I borrow one Samsung chromebook from my friend about two weeks ago. I remember there are some MS ppt files on it. But now i can not find them(I have search all the disk). I think they are lost with my misoperation. Can i recovery lost files from chromebook for about two weeks?
Chromebook is just the generally referred to chrome os. So many manufacturers have chromebook. Such Samsung, Acer, HP, etc. So i think if the chromebook have normal hard disk, we could install data recovery software(.exe)on it. If the hypothesis can be set up, you can try do your data recovery , minitool or rstudio on it to try.
