ReNum
ReNum 2.1 by Emil Åström - A utility that changes the names of sequences of files. ReNum is aimed at helping animators that wish to transfer files, say from Real3d to DPaint. Real3d calls IFF-files generated as an anim something like this: Pic0, Pic1, ..., while DPaint wants multiple IFF-files to build an animation, to be in alpha order.
