Enable access to files in long folder paths (longer than 255 characters)
AR is unable to open files where the file and folder path exceeds 255 characters. To accommodate this we have had to replace it with a competitor's software.

With Acrobat Reader version: 2023.003.20201 64-bit, I still encounter an error attempting to open pdf files with long path: "There was an error while opening the document. The path does not exist. ".
Other viewers, such as those built in browsers (Chrome, Edge) open the pdf file with a long path without any difficulties.
The path length limitation of 260 characters was removed from Windows starting W10 version 1607. Refer also to: https://learn.microsoft.com/en-us/windows/win32/fileio/maximum-file-path-limitation?tabs=registry#enable-long-paths-in-windows-10-version-1607-and-later
