Description

Compresses files to an archive.
Supports various compression algorithms and encryption.
The archive usually should not contain the absolute paths of the files, so we need a base path and relative to that base path the list of files and folders to zip.

Examples

Compression examples:

# list of files in the folder to archive
Set Variable [ $list ; Value: "minitar.c¶simplebar.rbp¶test/other.txt" ]

# write zip file with password
Set Variable [ $r ; Value: MBS( "Archive.Compress"; "zip"; "deflate"; "/Users/cs/Desktop/minitar.zip"; "/Users/cs/Desktop/"; $list; "zip:encryption=zipcrypt"; "secret password" ) ]

# Write bzip2 compress tar file:
Set Variable [ $r ; Value: MBS( "Archive.Compress"; "ustar"; "bzip2"; "/Users/cs/Desktop/minitar.tar"; "/Users/cs/Desktop/") ]

# and write zip with aes encryption to container file:
Set Variable [ $r ; Value: MBS( "Archive.Compress"; "zip"; "deflate"; "minitar.zip"; "/Users/cs/Desktop/"; $list; "zip:encryption=aes128"; "secret password" ) ]
Set Field [ Archive Read::Container ; $r ]

Compress with UTF-8 file names:

MBS( "Archive.Compress"; "zip"; "deflate"; "C:\Users\Christian\Desktop\test.zip"; "C:\Users\Christian\Desktop"; "Bücher"; "hdrcharset=UTF-8" )

Compress content of logs folder on server:

# the path to logs folder
Set Variable [ $folder ; Value: "/opt/FileMaker/FileMaker Server/Logs" ]
# query list of files
Set Variable [ $list ; Value: MBS( "Files.List"; $folder) ]
# where to store the zip file:
Set Variable [ $ZipPath ; Value: MBS( "Path.AddPathComponent"; "/tmp"; "test.zip") ]
# and now zip these files:
Set Variable [ $archive ; Value: MBS( "Archive.Compress"; "zip"; "deflate"; $ZipPath; $folder; $list; "compression-level=9¶hdrcharset=UTF-8") ]

Compress a file in a let statement:

Let([
filename = "test.jpg";
SourcePath = MBS("Folders.UserDesktop");
DestPath = MBS("Path.AddPathComponent"; MBS("Folders.UserTemporary"); "test.zip");
r = MBS( "Archive.Compress"; "zip"; "deflate"; DestPath; SourcePath; filename; "zip:encryption=zipcrypt¶hdrcharset=UTF-8"; "12345" )
];r)

Compress with hashed password:

Let([
    filename = "test.jpg";
    password = MBS( "Hash.SHA256"; "testing" ) ;
    SourcePath = MBS("Folders.UserDesktop");
    DestPath = MBS("Path.AddPathComponent"; MBS("Folders.UserTemporary"); "test.zip");
    r = MBS( "Archive.Compress"; "zip"; "deflate"; DestPath; SourcePath; filename; "zip:encryption=zipcrypt¶hdrcharset=UTF-8"; password)
];r)
