I'm considering replacing Windows with Linux, but I'm worried about losing my personal files during the installation. Should I simply back them up somewhere first, or are there safe ways to keep them on the computer? I may either erase Windows completely or install Linux alongside it, and I'm not sure how those choices affect my files. English isn't my first language, so apologies if the question is unclear.

If you're going to erase or replace the Windows partition, back up everything important first—documents, photos, videos, music, browser data, and anything else you care about. Copy it to an external drive or another computer, and make sure the files can actually be opened before starting the installation.
Even if you plan to dual-boot, a backup is still the safest approach. Your files may remain untouched if they are on a partition you don't modify, but partitioning and installation mistakes can still cause data loss. Treat the backup as necessary rather than optional.
Keep the backup disconnected from the computer while installing Linux. That way, if you accidentally select the wrong disk or partition, the backup remains safe. An external hard drive, network storage, or another computer can all work; a USB stick is fine only if it has enough capacity for your data.
If Windows stays installed, Linux can usually access files on Windows' NTFS partitions, and you can also store shared files on external or network storage. However, compatibility doesn't replace backups. Before changing partitions, identify exactly which disk will be erased and copy important files somewhere separate.
