File remains open behind the scene even when tab closed
This is a recurring problem with Adobe Acrobat Pro DC: When a file is closed in Acrobat (by closing the corresponding tab), the program doesn't not release the file. As a result, the file cannot be renamed or moved until Adobe Acrobat Pro DC is closed. I have attached an image of the error dialog that pops up. This is on Windows.
Of course, this is a major inconvenience because I have many tabs open and closing Adobe merely to be able to rename a file that's no longer supposed to be open in Adobe is not something that enhances my productivity. (Especially that Adobe doesn't appear to offer a way to restore tabs when the program is exited.)
The error here explains that the PDF is opened in Adobe PRO.
This could be because the file is still writing the changes made in the PDF.
Could be that the file is opened from a server location/shared servers. And that the change is waiting to commit.
