Open Office Documents in PDM

Please help, I have added some .doc files that were generatedin Open Office and not MS Office, the problem is that they are notvisible (even to the admin) but if I try and add the files again Iget a message asking if I wish to overwrite the existing file ofthe same name.

Any ideas what is wrong?

Open Office 3.0.0
PDM 8.03.0143
