If you wish to divide a Word file into smaller segments, you can utilize VBA or a free online tool to expedite the process.
1. Slicing Word Files into Smaller Segments Using VBA
Within Microsoft, you can employ VBA – Microsoft Visual Basic for Applications – to partition a Word file into multiple smaller files based on predefined markers.
Step 1: Before intending to split a Word file into multiple smaller files, you need to create markers at the cutting positions.

Note: You can cut the file at any position within the Word document, not necessarily at the end. Segments between pages, 2/3, 3/4 pages are all cuttable. Just ensure you insert the 'Cutting Position Marker Code' at the desired cut point.

Step 2: Then, press the Alt + F11 combination to open Microsoft Visual Basic for Applications.
Next, select Insert => Module to add a new Module into Word.

Step 3: In the Module window, simply copy the code snippet below for pasting.
Sub SplitNotes(delim As String, strFilename As String)
Dim doc As Document
Dim arrNotes
Dim I As Long
Dim X As Long
Dim Response As Integer
arrNotes = Split(ActiveDocument.Range, delim)
Response = MsgBox('This will split the document into ' & UBound(arrNotes) + 1 & ' sections. Do you wish to proceed?', 4)
If Response = 7 Then Exit Sub
For I = LBound(arrNotes) To UBound(arrNotes)
If Trim(arrNotes(I)) <> '' Then
X = X + 1
Set doc = Documents.Add
doc.Range = arrNotes(I)
doc.SaveAs ThisDocument.Path & '' & strFilename & Format(X, '000')
doc.Close True
End If
Next I
End Sub
Sub test()
'delimiter & filename
SplitNotes '///', 'Name '
End Sub

Step 4: To name the resultant smaller files after cutting, simply delete the Notes section and replace with the filename.
The smaller files after cutting will be named as follows: The name you set + 001/002/003…099

Step 5: Finally, all you need to do is press F5 to execute the split command in Word.

Step 6: At this point, the Microsoft Word window will appear asking whether to split the file into multiple smaller files. Simply select Yes to automatically proceed with the splitting process.

Step 7: That's it! You've completed splitting the Word file into multiple smaller files using VBA.
