https://issues.dlang.org/show_bug.cgi?id=17167 --- Comment #2 from Atila Neves <atila.neves@gmail.com> --- After some investigation, it seems that dub specifying relative paths makes it more likely to pass the 248 character limit, since Windows first appends the current absolute path to the relative one. This is a known Windows limitation up until an opt-in in Windows 10 to make the problem go away, and otherwise has to be dealt with by calling the Unicode-aware Win32 file APIs. --

Hi All,

  As per the issue id 17167 it states that this issue is resolved, but the
issue still persist as it tested with DMD32 D Compiler v2.079.1-beta.1 on
Windows 2008 R2. so as a temporary solution we have used the UNC path as below

Original Path : C:\Test\1\2\3\4\5\6.............\
UNC Path : \\?\C:\Test\1\2\3\4\5\6.............\

Issue : The appending of UNC path is consuming time and memory as it appends to each file's and folders inside the file system.

Note: The file system is a windows share from Netapp.

May i know when will this be fixed.

From,
Vino.B

Before the fix, if the dub path with several .. was too large (which happened often), nothing would work. Now, it does. It's possible that passing in an absolute path is different. I would still say that it's a new bug. --
