It would be pretty helpful if you elaborate a little on what exactly you are up to.

My hunch is that because of the truncated file path, you are looking at a path to part of a CAB file or something similar. The only way to access it is through the program that created it, because it's part of a large compressed directory. Typically these are downloaded software installers and the like.

A Google of "cdebconf" reveals this may be a Linux related installer of some kind.
