Description

  • Request:
    Provide an option to set a string, which is used as a prefix when obscuring file names (e.g. on erasing unused space). Default should be empty, so there's no change to Eraser's current behaviour.
  • Reason:
    If files got deleted by accident (not erased), then it is hard to find the real files inside the list with all these random file names. A constant prefix will help tremendously as all obscured file names are en-block. Finding the real files will be much easier, independent of the tool you (have to) use.
  • Topic "plausible deniability":
    When this new option is empty, which should be the default setting, then there is no difference to Eraser's current behaviour. If the user decides to use a constant prefix for file name obscuration, then it is the user's choice.
    Also most users do not need plausible deniability, they just need to be sure that no one else can...
    a) recover erased files with private or company data
    b) drew conclusions from the real file names
    Even with a constant prefix these points are still reached.
  • Example without a prefix, just like current Eraser:
    .LMrRJGXMdZwX-mV
    5pzEK_PgQoN5.qBU
    6dollar_bill.txt
    D3wbfhskDWVkDE5c
    hoYY3soXeDGgSP5M
    iamarealfile.xls
    iePwP_WnLPF9AsLm
    jU93Fo3Xm4W-N2dD
    makefile_old.bak
    MAmVp2xJ9ue4kDFD
    wgaLNzsCNmJ5BZ6Y
    ypsilon-letter
    zLpX3ymW8E_rjhMF
    
  • Example with a user-defined prefix of "zY6b":
    6dollar_bill.txt
    iamarealfile.xls
    makefile_old.bak
    ypsilon-letter
    zY6b.LMrRJGXMdZw
    zY6b5pzEK_PgQoN5
    zY6bD3wbfhskDWVk
    zY6bhoYY3soXeDGg
    zY6biePwP_WnLPF9
    zY6bjU93Fo3Xm4W-
    zY6bMAmVp2xJ9ue4
    zY6bwgaLNzsCNmJ5
    zY6bzLpX3ymW8E_r
    
    You see the prefix makes it much easier to find deleted files after the last erase of unused space.
  • Situation where this option would have been useful for me:
    • Erased unused space with Eraser, so all unused file entries got obscured file names (I do this twice a year).
    • Worked with the system for a longer time.
    • Accidentally deleted some files (not erased).
      There were 12.000 deleted files on my hard disk (which is for working/downloads/temp) and I knew that around 1000 files got deleted by accident.
      I didn't know all the names of the 1000 files, so I had to check each and every entry of the list if it could be a file that I accidentally deleted.
