Problem description: expdp exports the dmp file, but the dmp file is incorrectly named during the export operation. Mv renames the exported dmp file. What effect does this have on impdp operations?

Conclusion: as long as the command is typed correctly and the file name is written correctly, the impdp operation will not be affected.
