FillDisk v0.02

billon on 28 Mar 2018
  • 801KB (uncompressed)
  • Released on 3 Aug 2008
  • Suggested by donald

FillDisk is a simple utility that fills up a disk with data. This is useful for testing a separate application's behavior when a disk is approaching full capacity or basic free space shredding when you don't have admin access (recommend checking "No OS optimization"). The program starts with 1GB files, then drops to 512MB, 256MB and so on until it completely fills up the disk.

FillDisk has a very simple interface: just enter a folder for the files to be created and press the "Go" button. You can stop the operation at any point in time and the file that is currently being written will close.

download-buttons don't work. On https://www.portablefreeware.com/index.php?sc=217 the download-button gets the wrong programme (one from nirsoft).

Eraser v5.8.8

webfork on 16 May 2015
  • 2MB (uncompressed)
  • Released on
  • Suggested by MISIIM

Eraser is a feature-rich tool to permanently delete sensitive data from your hard drive by overwriting it with random patterns. Includes a scheduler, free-space wipe, random number generation for better overwriting, page file wipe at shutdown, password-protected settings, and more. The program includes a wide variety of wiping mechanisms from very fast (only deleting the first and last 2kb) to extraordinarily slow (35-pass). Note that all but the most security-minded users should only need only the 1-pass "pseudo-random" wipe.

Alternatively, Eraser Portable is a PortableApps version.

Note: The 5.x branch is no longer supported. There is a 6.x branch available, but there is no official portable version for this branch and it requires the .NET framework.

What's new? Do not erase sparse, compressed or encrypted files when FL2KB erasure is selected to prevent disk corruption.
Fix Win32 Eraser builds to be truly Unicode builds.
A few 64-bit fixes.
Ensure that Eraser uses the latest runtimes packaged with the installer. This should fix hangs when using the Context menu.
Fixed the About dialog after migrating to Unicode
Sign all binaries packaged with the installer
Allow erasing UNC paths
Fixed memory exhaustion when doing a free space erase for FAT drives
Migrate non-Unicode custom erasure methods to the Unicode methods so that old custom erasure methods are preserved upon upgrade

Ensure that Eraser is not running when the Eraser setup is run

Peter: Yeah we've got something in the entry about that.

Eraser 5.8.8 Portable does not integrate to Windows shell on x64 systems (in my case- Windows 8 x64).

DP Shredder v1.5

webfork on 22 Sep 2016
  • 198KB (uncompressed)
  • Released on 30 Dec 2008
  • Suggested by Andrew Lee

DP Shredder erases files/folders securely and wipes disk free space using one of the following methods: zero, pseudo-random data, RCMP (DSX), US DoD 5220.22-M (E), US DoD 5220.22-M (ECE) or Gutmann 35x.

Multiple wipe actions are progressively slower. All but the most security-minded users should only need a pseudo-random overwrite.

The author "Dirk Paehl" has an interesting collection of software, I'm not sure if they are all portable though.

roddersg on 2009-08-17 02:41

What I don't like about this program is there the indication that it is running is just the "Pass N" on the bottom bar and the "waiting" icon on the application. A progress bar would be much better.
As for doing its job, the data space looks pretty much randomised and I can't see my old data.

This program only deletes Gutman procedure. Will NOT move from that option. Recently categorised as MAlware site by Forticlient

CyberShredder v1.12

webfork on 20 Dec 2016
  • 490KB (uncompressed)
  • Released on 20 Sep 2008
  • Suggested by M. Maltbia

CyberShredder is an easy to use, drag-and-drop way to delete files and folders from your computer permanently. While normal file deletion remove a file's directory entry and allocation table information, the actual disk clusters that contained the file's data remains intact on your hard disk and can be recovered. CyberShredder overwrites the space occupied from a file with random data and then erases the file, so recovery tools cannot recover it.

Although the "very quick" shred should be more than adequate for most users, there are multi-pass methods available that overwrite the file multiple times.

Warning: Some users have reported issues when wiping directories with non-English characters in them.

What's new?
  • Quicker abort, abandons operation even at the end of a file operation.
  • File operation progress gauge, shows progress of each file operation (pass).
  • Renames file multiple (26) times, not just once.
  • Remembers form position.

A possible portable alternative (untested!) is Quick Erase -- see http://www.softpedia.com/get/Security/Secure-cleaning/Quick-Erase.shtml.

@webfork. Sorry, only just saw this post. I don`t have a copy of that folder anymore as I`ve moved to a new laptop. Sorry.

Herki on 2014-06-18 12:57

I had precisely the same issue as hamasaki above - tried to drag and drop a folder that contained asian characters in its name and, to my horror, found Cybershredder began a rampage through a completely unrelated area of my hard drive.

From what I can tell, and this tallies with hamasaki's experience *if* he had placed the cybershredder.exe in 'program files', the glitch redirects the shred request to contents of the the folder one level above the folder in which cybershredder.exe is placed.

No idea why this happens, but be warned!

Disk Redactor v1.2

  • Suggested by AlephX

Disk Redactor erases all free space on any hard disk or flash memory storage, preventing deleted files from being recovered.

Note: Disk Redactor does not scramble the filenames, so they can still be read by recovering applications, even if the file content is wiped out.

Would the lack of filename scrambling fool a recovery tool into classing the file as in good condition?

I've run this several times over my drives and Recuva, Undelete plus, Restoration and Pc inspector file recovery are all picking up thousands of "deleted" files in good/excellent condition

Disappointed on 2008-09-28 03:12

No longer portable.
The ini file for the settings is stored in the application data folder
