Grey X

[LeanneBluebird]

Why is this grey X appearing on all my older PDF documents?

I am unable to open (or open with) any of these documents.  I click and nothing happens.  Help!  I need access to these documents

[Bernd Alheit]

Try this:

• start/open Adobe Acrobat
• use the menu File > Open...

Thanks.  No.  that doesn't work.#

Can you copy the files?

[Nesa Nurani]

Are those files connected to Dropbox?

Is your HDD getting out of space?

Try copy them somwhere else (Don't move them, copy them).

Thanks all.  Turned out that my One Drive wasn't syncing.  All sorted.
