Split Larger Image File into Multiple Smaller Files

A backup image file takes less space than an intact copy, but if the source data is huge in size, the image file can also be large. In this case, you may face following problems when trying to store the image file to a safe place:

  • The image file is too large to be stored in any of your storage devices. For example, if the image file is 6 GB, and you owns two 4 GB USB flash drives. You can apparently not store it in any of the USB. Instead, you may want to split the image into 2 image files at first.

  • You want to split an image file into several smaller fragments so as to separately store them to CD or DVD. Then a image file splitting tool would be necessary.

  • You want to store an image file larger than 4GB into a FAT32 partition, while the FAT32 partition only supports maximum file size of 4GB. Thus you have to split it into smaller-than-4GB ones to meet the storage requirement of FAT32 file system.

If you have similar problems, then AOMEI Backupper is a feasible solution allowing you to split a larger image file into smaller files.
