ZIP & Unzip

Packs several files or folders into one ZIP file, and lists and extracts the files inside a ZIP you received. Use it when you need to zip or unzip something without installing a program.

How to use

1. To pack, open "Make a ZIP" and drop files or folders onto the box, or press "Choose a folder".
2. Set "Compression" and "ZIP file name", then press the "Make ZIP" button; the ZIP file downloads.
3. To unpack, drop a ZIP file onto "Open a ZIP". The file names, sizes and dates appear in a list.
4. Press "Download" next to the files you need. Images and text files can be checked first with "Preview".

How it works

• Dropped folders keep the same folder structure inside the ZIP. Photos, videos, PDFs and other already-compressed files are stored as they are, without compressing them again.
• Everything is held in the device's memory, so archives of several hundred MB or more may fail. Password-protected ZIP files and other formats such as 7z or RAR cannot be opened.
• Files are not sent anywhere outside the device.

Questions and answers

Why are the file names garbled after unzipping?

Older ZIP files sometimes store names in a regional encoding instead of UTF-8. Choose the right language under "File name encoding", then press "Save as ZIP with UTF-8 names" to get a new ZIP whose names show correctly on any computer.

How much smaller does a file get when zipped?

It depends on the file type. Text and documents shrink a lot, while photos and videos hardly shrink because they are already compressed. The sizes before and after are shown when the ZIP is made.

Can I extract all files at once?

No. Each file is saved separately with its "Download" button in the list.

Can it open a password-protected ZIP?

No. Password-protected files are marked "Password" in the list and cannot be downloaded.
