ZestDrop v0.1.0

ZestDrop v0.1.0

This release adds an English interface, lets you pause, cancel or hide each conversion, runs two jobs at once, and fixes several reliability problems.

Earlier releases were renumbered: the former v0.1.0 is now v0.0.1 and the former v0.1.1 is now v0.0.2.

What's new

• English interface. Choose English or Simplified Chinese from the tray menu (Language / 语言). The first launch follows your Windows display language, and the choice is saved. Error messages from the conversion engine follow the same language.
• Pause, cancel and hide each job. Every background job gets its own progress card:
  • Pause / Resume freezes the whole job, including FFmpeg and other helper programs, and stops the elapsed-time clock. Resume continues exactly where it stopped.
  • Cancel stops the job and removes its unfinished files. Paused jobs can be cancelled directly.
  • Hide tucks the card away while the job keeps running. A tray notification reports when a hidden job finishes.
• Several jobs at once. Two jobs run in parallel; further jobs wait their turn and are shown as waiting. Pausing a job lets the next one start. Cards are listed top to bottom in the order they started. With two or more jobs, a header shows the counts and can Collapse the cards into a pile, Expand them again, or Hide all. The tray menu can show progress, pause or resume all jobs, and cancel all jobs.
• No more 30-minute limit. Long video encodes are no longer stopped after 30 minutes; cancel them when you want instead.

Fixes

• Conversions could occasionally fail with "处理引擎未正常完成" (the engine did not finish properly), or skip the rest of a batch, even though the files had converted. This happened when the progress display read the progress file at the moment it was being updated.
• Cancelling a job, or quitting during one, no longer leaves half-written .zestdrop-… files next to your originals. Cancelling one job never touches another job's files in the same folder.
• F8 and F9 are no longer taken from other applications. They open the menu only while you are dragging files, so Excel recalculation and debugger shortcuts work normally again.
• Plain .gz files and RAR archives now get the same size and file-count limits as ZIP and TAR when extracting.
• Very large PDF pages are rendered at a reduced resolution instead of running out of memory.
• Logs and temporary previews moved to %LOCALAPPDATA%\ZestDrop\logs. The log is rotated at 4 MB, no longer records the full paths of your files, and an unwritable application folder can no longer stop the app from starting.

Download and upgrade

Download ZestDrop-v0.1.0-windows-x64.zip, extract the entire archive, and run ZestDrop.exe from the ZestDrop folder. Keep its backend, runtime, and DLLs together. The bundle includes .NET, Python, FFmpeg, 7-Zip, and the required Python libraries.

Before upgrading, finish or cancel current jobs and quit the old application from its tray menu. Extract this version into a fresh directory and launch it. A SHA-256 checksum is attached.

Requirements and validation

• Windows x64. Interface in English or Simplified Chinese.
• Office layout exports require the corresponding desktop Microsoft PowerPoint, Word, or Excel application.
• The executable is unsigned. There is no installer, auto-update, or startup registration.
• Automated checks cover the backend conversions, tool parameters, the progress stack, pausing a real FFmpeg encode and resuming it to a valid file, cleanup after cancelling, and that every interface string has an English translation. Office conversions were not re-tested for this release, and multi-monitor and display-scaling setups still need broader testing.
• Existing PDF/OCR and multi-frame image limitations continue to apply; see the usage guide.
