Compare archive paths and file counts, inspect a small folder example, and keep extracted downloads separate from the original ZIP.
Start by inspecting the archive's file list. A folder name, a file name and an empty file are different entries. Keep the original ZIP until the files you need have been extracted and opened successfully.
Worked example: Check a nested archive
Input
A ZIP containing notes/todo.txt and images/logo.png.
Expected result
Two files in their respective folder paths, with the text file and image available as separate items.
The compressed archive size is not the size of its extracted files. File names alone do not prove that a file is safe to open; review the source of the archive before running anything inside it.
Before you use the result
- Compare file names, folder paths and file counts.
- Check the size of extracted files as well as the compressed archive.
- Open the saved files you actually need before deleting your source copy.
If the result is not what you expected
An archive cannot be opened.
It may be incomplete, damaged, encrypted or unsupported. Obtain a complete copy from its source rather than assuming a different file extension will repair it.
