IsoBuster 3.2 Beta Released!

April 05, 2013

This beta version has been tested thoroughly and it is a release candidate. However, IsoBuster is not a simple program. It is not possible to test all aspects of the program on all types of media or image files. So, if you see something that doesn't work the way it should, let me know, that is the whole point of releasing a beta version after all. I really appreciate all feedback you can give

Here's a list of things I have been working on:


  • Support for ExFAT.
  • Find deleted NTFS files and folders during a scan for missing files and folders.
  • Implemented a "Find deleted files and folders" option, when an NTFS file-system is selected. This is a much faster scan if you're only interested in finding deleted files and folders in an NTFS file-system.
  • Support for FATX
  • Support for XISO / XDVDFS
  • Extended Master Boot Record (EMBR) support.
  • BSD partitions support.


  • Further improved the UAC experience by tweaking and fixing issues. The experience is still the same as described in previous release.
  • Remove duplicate partitions (for instance when there's a GPT but the MBR fields still point to valid partitions as well).
  • Ways to dump all sectors that are being read to log files (for debug purposes) (support for *.ibdat and *.ibadr).
  • Added .bkf file type recognition to the file-signature scan.
  • Further improved the ListView Columns' drag behaviour by working around (Builder) VCL limits/bugs.
  • An NTFS file also gets the Sparse property now when it's not fragmented (and not only when its extents are sparse)
  • Display the File's start LBA for a sparse file, except when the first extent is sparse, then "Sparse" is displayed
  • Added Full Path(s) and Start and Finish processing time to the MD5 file (as comments).
  • Ability (set via options) to store and restore the position of the main form (instead of always centered).
  • Added *.dd to the supported image files.
  • Recognize EXT SuperBlock when trying to determine the blocksize of an image (for instance a Linux made .dd file with an EXT1,2,3 or 4 file-system).
  • Improved handling of NTFS MFT embedded files during the scan for missing files based on their signature
  • Various other smaller GUI improvements


  • Not all *.png files were found during a scan for missing files and folders (bug introduced in version 3.1).
  • Mac HFS file systems with large fragmented files (more than 8 extents) could trigger a program crash.
  • In rare cases not all files and/or folders of an NTFS folder were found, if that folder was described in both the MFT record and via INDX records.
  • Sometimes too small files were created, when they were fully sparse (one extent, sparse (= all zeroes) (NTFS).
  • Fixed it so that the progress bar also changes color (red) in case of errors, during a scan for missing files and folders
