Today I went to somebody with a PDF file, I've made it with LibreOffice Writer, but, when he tried to open the file, it said that it was a corrupt file, my PDF.
I've put the file on my usb stick, and from there he opened it.
What can I do to open that file on that pc? I have to say that other files (PDF) can be opened on that pc. My file can't be corrupt because some of my friends can open it.
