Computer Data Migration | Easiest Way to Transfer Data from Old PC to New PC

1/22 Edited to

... Read more私がPC引っ越しで一番困ったのは、「USBでコピーすればOK」と思っていたら、移せるのが“ファイル”中心だったことです。写真・動画・Word/Excelは移せても、アプリ本体やログイン情報、細かい設定は別物。新しいWindows PCで同じ環境を早く再現したい人ほど、最初に“どこまで移したいか”を決めるのが近道でした。 まず結論から言うと、データ移行は大きく3パターンあります。 1) USB/外付けSSDでファイルをコピー:一番簡単。ただしアプリや設定は基本的に移らない。 2) クラウド(OneDrive/Google Drive等):複数端末で同期できて便利。容量次第で有料になることも。 3) ストレージを「丸ごと」移行(クローン/イメージ):環境をそのまま持っていきたい人向け。失敗しにくい反面、手順を間違えると起動しないこともあるので慎重に。 私がやってよかったのは、最初にチェックリストを作ることでした。 ・移したいもの:ドキュメント、写真、デスクトップ、ダウンロード、メール(Outlook等)、ブラウザのブックマーク/パスワード ・再インストールが必要なもの:Office、Adobe系、プリンタドライバ、チャットツールなど ・見落としがちな場所:C:\Users\(ユーザー名)配下、アプリのデータ(AppData)、NAS/外付けに置いたフォルダ 「丸ごと移行」を考える場合は、移行前に必ずバックアップを取り、BitLocker(ドライブ暗号化)がONなら回復キーを控えておくのがおすすめです。新PC側のストレージ容量が足りないと移行できないこともあるので、古いPCの使用容量を確認してから動くと安心でした。記事内で触れられているAOMEI Clonerのようなクローン系ツールを使うなら、“どのディスクをコピーするのか(コピー元/コピー先)”を必ず見直して、接続している外付けドライブを間違えて消さないよう注意しました。 ちなみに「リモートデスクトップでファイル転送したい、容量が大きいけど大丈夫?」という場合、RDPの転送は便利でも大容量だと遅かったり不安定になりやすい印象でした。数十GB以上なら、外付けSSD(USB3.0以上)やLANでの直接転送の方が体感で速く、途中で止まるストレスも少なかったです。 最後に、移行後の確認も大事です。新PCで主要フォルダが開けるか、写真が欠けていないか、Outlookの送受信ができるか、プリンタが印刷できるかを一通りチェック。ここまでやっておくと、PCデータ移行の「あとから困る」をかなり減らせました。
