Adobe password.
A master file carrying a huge amount of text data was/is in a pdf file. After years I tried to open it and it's asking me for a password.
I have no recollection of Adobe having a password mechanism, and if it did, I didn't use it, of that I'm sure.
Anything I can do? I do have the data in a more simplistic form, but I've a feeling the pdf would have been the most up to date offering.
