I don't have a build environment to build and test modified binaries; but can
test if someone can produce those...

Thanks for retesting, Eneko. I still couldn't figure out what else it depends
on, because for me for long paths the path segments are substituted with their
8.3 variant, which doesn't cause an error.

Comment 5 from V Stuart gave me a hint, though, and I tried with LO dialogs.
The setting can currently be found in expert configuration: set
UseSystemFileDialog to false.
With that I can simply reproduce this bug by navigating a long Windows share
path. Getting to a level too deep gives the same error, with the share's first
character being cut off.

himajin10's code pointer is also spot on, this line is copying the path
incorrectly, cutting off the first character:
rtl_uString_newFromStr_WithLength( , aBuf + 2, nNewLen - 2 );
https://opengrok.libreoffice.org/xref/core/sal/osl/w32/file_url.cxx?r=ab9b67bb#699

However, the problem might actually be in GetCaseCorrectPathName(...) call,
which cuts starting "" (technically two backslashes) to "\\" (a single
backslash), if this wasn't the case, the previously mentioned code would be
fine:

I tried with LibreOffice 5.2 and also with 6.1.3.2 x64, and continue to
reproduce the issue on Windows 2012r2 (dind't test in other systems).

I have tried clicking from Windows file manager and also from LibreOffice's
open dialog.

Windows is Spanish / Spain.

--- Comment #14 from Aron Budea  ---
I tried reproducing this again, but for some reason now the long path elements
are replaced with an 8.3 shortened version, and the bug doesn't occur. Eg. in a
path similar to comment 8's, "4 PRODUCCIÓN" becomes "4PRODU~1".

Surely this depends on something else as well, I wonder what.

Reproduced using a 6.0 daily build (2017-09-11_06:28:48,
ffeb750163909e15ee0dd2d16f8030bf08e66eae).

It has to be a network share, for local paths it seems to work, right?

Could you attach error message and write full correct path?

Windows can in fact use PATHs longer than 260 chars, using unicode paths, and
LO is trying to use them (they start with "\\?\"). Problem is first server char
is lost.

Error message shows path starting "\\?\UNC\erver\..." but it is wrong, should
be "\\?\UNC\server\..."

It was the Windows OS explorer dialog, but I tried with LibreOffice dialog as
per your instructions, and the same error appears.

I can see path has one non-ascii char (Ó), maybe that's the problem?. I tested
putting more non-ascii chars in the file name, but the same error remains (no
difference in lost chars in server name)

Thanks

Was that the OS Windows explorer dialog, or had you enabled internal
LibreOffice Open/Save dialogs from Tools -> Options -> General:  checkbox "Use
LibreOffice Dialogs"

Also, build details for the LibreOffice install? Simply clip from the Help ->
About LibreOffice dialog.

Thanks.

Maximum Path Length Limitation
In the Windows API (with some exceptions discussed in the following
paragraphs), the maximum length for a path is MAX_PATH, which is defined as 260
characters.

Not sure if LO's bug, for example I can not copy file into directory long path
with Windows Explorer (win7).
