Why should you split large files?
Before going into the details of the steps, let's take a look at some good reasons for splitting the file:
Overcoming the file size limit
This is the most common reason. Email platforms usually have limits on attachment capacity (usually ranging from 10MB to 25MB). Similarly, many messaging applications also have the maximum file size allowed to be sent. Divide the file makes it easy to send large files through these channels.

Increase the load speed and download
For unstable or slow internet connections, uploading or downloading a large file can take a lot of time and are easily interrupted. Divide the file into smaller parts to help this process take place faster and more stable.
Easy to store on mobile devices
Some mobile storage devices, especially the older USB, may have difficulty processing files that are too large. File split to help you easily copy and manage them on these devices.
Convenient for backup and data recovery
When backing up the data, the division of large files helps the backup process take place faster and minimize the risk risk during implementation. Similarly, data recovery is easier.

- Compression method (Compressive method): For a quick breakdown process, you can leave the “Normal” option (normal). The file compression is not required when you just want to split the file.
- Split to volumes, size (Divided into sections, sizes): This is the most important part. Enter the desired size for each file after splitting. For example, if you want to divide a 6GB file into 1GB part, enter “1024m” (or “1g”). You can use units such as KB, MB, GB.

Important note when using winrar
To be able to assemble the split files with Winrar, the recipient also needs to install this software on their computer. Other extract tools or Windows's built -in extracting features may not work with files broken down with Winrar.
