Subject: bug#17938: Very long path name can not handle in windows mingw emacs.
Date: Sat, 05 Jul 2014 00:05:54 +0900 (JST)	[thread overview]
Message-ID: <20140705.000554.460429865.trueroad@trueroad.jp> (raw)

Hello.

Very long path name files can not handle in windows mingw emacs.

GNU Emacs 24.3.1 (i386-mingw-nt6.2.9200)
GNU Emacs 24.3.92.1 (x86_64-w64-mingw32)
etc.

It is a path name over about 260 characters.
The files and folders are not displayed in dired.
So they are unable to open.
When you drag and drop the folder from explorer, emacs shows a message like
"Directory /long/path/name/folder inaccessible or nonexistent".


I think that the following is the cause.
In the mingw environment, MAX_PATH is defined as 260.
Emacs source src/w32.c uses MAX_PATH for filename buffers.
However, NTFS (NT File System) can handle longer path name than 260 characters.

Thank you.
