Nebula 1.4.0 是一次大幅扩容的功能版本。传输更完整:上传断点续传(中断后从已传分片继续)、全局带宽限速、随时取消(下载 / 上传 / 迁移),以及传输列表持久化——关掉重开,未完成的任务还在,点一下接着传。存储管理更进一步:存储类型转换与归档取回(单个 / 多选 / 整个文件夹)、新建 / 删除 Bucket、对象 Content-Type 查看与编辑、文件夹级递归下载 / 迁移 / 删除、MD5 完整性校验、文件夹 / Bucket 大小统计,以及按大小 / 类型过滤的搜索。界面也从只有中文变成中英双语,一键切换。

Nebula 1.4.0 is a major feature release. Transfers are more complete: resumable uploads (continue from already-uploaded parts after an interruption), a global bandwidth cap, cancel anytime (download / upload / migration), and a persistent transfer list — close and reopen the app and unfinished tasks are still there, one click to continue. Storage management goes further: storage-class transition and archive restore (single / multi-select / whole folder), create / delete buckets, view and edit an object’s Content-Type, recursive folder download / migrate / delete, MD5 integrity verification, folder / bucket size stats, and search filtered by size / type. The UI is now bilingual (Chinese / English) with one-click switching.

版本信息 | Release Information

传输能力升级 | Transfer Upgrades

  • 上传断点续传:大文件分片上传,每传完一片就把会话(upload id + 已完成分片)落库;中断后重发同一文件会复用会话、跳过已传分片,只补剩下的。
  • 随时取消:下载 / 上传 / 迁移都可取消,停在干净的分块边界;取消不丢已传进度,面板里点「继续」即从断点续传。
  • 全局带宽限速:令牌桶实现,在设置里填 KiB/秒 即可,对所有传输统一生效,调整立即作用于进行中的任务。
  • 传输列表持久化:任务列表存本地 SQLite,重启后恢复;关 App 时还在传的标为「已中断」,可手动续传。

Resumable uploads persist the multipart session (upload id + completed parts) after each part, so re-uploading the same file reuses the session and only fills in the rest. Downloads, uploads and migrations can be cancelled at a clean chunk boundary — cancelling keeps progress, and a Continue button resumes from where it stopped. A token-bucket global rate limit (KiB/s in Settings) applies to all transfers and takes effect live. The transfer list is persisted to SQLite and restored on startup; tasks still running when the app closed are marked Interrupted and can be resumed.

存储类型管理 | Storage-Class Management

  • 查看存储类型:对象详情显示所在层级(标准 / 低频 / 归档 / 深度归档 …)。
  • 转换存储类型:把对象转到低频 / 归档层省钱,支持单个对象、多选、整个文件夹。
  • 归档取回:归档 / 冷归档对象取回解冻后才能下载,支持单个 / 多选 / 整个文件夹;混合目录里对非归档对象宽容跳过。

See each object’s tier in its details, and move objects to Infrequent Access / Archive tiers to save cost — for a single object, a multi-selection, or a whole folder. Archived / cold objects can be restored before download, again for one object, a selection, or a folder (non-archived objects in a mixed folder are skipped gracefully).

对象与 Bucket 管理 | Object & Bucket Management

  • Content-Type 查看与编辑:详情里显示对象真实的 Content-Type(不再按文件名猜),可一键修改,修正传错的类型。
  • 新建 / 删除 Bucket:根层级「新建 Bucket」按钮,Bucket 右键「删除 Bucket」(需为空)。
  • 文件夹级递归:整个目录的下载 / 迁移 / 删除,保留相对结构,按文件数报进度。
  • 完整性校验:下载内容算 MD5 与远端 ETag 比对,一键确认文件未在传输中损坏。

Object details now show the real Content-Type (not a guess from the filename) and let you change it in place. Create a bucket from the root toolbar and delete an empty one from its context menu. Whole folders can be downloaded, migrated, or deleted recursively with structure preserved and per-file progress. Integrity verification hashes the downloaded bytes and compares against the remote ETag to confirm a file arrived intact.

  • 搜索过滤:递归搜索在按名字之外,新增最小大小与扩展名过滤——快速找出该归档的大文件。
  • 文件夹 / Bucket 统计:右键「统计信息」查看某个前缀下的对象数与总大小,下载 / 归档 / 删除前先心里有数。
  • Bucket 与文件夹区分:根层级的 Bucket 用独立图标显示,不再与普通文件夹混淆,右键也不再对整桶做危险的递归操作。

Recursive search adds min-size and extension filters on top of the name match, so you can quickly find the large files worth archiving. Right-click a folder or bucket for stats — object count and total size under a prefix — before you download, archive, or delete it. Buckets at the root are now shown with a distinct icon and no longer offer risky whole-bucket recursive actions.

界面 | Interface

  • 中英双语:界面从只有中文扩展为中英双语,在设置里一键切换,选择本地持久化。

The UI is now bilingual — switch between Chinese and English in Settings, with the choice persisted locally.
