Unable to close files in Acrobat
I have been viewing a number of saved pdfs (journal articles) in an attempt to reorganise my files. I now have a problem that if I open a file I then am unable to close it. I close it on Acrobat and indeed close the whole programme down but the file remains on there and I cannot rename it or move it to a more suitable folder in file explorer (Windows 10). It is completely blocked by the system which tells me that it is still open.
I have tried reloading Acrobat but my version is up-to-date and I cannot download a more up-to-date version.
This is making life very difficult. Can anyone help?
Thanks
