Is this a zip file?
Was the file OK previously?

Possibly/probably an hard drive failure - in which case it is very probably the file is not recoverable.

no pst

i cannot create a zip from it either

i can open it in outlook
finnstoneAuthor Commented:
this actually is not an issue if I can just format my C drive with a new windows install and keep my secondary D drive as is. is it possible to just format the primary and keep the second D drive untouched?? if so, I will do that and still have my pst file - its on the D drive

From an elevated command prompt (Run as admin) enter
chkdsk /f
and return

When finished follow the instructions here to repair the PST and see if you still get the error.

It sounds like the file is on a bad sector of the drive, or some how the file got corrupted. Since the file is so large it spans over many sectors and if any of the sectors is damaged in may have damaged your pst file making it non accessible. You can use a program such as spinrite or Harddrive regenerator to try to recover the damaged sectors. This apps do cost money but if it is critical that you are able to access the data in the pst file that may be worth the cost. You can also try copying the file to another location or to a backup drive. To see if it will be able to repair the damaged file while copying it.

i assume the file is on the D: drive?
as said, if it is on damaged sector, you can't do anything with it, even if you reinstall fresh on C:
i also recommend HDDRegenerator, it has save d many drives for me:

i hope you have a backup; if it cannot be repaired, it may be lost
