Reassembling A File
To reassemble a previously-split file:
  1. Find and right-click the split file of the group which has the extension .001 (referred to as the 'index' file of the group).

  2. Choose Split File: Reassemble on the ShellToys XP menu.

  3. The assembler utility will appear. Click Assemble.

  4. The assembled file will be recreated in the same folder as the split-file parts.

Alternatively, if a copy of the Assembler is included in the same folder as the group of split files, simply start the Assembler. It will locate the 'index' file automatically, and you just need to click the Assemble button.
