can not read bkf file bigger 4gb of any other file bigger than 4gb

Discussion in 'Virtual PC' started by B van der Woude, Mar 6, 2008.

  1. When i copy my backup file that is above4gb to my virtual harddisk and i want
    to read the backup file with NTbackup then NTBackup reports that it is not a
    valid file, so i can not restore anything from this file, my harddisk is not
    running out of diskspace.
    If i use a BKF file below 4gb then it is not a problem.
    Also if i use the bkf file trough a shared folder of virtual addition then
    this error also occurs.

    Is this a limitation?

    Thanks in advance,

    B van der Woude

    What file system are you using on the VHD?

  4. It seems like it is whit every file above 4gb that cannot be opent.
    Winzip10 supports openingfiles above but also when i try to open a zip above
    4gb in virtual pc winzip says that its not a valid winzip file.
    When i create an bkf file below 4gb NTbackup can read the file

    Also in another virtualpc environment it is the same problem.

  5. I know you said you are using NTFS, but is that the host? Are you sure
    you're not using FAT32 in the guests?

  6. Yes i am sure.
    I tried opening the zip file on my local pc and it does open.
    I tried opening it trough the virtual additions share in virtual pc so the
    file is still on my local pc and it gives an error that the zip file is not
    valid.
    Then i tried to copy the file to my virtual harddisk wich is NTFS and then
    tried to open. It still says that the zipp is corrupt.
    Also in another virual machine on a other pc it is the same problem.

  7. Hi,
    It is probable that your bkf file has corrupted.Here are some BKF file recovery tools you may need to repair your BKF file. Below is a list of them:

    Most of them provide a free demo so you can try first.
