Dear all,
on my Onyx Boox M92 (from ArtaTech) I have the problem that PDFs are always displayed in the file manager with the PDF title instead of the file name. Often the PDF title is absolutely useless, such as "Untitled.doc" whereas the file name is easy to change and is for my files Author-Year_Title.pdf.
On my device there is no option to enable the file name view like some here have reported (I don't know why, because the firmware is 2012-07-25).
To solve the issue, I wrote a small script for Linux which writes the file name directly into the PDF title metadata (for all files in a selected folder). I assume that it might be helpful for some of you.
