I use filezilla to upload files to the server, and when I upload a small file, the process is completed successfully and everything is fine, but when I upload a large file of 30 mb or more, the process is completed successfully, but I cannot find the file. This is a problem I encountered, and I tried to transfer the same file to another server, and it was successful.
Unfortunately it is not possible to upload large files here, so you won’t be able to restore the site this way.
I’ve never really used WordPress before, so I am not sure if there is a way you can extract the file you have or something, perhaps someone else on the forum will be able to help you.
If you would rather not install special software to extract the backup, there is another way to work around it. You can install a web server on your own computer, like XAMPP, and install WordPress by hand on there. Then you can import your backup, and set up the site as desired.
Once you’ve configured the site to your liking locally, you can migrate the files and databases from your local web server to your hosting account with us.
