While importing the application package i found this error

Hi,
while importing the application package i found this error,
content _a-0000d3d1-3837-8000-d3f4-680000680000_656 32459 "Full Category Report": An error occurred while updating content [id=32459 uuid=_a-0000d3d1-3837-8000-d3f4-680000680000_656]: java.lang.IllegalArgumentException: Attempt to write over a file that already exists: /opt/applocal/dit1/appian/_admin/accdocs1/2/10019249.arf (APNX-1-4071-008).

if it is already present it should over write right?

please help me out in finding the issue....
