zip 3.0.0

CRAN release: 2026-06-10

  • zip(), zipr(), zip_append(), zipr_append(), zip_process(), and unzip() / unzip_process() now support password-protected archives using WinZIP AES-256, and other encryption schemes (#38).

  • zip_list() now reports an encryption column indicating the encryption scheme used for each entry (#38).

  • unzip() is now vectorized. If all arguments apart from zipfile, exdir and password are the default, then it unprocesses all files concurrently, using a thread pool. The size of the thread pool can be set with the zip_threads option or the ZIP_THREADS environment variable (#147).

  • zip_list() and unzip() now work directly on http:// and https:// URLs. They use HTTP range requests to download only the central directory and the requested entries, so listing or extracting a few files from a large remote archive does not downloads the whole file. If the server does not support range requests, they fall back to downloading the entire archive (with a warning). This requires the curl package (#39).

  • zip_list() and unzip() now report the Unix permission bits stored in an archive on Windows as well. Previously they always reported 700/600 on Windows, regardless of the permissions recorded in the ZIP file.

  • zip_list() and unzip() now report type == "directory" for directory entries whose Unix mode bits lack S_IFDIR but that are marked as directories by a trailing slash or the DOS directory attribute (e.g. archives created by zip() itself). Previously these were reported as "file".

  • zip() and unzip() now show a progress bar when the cli package is installed. For zip(), progress is byte-level, so large single files are tracked smoothly. For unzip(), progress advances once per extracted entry. Progress bars are (for now) opt-in via the ZIP_PROGRESS=true environment variable or the zip.progress option (#48).

  • unzip() now returns a data frame (invisibly) with one row per extracted entry, containing the same columns as zip_list() (filename, compressed_size, uncompressed_size, timestamp, permissions, crc32, offset, type) plus a path column with the absolute path to each extracted file on disk (#35).

  • zip_list() and unzip() now have an encoding argument for ZIP files with non-UTF-8, non-CP437 filenames (e.g. CP932/Shift-JIS on Japanese Windows). When encoding is set, filenames without the UTF-8 flag are decoded from the specified code page instead of CP437 (#101).

  • zip_append() and zipr_append() now replace existing entries when appending a file whose archive path already exists in the zip file, instead of creating duplicate entries (#111).

  • unzip() and zip_list() now correctly handle ZIP files with non-UTF-8 filenames (e.g. filenames encoded in IBM CP437, as created by many Windows tools). The filenames are converted to UTF-8 using the CP437 character map when the UTF-8 flag is not set in the ZIP entry (#103).

  • New keys argument to zip(), zipr(), zip_append(), and zipr_append(). It allows specifying custom paths for entries inside the archive, independently of their paths on disk (#50).

  • unzip_process() now probes falls back to using an R subprocess when the bundled cmdunzip executable cannot be started (#135).

  • Updated embedded miniz to version 3.1.1 (#122).

zip 2.3.3

CRAN release: 2025-05-13

  • zip_list() now has a type column, for the file type.

  • unzip() now correctly creates symbolic links on Unix (#127).

zip 2.3.2

CRAN release: 2025-02-01

  • zip_list() now returns a tbl object, and loads the pillar package, if installed, to produce the nicer output for long data frames.

zip 2.3.1

CRAN release: 2024-01-27

  • The zip shared library now hides its symbols (on platforms that support this), to avoid name clashes with other libraries (#98).

zip 2.3.0

CRAN release: 2023-04-17

  • zip now handles large zip files on Windows (#65, #75, #79, @weshinsley).

  • zip now behaves better for absolute paths in mirror mode, and when the paths contain a : character (#69, #70).

  • zip::unzip() now uses the process’s umask value (see umask(2)) on Unix if the zip file does not contain Unix permissions (#67).

  • Fix segmentation fault when zip file can’t be created (#91, @zeehio)

  • Fix delayed evaluation error on zipfile when zip::zip() is used (#92, @zeehio)

  • New deflate() and inflate() functions to compress and uncompress GZIP streams in memory.
