Hi All,

  When i run the below code in windows i am getting "The system cannot find the path specified" even though the path exist , the length of the path is 516 as below, request your help.

Path :
N:\PROD_TEAM\TST_BACKUP\abcyf0\TST_BATS\j2ee_backup\cluster\states0\apps\bat.com\tc~bat~agent~application~e2emai~std~collectors\servlet_jsp\tc~bat~agent~application~e2emai~std~collectors\root\WEB-INF\entities\DataCollectionPushFileContentScannerTypeBuilder

Program:
void SizeDirList (string[] SzDNDlst)
{
 auto logF = File(LFpath, "a");
 ulong subdirTotal = 0;
 foreach (string i; SzDNDlst[0 .. $])
     {
      auto dFiles = dirEntries(i, SpanMode.shallow).filter!(a => a.isDir && !globMatch(a.baseName, "*DND*")).array;
	  foreach (d; dFiles)
	        {
				auto SdFiles = dirEntries(d, SpanMode.breadth).array;
				foreach (f; SdFiles)
					{
						subdirTotal += f.size;
					}
				   ulong subdirTotalGB = (subdirTotal/1024/1024/1024);
	               if (subdirTotalGB > SizeDir)
			            {
	     	                writefln("%-63s %s", d, subdirTotalGB);
				        }
						subdirTotal = 0;
		    }	
	 }
}

On which line do you get the Exception? Does it happen with shorter paths, as well?
Assuming it happens with all paths: Just to be sure, is each of those backslashes actually encoded as a backslash? If you specified the path in the D source like `path = "N:\PROD_TEAM..."`, then it won't be, because backslash is an escape character (you would need to write `path = "N:\\PROD_TEAM..."`, or better yet path = "N:/PROD_TEAM..."`).

Hi,

  The above program scan for files/directories under the main folder N:\PROD_TEAM\ and reports the size of each of the sub folders eg: "TST_BACKUP", under the main folder "N:\PROD_TEAM\" there are more than 9000+ files/directories, eg: (N:\PROD_TEAM\TST_BACKUP,N:\PROD_TEAM\PRD_BACKUP\....)  and the above program will output the size of the sub folders "TST_BACKUP,PRD_BACKUP",  there is no issue is the path is shorter, the issue arises only when the path is bigger, eg the program prints the size of the sub folder PRD_BACKUP but when it tries to scan the sub folder TST_BACKUP the issue arises and the program terminates with the exception "The system cannot find the path specified", hence it not not be possible to provide the path explicitly, so can you help me on this.

While that is good to know, you still haven't answered my initial question:

>> On which line do you get the Exception?

If your program terminates because of an uncaught exception (as you stated), then you should've received a stack trace containing the line number on which the exception was thrown (remember to compile with debug info).
You should also consider providing a compilable, minimal example (with test data) that can be used to reproduce the issue.

Windows has a 260-character limit on file path names. This can be disabled in Windows 10 for applications that ship with a manifest, but that isn't going to help you. If the Phobos functions are using the Win32 API internally, and specifically the Unicode variants, then you should be able to get around this by prepending "\\?" to any file path you send to the API. That's how long file paths have been handled in Win32 to date. If it doesn't work with Phobos, then you'll need to call Win32 directly and Phobos should be modified.

The line it complains is std.file.FileException@std\file.d(3713): even after enabling debug it points to the same

Output:
D:\DScript>rdmd -debug Test.d -r  dryrun

You need to compile with debug info (option `-g`), not compile in debug code (option `-debug`).
What's the (full) stack trace when compiling with debug info?
