A. PhotoRec, Digital Picture and File Recovery
PhotoRec is file data recovery software designed to recover lost files including video, documents and archives from Hard Disks and CDRom and lost pictures (thus, its ‘Photo Recovery’ name) from digital camera memory. PhotoRec ignores the filesystem and goes after the underlying data, so it will still work even if your media’s filesystem has been severely damaged or re-formatted.
PhotoRec is free, this open source multi-platform application is distributed under GNU Public License. PhotoRec is a companion program to TestDisk, an app for recovering lost partitions on a wide variety of filesystems and making non-bootable disks bootable again. You can download them from this link.
For more safety, PhotoRec uses read-only access to handle the drive or memory support you are about to recover lost data from. Important: As soon as a pic or file is accidentally deleted, or you discover any missing, do NOT save any more pics or files to that memory device or hard disk drive; otherwise you may overwrite your lost data. This means that even using PhotoRec, you must not choose to write the recovered files to the same partition they were stored on.
Operating systems
PhotoRec runs under:
* DOS/Win9x
* Windows NT 4/2000/XP/2003/Vista
* Linux
* FreeBSD, NetBSD, OpenBSD
* Sun Solaris
* Mac OS X
and can be compiled on almost every Unix system. Read the rest of this entry »
Sebagai pengenalan, perisian sumber terbuka yang yang perlu diberi perhatian adalah 7-zip. 7-zip dipaten di bawah lesen GPL. 7-zip secara umumnya boleh dikategorikan sebagai “file archiver”. Ia berfungsi untuk menyimpan seberapa banyak file ke dalam satu file dalam format 7z.
