Getting files onto the server.
WHERE TO PUT THEM
Website files: public_html, or the directory for that addon domain.
Check in cPanel which directory a domain uses.
FOR A LARGE NUMBER OF FILES
Compress them locally, upload the archive, extract on the server.
Far faster than transferring thousands of small files.
File Manager can extract archives.
WHAT TO CHECK AFTER UPLOADING
The file count matches Permissions are correct Hidden files transferred
TRANSFER MODE
Automatic is correct for almost everything.
Binary mode for images and archives; text mode can corrupt them if forced.
Most clients handle this correctly by default.
WHAT GOES WRONG
A transfer that stops partway and is not noticed Files uploaded to the wrong directory Hidden files missed
VERIFYING
Compare total size against the source.
FOR OVERWRITING
Back up what you are replacing first.
