Hi,

   I am using the DirectoryInfo class to create directories. However there is a 260 character limitations to the length of
   the directory name which I maxing out on. Any way around this ?



Thanks

What kind of directory has a name that is more than 260 characters?!?
(hmm... and I thought windows set a limit at 254 chars... odd that .Net lets you add a few more.  I could be wrong though.)


At any rate, I am going to guess that you are NOT creating a directory name of 260+ characters, but are in fact trying to create a subdirectory several directories deep.

Assuming that is the case, you could get to 260 characters pretty fast.


If this is the case, you do not want to use DiretoryInfo class.  This class is geared for Instances of directories.


use this code:

Directory.CreateDirectory(strAReallyLongDirectoryStructure);

Ack!


Ok... I tried out my own code and got the same error.

It looks like you'll have to do it recursively in order to get it done.

Turns out it is a Windows limitation


Try doing it manually and you'll get all kinds of errors.

C:\temp\subFolderOrDirectoryWithReallyLongName\subFolderOrDirectoryWithReallyLongName\subFolderOrDirectoryWithReallyLongName\subFolderOrDirectoryWithReallyLongName\subFolderOrDirectoryWithReallyLongName


works just fine.


C:\temp\subFolderOrDirectoryWithReallyLongName\subFolderOrDirectoryWithReallyLongName\subFolderOrDirectoryWithReallyLongName\subFolderOrDirectoryWithReallyLongName\subFolderOrDirectoryWithReallyLongName\subFolderOrDirectoryWithReallyLongName


Throws an error in windows and it was really easy to test manually.
