  6. Where do i put the files in USB ??? seperate folder ???

  7. Can you share the download link for 32 bit. I could not find it on the microsoft developer center…

  8. What would cause my USB stick to become unusable and when I go to format it in Windows it says it’s unknown size and I can’t get it to work in the cmd anymore??


    DiskPart succeeded in cleaning the disk.


    No usable free extent could be found. It may be that there is insufficient
    free space to create a partition at the specified size and offset. Specify
    different size and offset values or don’t specify either to create the
    maximum sized partition. It may be that the disk is partitioned using the MBR di
    partitioning format and the disk contains either 4 primary partitions, (no
    more partitions may be created), or 3 primary partitions and one extended
    partition, (only logical drives may be created).
