The storage content method performs file carving to look for patterns in unallocated sectors in the hope that a continuous run of sectors will match a pattern. Typically, NTFS keeps a record of files, even those that have been deleted and this information is used to recover a (deleted) file. The file directory method retrieves information about the deleted file from the filesystem. This is, in part, because the files' data resides on the drive as fragments.ĮaseUS scans drives for deleted files in two different ways: (1) file directory and (2) storage content. (2019) showed that EaseUS can carve files from the LOST.DIR on an Android operating system. Consequently, file recovery software like EaseUS can, under some circumstances, recover deleted files from unallocated drive space. On most filesystems, file deletion typically does not erase the data itself but simply flags the file as having been deleted, and marks the physical space the file took up on the hard drive as empty, allowing other files to overwrite the deleted file.
