Challenge: edit or view huge .sql files
Solution: use the PilotEdit free application that can edit and compare large files
Programmers, especially those specialized in databases, often run into the problem of opening big SQL files. Databases exported from production environments can have a couple of GBs, or even more.
In this tutorial, we will learn how to open or edit these huge files.
Opening big files
Usually, if you try to open a text file that is over 100MB, your Text Editor will freeze and you will wait a long time to see the opened content. Trying to edit text or save the file will cause longer waiting time or a crash.
PilotEdit is a Windows program that solves this problem. The Lite version is free to use and allows editing files up to 10GB. To support larger files, even 400GB in size, a License needs to be purchased.
When opening a file, PilotEdit reads the file byte by byte. Once finished, you will see a text editor with your SQL content. The application is fast, you can easily scroll through the file or jump into a different part of the content.
Lite vs Paid version
For previewing and editing database files up to 10GB, the Lite version is a good choice. If you need additional features or faster performance when working with huge files, the paid version is recommended. Are you curious about the differences between the free and paid versions? Here is a comparison table.

Summary
PilotEdit can be recommended for every developer working with databases. Sometimes, changing the characterset and collation of DB requires editing the dump of a SQL file. With PilotEdit, it is an easy change. Even huge files (a couple of gigabytes, in the paid version – hundreds of gigabytes) can be handled without a problem e.g. during the process of app development.
