Override restriction on File Size over a Network

    Question

  • Hi All,

    I am attempting to move a large amount of data from an ex-employees OneDrive to our NAS device for archive storage and large files PST and Video Files are not being copied over, is there a setting that I can change to allow these larger files to be copied over.

    Please help

  • Hi Zakmk96,
    As far as I know, the maximum file size allowed totally depends on the protocol. Some protocols, for instance, use a 32-bit integer to indicate file size, limiting the size to (2^32 - 1) bytes. Some protocols use a 64-bit integer. Yet other protocols use an ASCIIZ (null-terminated ASCII string) to indicate file size, which means that the number of digits became unbounded.The destination file system then might impose additional limitations. For instance, files on a FAT32 file system cannot be larger than 4 GiB (32-bit unsigned integer maximum value).
    In my opinion, you could also involve the vendor based on the brand of NAS you are using to check if some restriction rule on NAS device caused the problem.
    In addition, since the problem related to OneDrive, I would suggest you post the question in the following forum:

    The reason why we recommend posting appropriately is you will get the most qualified pool of respondents, and other partners who read the forums regularly can either share their knowledge or learn from your interaction with us. Thank you for your understanding.

  • Hi Wendy,

    Thanks for that your help. However, I found you change the file size in the registry so I changed from 500000000 (500MB) to 4000000000 (4GB) and I can now move large PST files over to our NAS device.

    Kind Regards

    Zak
