I copied a music folder from an old USB stick to my laptop. Some tracks play normally, but others contain glitches or silent sections, so I suspect the files were already corrupted. I deleted the copied folder, but I'm worried that transferring or opening those files may have damaged other data on the laptop.
Could corrupted music files affect unrelated folders, documents, or other files on the same drive? I also opened some tracks with Audacity and Windows Media Player and copied a few to the desktop. Could that have corrupted those programs, their installation folders, or the desktop itself?
Is there anything I should do to check whether the rest of my drive is healthy and make sure my important files are safe?

The best way to reduce the worry is to maintain backups of anything important, ideally with more than one copy and at least one copy disconnected from the computer. Checksums can also help: calculate a hash for an important file and compare it with a later hash or a backup copy. If the values match, the file’s contents are the same; if they differ, the file changed or became corrupted.
There probably isn’t any tedious recovery work needed here. Corrupted tracks can be deleted and recopied from a reliable source. For extra reassurance, back up your documents now and monitor the drive, but copying a bad music folder does not by itself endanger unrelated documents on the same disk.
No—ordinary file corruption is normally limited to the affected file. A damaged music file doesn’t spread through neighboring folders like an infection, and opening it in a media player or audio editor doesn’t normally corrupt those programs or the rest of the drive. You can simply remove the bad copies and replace them with known-good versions.
The main exception would be if the drive itself is failing. A dying hard drive or a faulty USB device can cause read and write errors, which may explain why multiple files are damaged, but that’s a hardware problem rather than one corrupt song damaging other files. Check the drive’s health with a SMART-monitoring tool and run the operating system’s disk-error check if you notice more corrupted files, crashes, or unusual noises.
So if a file’s checksum changes, that confirms the file’s contents changed, while matching checksums indicate the data is unchanged—as long as the checksum method is used consistently?
