Updated to get the new email contact information and latest internal code changes
This release is largely an overhaul of the code to bring it more up-to-date using modern C++ language and library features that have consequently simplified the code. Overall, there are only minimal changes for registered users. However, we have removed all unregistered limitations so it is now free to everyone and the source code is available on GitHub if you want to have a look at it.
Minor update to fix slow starting of Windows Explorer when Explorer is invoked in some situations (such as when using WinKey+E).
Added x64 version.
Changed documentation to HTML.
Allow '&' character in the registration name field.
Windows Vista compatible.
Registration is now per-user rather than per-machine so as to work under Vista without requiring elevation.
You will need to reenter your registration details if you upgrade from an earlier version.
Handle splitting to files > 4GB. Note that only NTFS formatted disks (NT4,
Windows 2000, Windows XP, and later operating systems) supports files greater
New fixed size options for extended CD & DVD sizes.
Internal coding improvements to reduce memory usage with large selections.
Fix for minor cosmetic problem when the Split dialog is initially shown without the "to" file name(s).
Registry setting option to not display the context menu bitmap.
Use new registration number scheme.
Delete split files if the split operation is cancelled.
Minor change to display the regionalised About dialog from the Split dialog rather than the embedded English version.
Changes to allow language translation by having all resources in a separate
Fix for a specific situation where a system error was misreported.
Added more precise error message if the destination file couldn't be opened during the Split operation.
Split dialog has more preset media sizes (for memory cards and CDs) and a
"removable" media option that scans all removable drives and presents the
available space on each. Custom sizes are still catered for by entering the
figure in the combo box edit field. Very old (small) floppy preset sizes have been removed.
Split & ConCat operations are multi-threaded - the UI stays responsive and redraws while performing the file operations, and the operations can be cancelled.
Supports Unicode. Windows 9x & ME operating systems aren't fully Unicode, so support under those operating systems is limited.
Setup now uses the MS Windows installer.
Dialog Cancel buttons are now labeled Close except when the Split or Concatenate operations are working.
Fixed a potential problem where the ConCat "To" destination file is in use when the ConCat operation starts. It would have resulted in being unable to rename the temporary destination file to the original name.
Revised several error messages and improved error reporting by displaying the underlying Windows system error message.
Added auto-complete to the Concatenate "To" edit control.
Code changes ready for Unicode version.
Corrected potential problem in initialisation of split dialog.
Fixed a bug that caused a crash if low disk space occurred when concatenating
Modified the ConCat list display to ensure that the right hand side is normally visible since the numerical file extension is the most relevant part of the name to see. Similar for the display of the current file name that's being concatenated.
In a registered version, the ConCat list is now automatically sorted.
Enhanced the code used in a registered version to remove the digits to form the original file name.
Changes to the concatenate dialog to display the file part number, and to
just show the filename (rather than the full path) in the progress section.
The concatenate file overwrite prompt now displays the file name.
Correction to support numerical output of file sizes in locales that use Indic grouping of numbers (e.g. 12,34,45,789).
Added progress displays to the dialogs to give feedback when manipulating
Added support for files greater than 4GB. Note that only NTFS formatted disks (NT4, Windows 2000, Windows XP, and later operating systems) supports files greater than 4GB.
The file names in the copy batch file now have surrounding quotes to work
with file names that have spaces in them.
Added the option to overwrite any existing files in the split operation.
Fixed a 2GB problem in the split dialog operation. Files > 2GB can now be split and rejoined correctly.
Registered version saves the last used split size.
Display the original file size value in regional number format.
Disabled the Change button for the batch file creation in an unregistered version.
Removed the "success" dialog boxes. Confirmation is now done with a beep instead. Failure will still display suitable error messages.
Modified the About dialog. Changed the registration number field to make it a little easier to enter the number. Updated the home page URL and added a mail link.
Modified file handling (yet again). The previous method had problems splitting files > 800 MB under Windows 9x, and even Windows NT could not cater for manipulating files where the total size approached 2GB. This version can now split and join very large files under both Windows 9x and NT.
Modified to handle very large files.
Minor change to allow international registration names.
Modified the file handling operations to allow manipulation of very large files (several hundred MB).
Rebuilt, and updated documentation for the new self extracting installer.
Added cosmetic bitmaps for the menu items to aid visibility.
New registration system.
Improved presentation of long items in the ConCat dialog list box - uses the familiar ellipses notation for long paths.
