I was muxing a .ts file with the use of tsmuxer gui but when all was done, i opened the file location of where the file should have went and it was not there. I then tried to search my computer for the name i would have saved it under and the file type it would have been, but there are no files that match what should have turned up. But i know that the file is somewhere because i lost 40gig of my hard drive because thats how much it should take up. If anyone thinks or knows the solution to this problem, please reply.
