zip (MATLAB Functions)

Compress files into zip-file archive

Syntax

zip(zipfile,files)
zip(zipfile,files,rootdir)
entrynames = zip(...)

Description

zip(zipfile,files) creates a zip-file with the name zipfile from the list of files and directories specified in files.

zipfile is a string specifying the name of the zip-file. The .zip extension is appended to zipfile if omitted.

files is a string or cell array of strings containing the list of files or directories included in zipfile. Paths specified in files must be either relative to the current directory or absolute. Relative paths are stored in the zip-file, but absolute paths are not. Directories recursively include all their contents.

zip(zipfile,files,rootdir) allows the path for files to be specified relative to rootdir rather than the current directory.

entrynames = zip(...) returns a string cell array of the relative path entry names contained in zipfile.

Note The zip function does not preserve file permissions--file permissions in files are not maintained in zipfile.

Examples

Zip a File

Create a zip-file of the file guide.viewlet, which is in the demos directory of MATLAB. It saves the zip-file in d:/mymfiles/viewlet.zip.

file = fullfile(matlabroot,'demos','guide.viewlet');
zip('d:/mymfiles/viewlet.zip',file)

Zip the files guide.viewlet and import.viewlet and save the zip file in viewlets.zip. The source files and zipped file are in the current directory.

zip('viewlets.zip',{'guide.viewlet','import.viewlet'})

Zip Selected Files

Zip all .m and .mat files in the current directory to the file backup.zip:

```
zip('backup',{'*.m','*.mat'});
```

Zip a Directory

Zip the directory D:/mymfiles and its contents to the zip-file mymfiles in the directory one level up from the current directory.

```
zip('../mymfiles','D:/mymfiles')
```

Zip the files thesis.doc and defense.ppt, which are located in d:/PhD, to the zip-file thesis.zip in the current directory.

zip('thesis.zip',{'thesis.doc','defense.ppt'},'d:/PhD')
