paketifailid

Paketifailid, in Estonian, refers to archive files—single files that bundle multiple separate files and folders into one container. They are often compressed to reduce size and simplify distribution, storage, and transport. Archives preserve directory structure and metadata such as timestamps and permissions.

Common formats include ZIP (.zip), TAR (.tar), and variants such as tar.gz (.tar.gz or .tgz) and tar.bz2 (.tar.bz2). Other widely used formats are 7z (.7z) and RAR (.rar). Tar is an archiving format that does not compress by itself; compression is provided by external programs like gzip or bzip2. ZIP, like many formats, combines archiving and compression in a single format. File extensions may hint at the format but are not always definitive.

Uses of paketifailid include distribution of software and documents, backups, data packaging for transfer, and packaging for software repositories. Archives can protect multiple files with password encryption in some formats, and can include digital signatures or checksums for integrity and authenticity.

Extraction and creation are performed with various tools. Creation tools bundle files into an archive, and extraction tools unpack them. Common tools include unzip, tar, 7-zip, WinRAR, and graphical file managers with built-in support. On Linux, commands such as tar -czf file.tar.gz directory are typical; on Windows, graphical interfaces are commonly used.

Security and considerations: archives may contain malware, and password protection adds security only if strong cryptography is used. Always verify integrity with checksums or digital signatures when possible. Compression is most effective on text or redundant data; already compressed files may gain little size reduction.
