when the file name and size on a download page do not match
A download page states the installer file name and size. If the file your browser saved shows a different name or a very different size, it is not the file the page promised.
To judge a download page, compare the file name and size it lists against the file your browser actually saved, and do not install if they differ.
Key points
Check the file name
The page usually spells out the file name, the part ending in .apk or .dmg. If the name in your downloads folder differs, stop before installing.
Compare the file size
The page lists a size for the installer. Open the same file's properties after downloading and compare the numbers; a clear gap means it is not the same file.
Read the developer name
The app store listing has a developer name field. Compare it with the company name at the bottom of the download page or in the about screen.
Check the download domain
The domain in the address bar should match the official domain named in the page text. A domain with one extra or missing letter is a copy.
Common questions
The file size on the page is slightly off from what I downloaded. Is that normal?
A small gap can come from different counting methods, but a large gap is not normal. Trust the number the page states and re-download from the official entry if it does not match.
There are two apps with the same name in the store. How do I pick?
Look at the developer name field and compare it with the company name on the download page or official site. Install only if the names match.
