This is a non-issue if your files are stored in a partition separate from your OS, and is infeasible otherwise.
* If you have a separate partition, you can replace your OS and your file remain untouched.
* If you don't have a separate partition, your OS and your files will be replaced by the Linux installation. The only way to preserve your files is to copy to some external media before installation. Even if the Linux installer could retain files while reformatting a partition (which might be technically feasible), it would have no way of knowing which files to retain: the user could easily keep important files in arbitrary directories, not just in their designated C:\User\Patrick directory, and they would be understandably irate if the installer promised to keep files but didn't. To say nothing of adding complications of copying files that Windows has pushed to OneDrive.

That is one of the biggest ifs of 2026. I don't think any major PC laptop vendor has ever sold consumer laptops with anything but one-big-partition layout. For the average user, their files are not stored in any partition, they are stored "right there on my desktop, with a separate folder for photos and bills"
EFI/ESP and a restore partition have been standard or at least common for a decade. Restore partition might be big enough to install to… my Linux system partition is only 30GB.
But yes, been using a /data partition since it was called D:\ under DOS.
