Concatenate Multiple Text Files in Windows / DOS
You have a directory full of log files that you want to import into
Excel or a database so you can do some processing on them… but there are
hundreds of files… how do you make them into a single file?
Answer: Pull out your DOS hat, open a command prompt, and then use the “for” command.
for %f in (*.log) do type “%f” >> output.txt
You can also just use the DOS copy command:
copy /a *.log aggregate.txt
The /a option ensures that any ^Z’s at end-of-file in the source files will not be copied to the destination file.
