Installation Files

Unpacks files into specified directory. This command compress specified files into the setup file and then unpacks their during the installation process.

Description

Optionally, you may add comments here describing the purpose of this element.

Compression Type

Specify the compression algorithm to be used for all files in the current group. The following options are possible:
DEFAULT - Gentee's compression algorithm ( similar to other LZ algorithms ). This algorithm provides very fast unpacking.
PPMD - PPMD compression algorithm. This algorithm provides excellent compression ratio, but unpacking time is the same as the compression time. The decompression is slow. This compression method has been developed and adapted for CreateInstall by Dmitry Shkarin.
STORE - Do not compress files. Use this for files that are already compressed.

Ratio

If you use the DEFAULT or PPMD compression, the compression ratio may vary from 1 to 10. The higher compression ratio provides smaller file size, but slows down the compression process.

Solid Compression

Checked => Information about the files already compressed is used for compressing every successive file. This provides better compression ratio if you have a number of homogeneous files. Please note that if you use the PPMD compression, enabling this option may worsen the compression ratio for heterogeneous files.

Source files (wildcards) or directories

File, wildcard or folder

Enter a filename (including path and drive designation) or a folder on your computer, which should be included in the setup, or use the browsing buttons to select them. If you enter a directory, it will be packed together with all of its files and then re-created on the target computer.

C:\data\*.dbf 
C:\myapp\*.* 
C:\picture 
C:\files\myfiles.a??

Recursive Search

Checked => enables the recursive search in all subdirectories.

Seek Files Only

Checked => uses the specified wildcard for seeking the files only.

Pack empty folders

Checked => adds empty folders into your setup.

Ignore wilcards

You can specify wildcards of excluded files (by semicolon). These files will be ignored during the packing process. You can use '*' and '?' characters.

*.bak; temp*.dat

Unpacking options

Destination folder

Choose the installation path on the user's computer where files are to be unpacked.
APPLICATION DATA PATH - Program subfolder in Application Data folder.
CDROM PATH - CD or DVD drive.
CUSTOM PATH - The path must be defined in the filename control.
INSTALL PATH - Default installation path.
SETUP FILE PATH - The path where setup executable file is run.
SYSTEM PATH - Windows system directory.
TEMPORARY PATH - Windows temporary directory.
WINDOWS PATH - Windows directory.
Unpack later - You can unpack these files later with the Unpack Files command.

Custom Path

Here you can specify any destination path, if CUSTOM PATH is selected in the Destination folder field.

If File Exists in Destination

What should be done if a file being installed already exists on user's hard drive.
Skip - do not extract the file.
Overwrite - overwrite the existing file.
Overwrite if newer - overwrite the file only if the file is newer or has a later version than the already existing one.
Ask - prompt the user to select an appropriate action.
Ask if newer - request directions from user only if the file is newer or has a later version than the already existing one. Otherwise, the file will be skipped.
Notice! If a file must be updated but is locked by the system or by other applications, at the end of installation, the user will be asked to reboot the computer. Such files will be updated after the reboot.

If Condition

You can specify a condition that should be met for the action to be performed. See If Condition for Wizard for more details. If the condition is FALSE then the command is skipped. See How to use If Condition for more details.

Additional settings

groupname - specify the name of the group if you want to unpack these files with the Unpack Files command later.

groupname => mydatafiles
