Can't overwrite an existing GIF file

[xan2622]

Hi.

I have imported a (5.2 Mb, a 11 seconds long video) .mp4 file into GIFTuna without any problem. But when I tried to export the video to a GIF file (overwriting a previous one on my disk), it just didn't work.

My previous GIF file is still in my folder (I use Windows 10 64 bits).
