Why are my old cell phone videos coming up as .plt format files on my Android tablet?

Question

Videos I've saved from my old cell phones are coming up as .plt and .blt file formats. They used to be 3g2 format playable as a .mov on QuickTime. I never converted them to anything else but for some reason they are now in these formats.

If I prompt the tablet to open the .blt files as images, I get a thumbnail for the associated video. The same cannot be said when I prompt the tablet to open the .plt file as a video. It simply tells me the video cannot be played.

In my opinion, there is a big misunderstanding. I have performed search queries on Google using the provided file types you have mentioned and it seems that those file types belong to applications outside the video/audio category. More precisely, they are used by CAD applications. Please double check again for the files you have copied because even a conversion to transform the files from 3g2 to blt/flt isn’t possible.
