同步媒体文件Sync Bin

同步媒体文件（Resync Media Files）让媒体夹与硬盘上对应的源文件夹保持一致——文件夹里来了新素材，媒体夹跟着补上。

• 前提是按文件夹导入：只有当初用"文件夹生成媒体夹"方式导入的媒体夹，才知道自己对应哪个源文件夹。
• 手动同步：右键媒体夹选 Resync Media Files，自上次导入后新增的文件立刻补进来。
• 自动同步：右键勾选 Automatically Resync Media Files，之后新文件自动进媒体夹，全程不用动手。
• 只补新、不打扰：同步只往媒体夹里加新片段，已整理好的片段和时间线原样不动。
• 典型场景：拍摄期素材每天回传进同一个文件夹、多机位素材陆续到齐——同步替你省掉反复手动导入。

Resync Media Files keeps a bin in step with its matching source folder on the drive — when new media lands in the folder, the bin catches up.

• Requires folder-based import: only a bin that was originally created by importing a folder knows which source folder it belongs to.
• Manual sync: right-click the bin and choose Resync Media Files; files added since the last import appear immediately.
• Automatic sync: right-click and enable Automatically Resync Media Files; from then on new files flow into the bin by themselves.
• Adds only, never disturbs: syncing only adds new clips to the bin — your organized clips and timelines stay untouched.
• Where it shines: footage arriving daily into one folder during a shoot, or multi-camera material trickling in — syncing saves you repeated manual imports.
