The Contents command reads the index of a zip file archive and returns a list of strings representing the names of the files contained in that archive.

The list returned does not include the zip file name. To read each member, L[i] returned in the contents list, use FileTools:-Compressed:-ReadFile( L[i] in zipfilename, options ).

This command only works on zip files. Files in gzip format do not contain sub-files.

The filename option must be a string, not an open file handle, and not a subfile in zipfile member reference.

$\mathrm{zipfile}≔\mathrm{FileTools}\left[\mathrm{TemporaryFilename}\right]\left(\mathrm{FileTools}\left[\mathrm{JoinPath}\right]\left(\left[\mathrm{FileTools}\left[\mathrm{TemporaryDirectory}\right]\left(\right)\,''Ziptest-''\right]\right)\right)$

$\mathrm{zipfile}≔''/tmp/mpldoc20/Ziptest-yYoYxV9R''$

FileTools[Compressed][WriteFile]("first" in zipfile, "a 1st file");

$10$

FileTools[Compressed][WriteFile]("second" in zipfile, "a 2nd file");

$10$

$L≔\mathrm{FileTools}\left[\mathrm{Compressed}\right]\left[\mathrm{Contents}\right]\left(\mathrm{zipfile}\right)$

$L≔\left[''first''\,''second''\right]$

[seq( FileTools:-Compressed:-ReadFile(F in zipfile, string), F in L)];

$\left[''a\; 1st\; file''\,''a\; 2nd\; file''\right]$

$\mathrm{FileTools}\left[\mathrm{Remove}\right]\left(\mathrm{zipfile}\right)$

The FileTools[Compressed][Contents] command was introduced in Maple 18.
