| Abstract: | For the subjective or objective factors caused the loss of data on the computer,this paper proposed a child-brother tree-based deleted file recovery algorithm on Windows FAT32 file system. It introduced the structure of Windows FAT32 file system on disk and child-brother tree, an deeply expatiation that how to reconstruct the Windows FAT32 file system directory based on the child-brother tree, and how to quickly search and obtained the delete file directory table which could be used to recovery its related deleted FAT file by analyzing its value variety after removed was displayed by the paper as well as. |
