Unzip compressed files

Not only can it fully decompress files in many different formats, it also supports compressing pictures, documents, PDF and other folders, compressing your files to the smallest size, and can add compression password for compressed files to protect your privacy. Small size, fast speed, and can also customize the source file after decompression or compression is completed, saving you resource space and bringing you an efficient and convenient user experience!

If a file already exists, skip the extraction of that file without prompting. By default unzip queries before extracting any file that already exists; the user may choose to overwrite only the current file, overwrite all files, skip extraction of the current file, skip extraction of all existing files, or rename the current file. File comments are created with the -c option of zip , or with the -N option of the Amiga port of zip , which stores filenotes as comments.

This is a dangerous option, so use it with care. Many multi-user operating systems including PTC MKS Toolkit on Windows provide ways for any user to see the current command line of any other user; even on stand-alone systems there is always the threat of over-the-shoulder peeking.

Storing the plaintext password as part of a command line in an automated script is even worse. Whenever possible, use the non-echoing, interactive prompt to enter passwords.

And where security is truly important, use strong encryption such as Pretty Good Privacy instead of the relatively weak encryption provided by standard zipfile utilities. Ordinarily unzip prints the names of the files it's extracting or testing, the extraction methods, any file or zipfile comments that may be stored in the archive, and possibly a summary when finished with each archive.

The -q[q] options suppress the printing of some or all of these messages. Since all PC operating systems allow spaces in filenames, unzip by default extracts filenames with spaces intact e.

This can be awkward, however, since MS-DOS in particular does not gracefully support spaces in filenames. Conversion of spaces to underscores can eliminate the awkwardness in some cases. This option is mainly provided for debugging purpose when the fairly new UTF-8 support is suspected to mangle up extracted filenames.

The handling of filename codings within unzip falls back to the behaviour of previous versions. See -L above. VMS files can be stored with a version number, in the format file. On file systems that limit filenames to particularly short lengths, the version numbers may be truncated or stripped regardless of this option. Currently, UnZip uses the same pattern matching rules for both wildcard zipfile specifications and zip entry selection patterns in most ports.

In most cases this will require special system privileges, and doubling the option -XX under NT instructs unzip to use privileges for extraction; but under Unix, for example, a user who belongs to several groups can restore files owned by any of those groups, as long as the user IDs match his or her own.

Note that ordinary file attributes are always restored--this option applies only to optional, extra ownership info available on some operating systems. It is not clear under what conditions this would ever be useful anyway. The default is to treat them as file types. By default, volume labels are ignored.

This safety feature new for version 5. To achieve this, it is necessary to set the extraction target folder to root e. Use this option with extreme caution. Generally, this allows to embed ASCII control characters or even sophisticated control sequences in file names, at least on 'native' Unix file systems.

However, it may be highly suspicious to make use of this Unix "feature". Embedded control characters in file names might have nasty side effects when displayed on screen by some listing code without sufficient filtering. And, for ordinary users, it may be difficult to handle such file names e.

Therefore, unzip applies a filter by default that removes potentially dangerous control characters from the extracted file names. The default is to exploit the destination file system, preserving case and extended file name characters on an ODS5 destination file system; and applying the ODS2-compatibility file name filtering on an ODS2 destination file system.

This can be done with any option, but it is probably most useful with the -a , -L , -C , -q , -o , or -n modifiers: make unzip auto-convert text files by default, make it convert filenames from uppercase systems to lowercase, make it match names case-insensitively, make it quieter, or make it always overwrite or never overwrite files as it extracts them.

For example, to make unzip act as quietly as possible, only reporting errors, one would use one of the following commands:. Environment options are, in effect, considered to be just like any other command-line options, except that they are effectively the first options on the command line. For instance, to override one of the quiet-flags in the example above, use the command. The first hyphen is the normal switch character, and the second is a minus sign, acting on the q option. Thus the effect here is to cancel one quantum of quietness.

To cancel both quiet flags, two or more minuses may be used:. This may seem awkward or confusing, but it is reasonably intuitive: just ignore the first hyphen and go from there.

It is also consistent with the behavior of Unix nice. The timezone variable TZ should be set according to the local timezone in order for the -f and -u to operate correctly. See the description of -f above for details. This variable may also be necessary to get timestamps of extracted files to be set correctly. Settings are:. When this variable is unset or it is set to a value other than those listed earlier, the default ANSI character set is used. However, since spring , US export restrictions have been liberated, and our source archives do now include full crypt code.

As noted above, the -P option may be used to supply a password on the command line, but at a cost in security. The preferred decryption method is simply to extract normally; if a zipfile member is encrypted, unzip will prompt for the password without echoing what is typed. The correct password will always check out against the header, but there is a 1-in chance that an incorrect password will as well.
