  • Bugfixing: missing directory icons and slow performance after repeated search.
Version 7.0.4 from 2020 September 21
  • Fixed GDI+ exceptions caused application to crash after large amount of files were scanned. The GDI+ errors caused by Windows limitations on the number of file icons which can be created in memory simultaneously.

  • Added Spain (Colombia) language translation (thanks to Carlos Andrés Medina Rivera!).
Version 7.0.3 from 2020 September 08

  • Fixed: the logging for completed file operations was broken.
Version 7.0.1 from 2020 September 06

Version 7.0 from 2020 July 27
  • Added support searching for audio, video and image (only .jpg) files with the same binary media content but different metadata and media tags.

  • Drive letters (volumes) are grouped in folder tree by physical drives which they belong to.
  • Added support for hard links and symbolic links in EXT2/EXT3/EXT4 file systems (I've tested it only with Ext2Fsd-driver for Windows https://www.ext2fsd.com/ ).
  • Implemented search for duplicates in ZIP-archives. In order to search in ZIP-archive it should be added under "Archive" node in the folder
  • tree. File operations with files in ZIP-archive (rename, delete etc) are not supported.

  • Added possibility to move files including folder structure.
  • Several small fixes and improvements.
  • Windows XP: this version was build for .NET Framework 4.7.2 and above, which has more features and better performance, but it doesn't support Windows XP.
