Temporary working files in the source directory?
That is going to cause problems when the source file is on a slow drive, a space-constrained drive, a read-only drive, or simply a drive that is not the output destination drive.
In the case of having source and destination files on different drives, does that now add a time-consuming drive-to-drive copy when converting temporary to final (rather than an instantaneous in-place rename)?
Also, there are established places for storing temporary files (eg: %TEMP%) which avoids cluttering user project space and makes cleanup easier when things go wrong or are abandoned while incomplete.
EDIT: I went to extract the old icon to customize the Start Menu shortcut to escape the green glow and discovered the embedded icon is non-standard to the point that icon editors have trouble opening it: 1044, 522, 266, 100, 68, 50, 42, 34x33, 26x25, 18x17 (not 1024, 512, 256, 128, 64, 48, 32, 24, 16 square). If the OS ends up having to rescale the icons, they won’t be as crisp.
