What do you like best?
It is safe, fast, fulfills what was promised. It is an FTP client that allows you to save several types of connections to different sites. For beginners it is very useful, multilanguage support. It has many software updates. I consider it to be the best FTP client that exists today.
If you are student a teacher or a profesional in Web development you will find Filezilla easy to use. Perfect to teach and perfect to learn.
What do you dislike?
I have been using this software for more than 6 years to manage Web sites. It has undergone improvements over time, but one aspect that could improve a bit more is the graphical interface, the interface to be in 2018 looks outdated, many applications try to be visually attractive. I would like that to see a change in the UI.
Recommendations to others considering the product
IIf it is your first time trying to enter in the web development and you do not have a good idea how a ftp works, you will find filezilla perfect for you.
What business problems are you solving with the product? What benefits have you realized?
Updating websites through FileZilla to pages made in a cms is much faster than updating the files on the website page directly with the document manager that contains the cms.
In addition you can upload Wordpress code modifications without problems through this FTP client.
Filezilla I use it often with Putty, the two complement each other for the administration of websites that run under a Linux server.
