Merging Microsoft Word documents
To merge Word documents, you can merge those documents within Microsoft Word itself. To do this, open the first file in Microsoft Word, and follow the steps for your version of Word. The steps are different because of the changes between the file menu and the Office ribbon.
Microsoft Word 2007 or later (Ribbon)
In the Word Ribbon, click the Insert tab, click the down arrow next to Object, and select the Text from File option, as shown below.
Select the file you want to merge into the current document and click Insert. Once completed, the text and other information from the document will be merged into the current document. These steps can be completed as many times as you want if you want to merge multiple files.
TipIf there are multiple files you want to merge at the same time, you can select multiple files by holding down the Ctrl key and selecting each file you want to merge.
Microsoft Word 2003 or earlier (File menu)
In Word, click on Tools in the top menu and select the Compare and Merge Documents option, as shown below.
Find the document you want to merge. You have the option of merging the selected document into the currently open document or merging the two documents into a new document. To choose the merge option, click the arrow next to the Merge button and select the desired merge option. The files will then be merged.
TipIf there are multiple files you want to merge at once, you can select multiple files by holding down the Ctrl key and selecting each file you want to merge.
Merging Microsoft Excel files
To merge Microsoft Excel files together, it is best to save them as CSV files first. Open the Excel files and in the menu bar, click File, then Save As. In the Save as type drop-down list, select CSV (comma delimited) (*.csv) from the list.
Do this for each Excel file you want to merge, then place all the CSV files in the same folder. For ease, place them in a folder in the root of the C: drive (e.g., c:csvfiles).
Open the Windows command prompt and navigate to the folder containing the CSV files. Type dir to view the files in the folder and ensure all the files are there.
Type in the following command to merge all CSV files in the folder into a new CSV file titled 'newfile.csv' (any name could be used).
After the new file is created, open the new CSV file in Microsoft Excel and save it as an Excel file.
Merge a text (.txt) file in the Windows command line
Place each of the text files you want to merge in the same folder. For ease, place them in a folder in the root of the C: drive (e.g., c:textfiles) and make sure the folder only contains text files you want to merge.
TipCsv File Windows 10
Before merging text files, you may want to make sure there is a blank line or at least one carriage return (pressing the Enter key) to help separate each file.
Open the Windows command prompt and navigate to the folder containing the text files. Type dir to view the files in the folder and ensure all the files are there.
Type in the following command to merge all TXT files in the current directory into the file named newfile.txt (any name could be used).
Now you can open the text file and see everything merged together as one file.
Merge a file in the Linux command line
Linux users can merge two or more files into one file using the merge command or lines of files using the paste command.

PDF documents can also be merged. You can use a full version of Adobe Acrobat to do this, but this program is a bit pricy (several hundred dollars).
Another option is to find a free utility on the Internet to merge your PDF files. One of the better free utilities is PDF Split and Merge. It is an online tool that lets you merge two or more PDF files into one PDF file with a few clicks of your mouse button. Explorer 8 download windows 7.

It is recommended that you use a utility on your computer for these types of PDF file mergers, to ensure the confidential data is kept confidential.

Here’s a useful tip if you ever need to combine multiple CSV files into one CSV file. This may be useful if you need to run reports (such as a crystal report) based on the data – where you need the data to be in a single file.
Option 1 – CSV files without a header row
The following single command line will combine all CSV files in the folder as a single file titled ‘combined.csv’
If you want to run this from a cmd file, copy the following contents into a text file and save as ‘run.cmd’.
This command will automatically run from the folder the file is saved in, that is – if you save it to C:TEMP it will look for CSV files in C:TEMP and save the new file to C:TEMP
Option 2 – CSV files with header row
So what if your source files have a header row? The following command will take the header from the first file, then exclude it from the rest. Copy the following contents into a text file and save as ‘run.cmd’.

You can download an example of this script here: www.itsupportguides.com/downloads/csvmerge.zip
Note: this process will not work for XLS (or similar) files – CSV files are text files, their data can be easily accessed using scripts where as XLS files are binary files and require an application such as Microsoft Excel to access the data.
