Even though manufacturers like ABB and FANUC have implemented many tools in their respective software RobotStudio and Roboguide, I recommend the following useful tools.
Notepad++
Notepad++ is a text editor that I use when I need to check backup folders and files.
I usually open the backup folder as Workspace.
Then navigate through the sub-folders and files.
Additionally, I use a user-defined language file dedicated to ABB RAPID, FANUC TP, or STAUBLI VAL3 to enable syntax highlighting, making it much easier to read files.

Winmerge
WinMerge is a powerful tool for comparing and merging files and folders. It presents differences in an easy-to-understand visual text format.
I use this tool to analyze the differences between backups. For example, I can identify the changes that have been made since the last backup.
Filezilla
Filezilla is a free FTP solution that allows you to transfer files to/from the robot controller.
I primarily use this software for making backups, especially with FANUC robots. The process to make backups with the teach pendant requires many clicks, so Filezilla simplifies the task.
Additionally, I use Filezilla to load files onto FANUC or STAUBLI robots. For ABB robots, their software is efficient for loading programs and making backups.
Be careful when you select the download link, the installer includes bundled offers. You should go to "additionnal download options". Here is the direct link.
If you have any other helpful tools, please let me know through the contact form. I will make sure to add them to the list.
