削除されたデータの復元：紛失したファイルを復元する究極のガイド
Accidentally deleting an important document, photo, video, or work file can be stressful, especially after you empty the Recycle Bin or use Shift+Delete. Fortunately, 削除されたデータの復元 may still be possible if the original data has not been overwritten. The safest approach is to stop using the affected drive, check built-in recovery options first, and then use a suitable 削除ファイル復元 tool when necessary.
このガイドでは、以下の方法について説明します。 削除されたデータの復元 works, what to do immediately after deletion, which recovery methods are worth trying, and when Magic Data Recovery can provide a simpler solution for Windows users. You will also learn how recovery differs between HDDs and SSDs, which mistakes to avoid, and what factors affect your chances of recovering lost files.

何であるか Deleted Data Recovery and Can Deleted Files Be Recovered?
削除されたデータの復元 is the process of restoring files that are no longer accessible through normal file browsing.
In many situations, deleting a file does not immediately erase every part of its data. Instead, the ファイルシステム marks the storage space as available for reuse. Until new data overwrites that space, a recovery tool may still locate the file record or identify recoverable content.
However, no recovery method can guarantee success. The result depends on several factors, including:
- ファイルの削除方法
- Whether the device was used afterward
- ストレージ・デバイスのタイプ
- ファイルシステム
- Whether the data has been overwritten
- Whether an SSD has processed TRIM
- ドライブに物理的な損傷があるかどうか
Therefore, the sooner you take the correct action, the better the recovery conditions may be.
Where Does Deleted Data Go?
On an HDD, USBドライブ, あるいは SDカード, deleted content can remain on the storage medium until new information overwrites the same area.
アン SSD works differently. Modern SSDs may support トリム. This feature lets the operating system tell the SSD which blocks are no longer needed. The SSD may later erase those blocks internally during garbage collection.
As a result, recovering deleted files from a TRIM-enabled SSD can be more difficult than recovering them from a traditional HDD.
What to Do Before Starting Deleted Data Recovery
Your first actions after losing a file can significantly affect the result.
1.影響を受けたドライブの使用を停止する
Do not download files, install applications, copy data, or create new documents on the same storage device.
Every new write operation creates a risk that Windows will reuse space previously occupied by the deleted file.
2. Do Not Install Recovery Software on the Source Drive
Suppose you deleted important files from drive C:. Installing recovery software directly onto that same physical drive may overwrite data you want to restore.
Whenever possible, use another physical drive or external storage device.
3. Save Recovered Files to Another Location
Do not recover files back to their original drive during the first recovery attempt.
Instead, save them to another HDD, SSD, USB drive, or other safe destination. This prevents recovered data from overwriting files that have not yet been restored.
Following these basic rules creates safer conditions for 削除されたデータの復元.
How to Recover Deleted Data: 5 Practical Methods
The best solution depends on how the files disappeared. Start with the simplest method before using a deeper recovery scan.
Method 1: Restore Deleted Files from the ごみ箱
If you deleted a file normally in Windows, check the ごみ箱 第一に.
- ごみ箱を開く。.
- Find the deleted file or folder.
- アイテムを右クリックします。.
- 選択 リストア.
Windows will return the file to its original location.
This is usually the safest and fastest solution when the file has not been permanently removed.
Method 2: Recover Deleted Data from a Backup
If the file is not in the Recycle Bin, check any available backups.
考えられる情報源としては、次のようなものがあります：
- Windowsのファイル履歴
- クラウドストレージ
- External-drive backups
- バックアップソフト
- Manually copied files
For example, imagine that you accidentally deleted an important project folder this morning. If your backup contains a copy from the previous evening, restoring that version is usually safer than scanning an entire disk.
A valid backup should generally be your first choice because it restores an existing copy rather than attempting to reconstruct deleted information.
Method 3: Try Windowsファイル復元
マイクロソフトが提供する Windowsファイル復元 as a free command-line tool for recovering deleted files that are no longer in the Recycle Bin.
