Recuva is a data recovery program that uses advanced algorithms to scan and recover lost or deleted files from your computer or storage device. In this article, we will explore the technical aspects of how Recuva works.
File System Analysis
Recuva performs file system analysis to locate deleted files. The program scans the file system's master file table (MFT) and other system records to find information about the deleted files. Recuva also scans the free space on the storage device to find fragments of the deleted files.
Signature Search
Recuva uses signature search to find files that are not listed in the file system records. The program looks for unique file signatures, such as the file header and footer, to identify the deleted files. This method is useful when the file system records have been damaged or overwritten.
Quick and Deep Scans
Recuva offers two types of scans - a quick scan and a deep scan. The quick scan is faster but may not be able to find all of the lost files, while the deep scan takes longer but can find more files. The quick scan searches for files that have been recently deleted or emptied from the recycle bin, while the deep scan searches for files that have been deleted a long time ago or have been overwritten.
Preview and Recovery
Recuva allows you to preview the recovered files before you save them. This can help you determine whether the files are intact and worth saving. When you recover files using Recuva, make sure to save them to a different location than the original storage device. This will prevent overwriting and further damage to the lost files.
Compatibility and Customization
Recuva is compatible with all versions of Windows and supports a wide range of file formats. The program also allows you to customize the search criteria, such as file type, size, and date modified. This can help you narrow down the search results and find the files you need more quickly.
In conclusion, Recuva is a powerful data recovery program that uses advanced algorithms to scan and recover lost or deleted files from your computer or storage device. By using a combination of file system analysis, signature search, quick and deep scans, and preview and recovery options, Recuva can help you recover your lost data quickly and easily.
