    Split Archives with WinRAR

    Prerequisites:

    * WinRAR (3.62 or higher recommended)


    Instructions:

    If you wish to split a file into multiple-parts you will have to define what size each part should be (by default, the value is represented in bytes). The size will depend entirely on the maximum file size your uploading site requires (Rapidshare.com allows 100 MB files - and will be used during this tutorial)


    File sizes - The hard way...

    We'll start by converting our host's maximum file size into bytes, to work out the byte-value, for each part. Here is a table explaining the conversion process:

    Code:
    bytes > kilobytes > megabytes > gigabytes
    1024 / 1024 / 1024 / 1024

    Code:
    bytes < kilobytes < megabytes < gigabytes
    1024 x 1024 x 1024 x 1024


    When working from a lower class to a higher class, you simply divide your file size, by 1024. When working from a higher class to a lower class, you simply multiply your file size, by 1024. If we wish to find out how many bytes are in 100 MB, we simply multiply 100 MB by 1024 (100MB x 1024 = 102400 KB), and by 1024 again (100MB x 1024 x 1024 = 104857600 B). This tells us, that there are 104857600 byes in 100 MB. Here are some other examples:

    Code:
    50MB = 52428800 B (50x1024x1024)
    100MB = 104857600 B (100x1024x1024)
    200MB = 209715200 B (200x1024x1024)
    500MB = 524288000 B (500x1024x1024)
    1GB = 1073741824 B (1x1024x1024x1024)


    File sizes - The easy way...

    Go to T1 Shoppers Byte Converter, enter your file size and type, and click convert Smile


    WinRAR - Creating multiple parts...


    Once you've calculated the size of each part, its time to make them using WinRAR. Right-click on the files/folders you wish to use, and select "Add to archive..."



    When the WinRAR window appears, enter the byte value (part file size) in the "Split to volumes, bytes" box in the bottom left hand corner. TIP: it is usually recommended to make the file just under the required size. You can do this by replacing the last 4 numbers with 0's. For example, if you are creating 100 MB parts, enter 104850000 instead of 104857600.



    At this point, WinRAR will automatically create separate parts, with the size you specified in bytes. If you wish to add a password to the archive, click on the "Advanced" tab at the top, and then click the "Set Password" button. In the password box, tick both of the options listed, and enter your password.



    Once you have done that, simply click OK, and OK again, and WinRAR will create your .RAR files Smile
