In Windows if you try to delete a excessively long filename- you get a message that the file cannot be stored in ‘Recycle’. BUT it should delete. Failure to delete can be ‘Norton NProtect’, files that the local user doesn’t own (right click and check advanced on the security tab), or that are in use. If you don’t have IE open then a file in temporary internet that errors with ‘in use’ is scary.
Do you get a specific error message?
