R: Uncompress 'zip' Archives

unzip {zip} | R Documentation

## Uncompress 'zip' Archives

### Description

`unzip()` always restores modification times of the extracted files and directories.

### Usage

    unzip(zipfile, files = NULL, overwrite = TRUE, junkpaths = FALSE, exdir = ".")

### Arguments

`zipfile` | Path to the zip file to uncompress.
`files` | Character vector of files to extract from the archive. Files within directories can be specified, but they must use a forward slash as path separator, as this is what zip files use internally. If `NULL`, all files will be extracted.
`overwrite` | Whether to overwrite existing files. If `FALSE` and a file already exists, then an error is thrown.
`junkpaths` | Whether to ignore all directory paths when creating files. If `TRUE`, all files will be created in `exdir`.
`exdir` | Directory to uncompress the archive to. If it does not exist, it will be created.

### Permissions

If the zip archive stores permissions and was created on Unix, the permissions will be restored.

### Examples

    ## temporary directory, to avoid messing up the user's workspace.
    dir.create(tmp <- tempfile())
    dir.create(file.path(tmp, "mydir"))
    cat("first file", file = file.path(tmp, "mydir", "file1"))
    cat("second file", file = file.path(tmp, "mydir", "file2"))

    zipfile <- tempfile(fileext = ".zip")
    zip::zip(zipfile, "mydir", root = tmp)

    ## List contents
    zip_list(zipfile)

    ## Extract
    tmp2 <- tempfile()
    unzip(zipfile, exdir = tmp2)
    dir(tmp2)
