CRCDropper 3.4
Published
Shortly after I released version 3.3 of CRCDropper I realised that it wasn't working properly for very large files - I dragged my 17.3GB Ubuntu boot disk image onto CRCDropper and it told me the file was 1.32GB in size. This also meant that the progress bars stopped progressing long before the checksum had been calculated, though the hash value it eventually arrived at was correct.
Version 3.4 fixes this problem, and also adds a few more new features. The most obvious addition is the "Rescan all" button to compute hashes for all the files in the list again. If you don't want to keep all the files in the list, you can now press the "Delete" key to remove the selected item. Clicking on the selected item in the list will let you rename it (just the filename portion can be renamed, not the whole path to the file). This works like renaming a file in Explorer - press Return/Enter to accept the new name or Escape to cancel.
Another thing that didn't work very well in earlier versions was what happened when you dropped a folder on CRCDropper - it was treated as an empty file. That's pretty useless, so version 3.4 will find all the files in the folders that you drop onto it and any subfolders, and add them to the list. It will skip over any folders it finds that begin with a "." but you can drag and drop them separately if you need to.
I've added another algorithm to the drop-down list to support RIPEMD-160, and I've made some more updates to the dialog to make it redraw better when being resized.
The image above (rendered with Blender) is what I was thinking of using as the full-colour icon for Vista and Windows 7 (Windows XP users would still see the current 16-colour icon).
Unfortunately, using it increased the size of the executable file to 212KB. I've always tried to keep the size of CRCDropper down to a minimum, so making the program 30% bigger just to add a more colourful icon didn't seem worth it to me. These big full-colour icons are actually stored as PNG images inside the program file - if it had been uncompressed, just the image would be bigger than the CRCDropper 3.4 .exe file.
