# Archive Viewer

See what is inside an archive before you unpack it with our Archive Viewer. Upload a ZIP, TAR or TAR.GZ file and get a table of every file, folder and link with its path, type, size and modification date, plus the number of files and the total size. The ZIP listing is read from the central directory without decompressing, so it is a fast and safe check for downloads, email attachments and backups.

## Frequently asked questions

### How do I see the contents of an archive?

Upload a ZIP, TAR or TAR.GZ file and click View Archive. You get a summary with the format, the number of files and folders and the total size, followed by a table of every entry.

### Which formats can the viewer read?

ZIP, including ZIP64, plain TAR and GZIP-compressed TAR files ending in .tar.gz or .tgz. The format is detected from the content. 7z and RAR archives are not supported.

### What does the table show?

Each row shows the path inside the archive, whether the entry is a file, folder, link or other special entry, the uncompressed size of files and the modification date in UTC. Folders and links have no size of their own.

### Are the files decompressed to build the listing?

For ZIP archives no file is decompressed, because the listing comes from the archive's central directory. A TAR.GZ archive has to be decompressed to read its headers, which is capped at about 50 MB.

### How large can the archive be?

The uploaded archive can be at most 10 MB and may hold at most 1,000 entries. Archives with more entries are refused with a message.

### Is the viewer safe for suspicious archives?

Yes. Nothing is unpacked to disk or run, and archives with absolute paths or .. segments, which could overwrite files elsewhere when unpacked, are refused with a message naming the entry.

### Can I view password-protected ZIP files?

Usually yes. ZIP encryption protects file contents, not the list of names, so the viewer can show the entries of most encrypted archives without the password.

### Why do the sizes differ from the archive size?

The listing shows uncompressed sizes, while the archive size is the size of the file you uploaded. The difference is what compression saved.

### How do I get the files out after viewing?

Use the ZIP Extractor for ZIP files or the TAR Extractor for TAR and TAR.GZ files. Both return the files as a ZIP download.

### Is the uploaded archive stored?

No. The archive is read in memory for this request and only the listing is returned.
