This question already has an answer here:
I have downloaded this pdf file with a very long name, which cannot be opened by Adobe Reader or by Adobe Professional because it has "invalid file name".
It cannot be renamed using the DOS prompt but it has "too long name or extension". I tried to delete so that my recovery program can rename then restore it, it but it won't be deleted as a file.
The only way to delete it is by deleting the folder where it was downloaded into (which I did, but restored it later). It can't also be printed or moved or copied to another folder. Is there a way to open or rename these kinds of files?
I tried to rename it by right clicking the title but what appears is a shortened version of the options with no rename function. I then discovered that it has a password protection, which is not provided by the website from which I downloaded it.