使用方法：
- インストール Windowsファイル復元 をマイクロソフトストアから購入する。.
- Connect another drive to save recovered files.
- Open the tool and enter a command such as:
winfr C: E: /regular /n *.docx - プレス
Yto start the scan and check the recovery folder on drive E:.
用途 Regular mode for recently deleted files on NTFS drives. If it cannot find the files, try Extensive mode for a deeper scan.
Because the source and destination drives must be different and the tool requires command-line input, beginners may find a graphical 削除されたデータの復元 tool such as Magic Data Recovery easier to use.
方法4：使用する データ 復旧ソフト
When the Recycle Bin and backups cannot solve the problem, dedicated データ復旧ソフト can scan the affected storage device for recoverable content.
This approach is particularly useful after:
- Shift+削除
- ごみ箱を空にする
- Accidental folder deletion
- Deleting files from an external HDD
- USBフラッシュドライブからファイルを紛失する
- Deleting photos from an SD card
- Certain quick-format situations
A graphical recovery application can simplify 削除されたデータの復元 because you can select a drive, scan it, review the results, preview files, and choose what to restore without entering recovery commands manually.
Method 5: Use a Professional Data Recovery Service
Software is not suitable for every data-loss situation.
Stop using the drive and consider a professional service if:
- The HDD makes clicking or unusual mechanical noises
- The device repeatedly disconnects
- Windows cannot detect the drive reliably
- The storage device has suffered water, impact, or electrical damage
- The lost information is business-critical and cannot be risked
Repeated software scans are not a good idea when hardware is physically failing.

Deleted Data Recovery on HDD vs SSD
Storage technology plays an important role in whether deleted information remains recoverable.
Recovering Deleted Data from an HDD
Traditional hard drives often provide better recovery conditions after accidental deletion.
When Windows deletes a file, the corresponding data may remain on the disk until new information overwrites those sectors.
Therefore, an accidentally deleted file from an HDD may still be recoverable if you stop using the drive quickly.
Continued downloads, software installations, Windows updates, and file transfers can reduce that opportunity.
Recovering Deleted Data from an SSD
SSDリカバリー is less predictable.
Many modern SSDs support TRIM and internal garbage collection. After deletion, the operating system may tell the SSD that certain blocks are no longer required. The SSD can then process those blocks internally.
Once the original data is no longer accessible, standard recovery software may not be able to restore it.
For this reason, immediately reduce drive activity if you need to recover important files from an SSD.
共通 Deleted Data Recovery Mistakes to Avoid
Even good recovery software cannot undo every mistake made after deletion.
以下は避けること：
- Installing recovery software on the affected physical drive
- Recovering files to the same source device
- Continuing to download or copy files
- ドライブを再度フォーマットする
- Repeatedly scanning a physically failing disk
- Assuming that a visible file name means the file itself is intact
- Continuing to use an SD card after deleting important photos
A safer strategy is simple: stop writing new data, choose the correct recovery method, preview files when possible, and save recovered content elsewhere.
まとめ
成功 削除されたデータの復元 starts with one important rule: stop writing new information to the affected storage device.
Next, check the Recycle Bin and available backups. Use Windows recovery options when they fit the situation. If you need a deeper scan, file preview, or a simpler graphical workflow, dedicated recovery software becomes a more practical choice.
Magic Data Recovery is worth considering for ordinary Windows users because it provides a clear process for selecting a device, scanning for deleted files, reviewing results, previewing recoverable content, and saving selected data to another location. It does not remove the technical limits of data recovery, and it cannot guarantee files that have already been overwritten. However, its visual workflow can make the 削除ファイル復元 process easier to understand and help users avoid common command-line mistakes.
If you are looking for a more efficient solution after accidental deletion, Shift+Delete, an emptied Recycle Bin, or file loss from removable storage, consider trying Magic Data Recovery.
