Bit of a silly mistake here...
I was on Inkscape, made a *.SVG and went to save it. Now, I went to overwrite a *.GIF file and I saved it as a *.GIF file. So now I have a SVG saved as a GIF in the folder with all my photography.
I'm assuming the file is being read wrong and/or it can't generate a thumbnail. But I open it, go to rename it and then it freezes. Sometimes the whole pc freezes, but not always.
Any help would be appreciated, John.
