I checked their FAQ. This is what they write:
"On December 1, 2023, there were significant changes in the functioning of the cloud storage Uloz.to Disk and PINKfile.cz. The changes are a forced response to the upcoming European legislation known as DSA.
From Friday 1 December 2023, cloud storage services are only accessible to registered users. Newly, the content is accessible only to those users who uploaded it to the repository themselves."
Basically the only way to share files on uloz will now only be possible if the uploader shares the log-in credentials to the account. I doubt anybody will share their credentials.
I have noticed that the search engines have all been disabled as well.
The files have not been deleted, so the subscribers have the option to move their files to another host.
If other filehosts are based in an EU country they will probably enforce similar rules. At least if they interpret the rules the same way.
This is the text that uloz based their decision on in a statement to the press:
DSA (Digital Services Act)
Groundbreaking Regulation 2022/2065 on the single market for digital services and amending Directive 2000/31/EC (Digital Services Regulation), English. The Digital Services Act ("DSA") comprehensively regulates the digital services sector within the EU and aims to ensure the proper functioning of the single market, maintain a safe online environment and protect the fundamental rights of users. The DSA sets rules and obligations for digital services that act as intermediaries, i.e. connecting users to goods, services and content. This is the entire spectrum of digital services, from services providing network infrastructure, through web hosting to online platforms such as social networks or Internet marketplaces. Specific rules for individual subjects are designed asymmetrically. Services with greater social and economic impact must therefore meet stricter conditions.
Uloz offer of 50 GB storage for free registered users seems to have no value.
My guess is the site probably will close soon like Uploaded did.
