Error when copying files from Files app on iPad to samba share

This is not true.

I have an Ubuntu 22.04 server with SAMBA server installed.

From the File APP on iPad I was only able to copy the first photograph, then subsequent copies, whatever the name or size always return the error "Unable to complete operation. File name too long."

If I consider the entire network path "smb://10.25.25.100/iPhoneFoto/IMG_0789" it is only 38 characters long.

From linux PC I can write any file or movie to the folder, even with longer names.

The error that the FILE utility returns is misleading.

My iPad is an iPad Pro with iOS 16.3.1 installed.

How can the error be resolved?

Thank you

Now you have a lot of information, how can I solve the problem?

Is it a problem with the iOS File APP ... should I use another APP?

What do you think is the best APP to use?

Thank you for your support.

Given your difficulties with the native Files App, you might be best advised to try something else.

My own preferred choice for document and file management is FileBrowser Professional by Stratospherix:

https://apps.apple.com/app/filebrowser-professional/id854618029

This App will reliably and flexibly connect with almost any file storage system, including USB attached storage. The App has a learning curve to get the best from it, but once set-up, is simple to use. You might review the extensive online Manual and help files to determine suitability for your needs.

In absence of other information, I had merely suggested the path/filename limit as a potential problem with some platform; at no point had I stated this as the definitive cause of your issue…

The path/filename may be limited. For some system implementations, this may be 260 characters.
