, README, Release Notes, and LICENSE, removes cache files, then builds CleanMyDesktop-version.zip. The release structure stays predictable.
Summary
CleanMyDesktop is not about complex features. It is about reliable boundaries: no overwrites, no accidental recursive moves, recoverable backups, clear exit behavior, and repeatable releases.
