Securely wipe the free space
BSEditor: This is a program which will securely wipe the free space on an ext2, ext3, ext4, NTFS, XFS, ReiserFSv3, ReiserFSv4, FAT12, FAT16 and FAT32 partition or drive, just like the shred program securely wipes files.

Requirements for compiling the full version:

* a non-root account. Please, NEVER compile or make anything as root.
* a working C compiler. XFS, ReiserFS and NTFS support require the long long data type.
* the make program
* development package for the C library (like glibc-devel and glibc-headers).
XFS support reuires the following headers: unistd.h, fcntl.h, mntent.h (but sys/wait.h, sched.h and paths.h can be useful, too) and the following functions: fork(), execvp(), dup2(), close(), pipe() and one of waitpid(), wait() or kill() (sleep() can be useful, too). Both ReiserFS require mntent.h to work (but will compile without it).
* Ext2/3/4: development package for the ext2 file system library, libext2fs (usually included in something like e2fsprogs-devel). If you dont have anything like this installed or available (check twice), then go to e2fsprogs.sf.net. Then compile and install that package. Ext4 support requires new versions, like 1.41.
* NTFS: development package for the NTFS file system library, libntfs (usually included in something like ntfsprogs-devel). If you dont have anything like this installed or available (check twice), then go to www.linux-ntfs.org. Then compile and install that package.
* XFS: xfsprogs installed and in your PATH variable, if you want XFS support.
* ReiserFSv3: development package for reiserfsprogs (header files and compiled Static *.a libraries from the package). ReiserFS requires the fork() function (unistd.h) and one of: waitpid(), wait() (sys/wait.h).
* Reiser4: development package for reiser4progs, libuuid (e2fsprogs or e2fsprogs-libs) and libaal. you can free download Wipe Free Space GUI 0.1 now.
