I am sorry, but I am not able to get you. Are you experiencing any issue related to Adobe Acrobat/Reader?
And we don't even know if you are in Mac or Win...
hai ragione, scusatemi.
si tratta dell'app ADOBE ACROBAT par IPAD!!!

Still, in what way does this relate to Acrobat or Reader?

You need to connect your iPad to a Mac or PC and use file browser software for your computer OS to rename the missing file on your iPad.
Adding a period (.) before a name makes it invisible.
A file or folder name starting with '.' ("dot" or "period") is considered hidden on most operating systems. By naming a file starting with '.', you accidentally hid the file and made it inaccessible to all iOS apps.
I'd highly recommend using '_' ("underscore") in the future.
We have already made the change to the new Acrobat Reader for iOS app (version 15.0.x) so that it disallows the rename operation with '.' as the first character. (I assume that you are using Adobe Reader for iOS on iOS 7 or older iOS version.)
To recover your hidden file, you need to use a Windows or Mac desktop/laptop computer, install a special File Manager app (e.g. iExplorer free demo mode, iFunBox - not Windows Explorer nor Finder), connect your iPad, browse the file system on your iPad, and rename the file back to something else (so that it becomes "visible" again).
The exact steps vary depending on the special File Manager app you choose. You may be able to find How-To videos on the software manufacturer's web site or YouTube.
