There are a lot of zip applications around that help you in compressing files. But a lot of times, even after zipping a file the size would be too big for you to send through your favourite mail or upload site.
There is an easy solution to this problem. You can use your favourite zip application to zip and split the file into smaller chunks. This feature is available in almost all of the major zip applications.
Here’s how you split a large file without the need of any separate file splitting software (I’ll be using 7zip for this purpose here but you can do it with most of the zip apps around)
Example: I had a file of size 40 MB. I split it into 10MB each by typing 10M in the space provided.
