Is there a path limit for compressed files in a windows directory structure?

Hi All,
I've got an issue where we have some of our network directories compressed (standard windows built-in zip compression) and after a certain depth in the pathname, documents cannot be opened.
For example, J:\Directory 1\Directory 2\Directory 3\Directory 4\Directory 5\Directory 6\Directory 7\Directory 8\Office document.doc cannot be opened after approx 100 characters deep in the path name.
The cursor just flashes for a second and then nothing happens. HOWEVER this only seems to be affecting Office documents, Word, Excel, etc as i've successfully opened PDF documents from paths where the Office ones will not.
If you copy the document from the deep path to a shorter one it will open, so the documents are not corrupted.
Any ideas on whether there is a character limit/directory depth limit when using this compression?
Thanks!

Hi redrumkev, thanks for the link but it doesn't quite answer my question. The path i'm trying to access is only about 100 characters deep so nowhere near the 255 char limit. Also, the issue appears to affect office files but not other types, ie: acrobat, etc..
Any other ideas?
Thanks

You have "J:\" mapped as a drive. How long is the path that "J:\" is mapped to?

Office is SP2, and the J: mapping only adds an extra 20 or so characters.

Thanks - believe it or not, when I checked the server and got the full path name it ended up being a lot longer, it was just shared from a deep path but the original looks like it takes it over the 255 char limit! cheers
