File Size

Macrium Reflect image and backup files can comprise of either a single file or many files (known as Split Files or Splits).  The settings on this page allow you to set the Split File creation policy used by Macrium Reflect.

Setting

Description

Automatic

Let Reflect determine the maximum image file size. The maximum file size will be determined by the file system on the destination drive. For FAT32 the maximum file size is 4GB, for NTFS and optical drives (CD / DVD) the file size is determined by the amount of free space on the drive. If there is no more free space on the drive then you are prompted for a new location for the remainder of the image data. If the image file is larger than 4GB and you are saving to a FAT32 location then the image file is split into multiple files and the file number (at the end of the image file name) is incremented.

Enter a fixed size

You can enter a fixed number of MB or GB for the maximum file size. This is useful if you want the speed of a local hard disk for the initial backup, but later want to transfer the image files to CD / DVD where space per disk is limited. As soon as the file size is reached a new image file is created and the file number (at the end of the image file name) is incremented.
