On two separate Alfresco 4.2.c installations, it's impossible to create a new folder of which the name consists of 8 or more numbers. So for example a date isn't possible: '20131025'. I get the error 'can't read from disk'.
When I use dashes in the name, there is no problem: '2013-10-25'.
Naming the folder with 7 number isn't a problem as well: '1234657.
Using 8 letters works as well: 'abcdefgh'.
After experiencing these problems, when I delete the problematic folders, they aren't really deleted. I can still see them in Share and can't create a new folder with the name of the before renaming this to a problematic name ('New Folder', for example).
In Share I can create a folder with 8 or more numbers without any problems.
Why is this? This seems like a bug to me.
I'm using the Webdav-implementation Windows 7 x64 and connect over SSL to Alfresco Webdav. I use the following command to connect the drive: "NET USE N: \\example.com@SSL/alfresco/webdav".
