Acrobar Reader DC is still not capable to open files with paths longer than 255 chars. This is a serious problem, and it's not a problem of the OS (Windows 10/2016 support long paths). The problem in details have been described in these topics:
Is there any plans to solve this problem?
I don't know if anyone has reported it yet. I suggest you do, and please post back the URL here. That allows others affected by the problem to add more votes, so it might get fixed if the problem is popular enough.
Test Screen Name, thanks for your suggestion. I submitted bug report, but after submit there was no link. So I can't post link here and I don't know how to find my bug report again.
I will gather more information around this and will share an update. You may refer to the article for more information about the Naming files, paths and Namespaces support in Windows Naming Files, Paths, and Namespaces - Windows applications | Microsoft Docs
From the Microsoft article:
These are the directory management functions that no longer have MAX_PATH restrictions if you opt-in to long path behavior: CreateDirectoryW, CreateDirectoryExW GetCurrentDirectoryW RemoveDirectoryW SetCurrentDirectoryW.
These are the file management functions that no longer have MAX_PATH restrictions if you opt-in to long path behavior: CopyFileW, CopyFile2, CopyFileExW, CreateFileW, CreateFile2, CreateHardLinkW, CreateSymbolicLinkW, DeleteFileW, FindFirstFileW, FindFirstFileExW, FindNextFileW, GetFileAttributesW, GetFileAttributesExW, SetFileAttributesW, GetFullPathNameW, GetLongPathNameW, MoveFileW, MoveFileExW, MoveFileWithProgressW, ReplaceFileW, SearchPathW, FindFirstFileNameW, FindNextFileNameW, FindFirstStreamW, FindNextStreamW, GetCompressedFileSizeW, GetFinalPathNameByHandleW.
So, as I understand, Acrobat Reader DC should use modern directory and file management functions in order to overcome MAX_PATH restrictions.
The application manifest must also include the
It is the quote from the Microsoft article. But Acrobate's manifest does not include such element.
I created a UseVoice request for this. It's insane that it's 2019, Windows no longer enforces a path limitation, and yet Adobe has yet to improve.
Please vote on this request, hopefully it'll get fixed: Add proper LongPath support – Share your feedback on Acrobat DC
Well, in 2019, the unability of Adobe reader DC to read long filenames is a no-go. Using structured directory and informative file names is, to me, an absolute need in a professional environement. So I'm highly surprised a company such as Adobe cannot solve this... waiting for an upgrade, I'll have to move to others (Foxit ?..)
I am having this issue with the file names being too long and pdfs not opening.
+1 for this - can't access a whole load of files that are on my network because file path exceeds 255 characters. Other file types open fine in other programs, this is just an adobe problem
