How to merge multipl

1. Easily Merge Word Document
Most of us work with Word document often and sometimes we indeed need merge multiple word
documents into one master file. To merge word documents into one master file could be very
easy although Word doesn't have a directly import/export function to do that.
Merge Word Documents in Microsoft Word
If we just need merge 2 or 3 word documents, we can easily use Word “insert” function. Open the
first Word document and just insert the second document at the end of the first word document
content by clicking “file” from tool bar “insert” category. Then, repeat this if you want to merge
the third document into the master file. At last, save it. This function enable us select multiple
word documents by press “Ctrl” or “Shift” and merge them into one master word file. But the top
file you select will be merged first. So if there is an order that you want to maintain, make sure to
rename the files first so that the appearance in order in the dialog box.
Note: Sometimes when you merge Word documents this way, the formatting does not always the
same as the original. So, you may manually fix it.
