    ISO files over 4Gb

    How can I make an ISO file of more than 4Gb? Have a folder as I'd like to have made to a file instead, but so far it can not be done. Have tried with some programs but without success.

    Any suggestions?

    Why should it be an iso file when it is a directory? Burn it as just rather than on a DVD-write, if that is what it is you want.

    if your hd is running FAT32, you can not make iso files on more than max 4GB, so you must convert it to ntfs before you can get it, FAT 32 does not support files over 4GB!

    You must have a program that supports 64 bit file manager. Most programs (for 32bit windows) only supports 32bit, and so is the maximum file size of 4GB.

    Then a new window closes up. (Command prompt)

    So writes convert c: / fs: ntfs and hit "Enter" begin to convert the entire C drive to NTFS file system, after the restart.
    (is it a different drive than C:, for example. E: then write it instead, another drive does not require rebooting)

    When you press "Enter" one should not touch the computer, after which it may take some time before it is finished.

    By typing convert /? You get all the different commands forward.

    And you should not lose any data while converting your drive.
    But the best result is that the Format for NFTS file system, but also lose all their data. So it is best to do it on the new drive you buy and put in the PC.
    NFTS file system is more secure than FAT32 and it is not as fast fragmented.

    PS: keyword for Google Convert FAT32 to NFTS

    Could not you just elaborate what you mean by that ?

    I've programmed both the C64, Amiga, DOS 8bit, 16 -, 32 - and 64bit windows, and I KNOW that the usual objects (in OP) is used for 32bit file manager only supports files up to 4GB.

    When you are programming in 32bit windows, the general address storage limit of 4GB (32bit = 4,294,967,295 bytes). It requires special manipulation of figures, to get over this limit - but it is certainly not impossible.

    The eternal law. It is FAT32 file system which does not support more than 2 ^ 32 = 4,294,967,295 bytes. I think you think of the page file in a 32-bit OS, which max may be the 4 GibiBytes.

    Try Ultraiso, has just tested it and I may well create isofiler over 4GB.

    It is not correct since, it is wrong?! Max file size in NTFS is near 2 terabyte as I recall, not at this point is particularly relevant.

    Somewhere else, it is logical that ntfs can handle files over 4GB. Otherwise, it would indeed example, have done DVD rip in ISO format for a near-impossible until we got 64bit OS. As it is written in the thread FAT32 disks can not handle files over 4GB. Do not know about it is that you have in mind, or whether you might think of RAM limit of 4GB on 32bit. The short of it long ... Of course it is possible.
