File Ordering help

Hi there,

We have set a file/folder structure so that the top level sites are 1, 2, 3 4 then the subfolders within are 1.1, 1.2, 1.3 etc.

For some reason if we set the column order so that is orders the files and folders by this number is does this:

1.1

1.10

1.11

1.2

1.3

1.4

1.5

1.6

1.7

1.8

1.9

It sets 1.10 and 1.11 (and so on) next to 1.1 in the list although it should be ordering so they show after 1.9.

Can you help with this please? It's making the file order very confusing.

Thanks
