A ZIP file is an archive container, not an M3U or XMLTV document. If a legitimate source supplies an archive, inspect and extract its intended contents locally before choosing the matching import method. Renaming the ZIP to .m3u changes the filename but leaves the archived bytes unchanged.
Inspect the archive contents
An archive can contain several files, including instructions, artwork or unrelated documents. Identify the actual playlist or guide rather than selecting the first file. Do not run executable files merely because they arrived beside a playlist.
Keep extraction private
The extracted playlist may contain credentials in stream URLs. Choose a private folder rather than a public cloud share or shared household download directory. Remove obsolete extracted copies when they are no longer needed.
Prefer the supported delivery route
If the player expects a remote URL and the source supplied only an archive, ask for clear instructions. A local file import and a remote account profile can behave differently on later updates.

An example to work through
An archive containing channels.m3u and readme.txt should not be entered as one channel URL. The reader needs the intended playlist file or a supported remote source.
Questions about this topic
Can renaming decompress the archive?
No. Extraction is a separate operation.
Is every file inside a playlist archive safe to run?
No. A playlist does not require executing unrelated programs.
