Merging Large Files

To merge the 250 GB files back together, you can use a variety of tools depending on your operating system. Here's a general approach using a Linux-based system:

Create a new file with the desired name and size. For example, if you want to merge files named file1.bin, file2.bin, and so on, and create a file named merged_file.bin of size approximately 7 TB, you can use the dd command:
```
dd if=/dev/zero of=merged_file.bin bs=1G count=7000
```
Use the cat command to concatenate the files in the correct order:
```
cat file1.bin file2.bin ... file250.bin > merged_file.bin
```
