But not all installers unpack files by default; some of them immediately begin installation. In this case it is quite difficult to trace the destination folder, but you can check shared directories for installed programs. The PDA communicates with the desktop PC through a synchronization program (ActiveSync). Go to the folder with this program and find the directory with the name of the file to be launched. It is also recommended to search the desired directory inside Program folders Files on your system disk. To open the search dialog, you need to press the combination Ctrl keys+ F.

In the window that appears, select the desired cab file and click the “Save” button. Do not forget to specify the directory for unpacking in the program settings of this type files. How simple

It is usually difficult for novice computer users to understand what a distribution kit (installation file) is and how it differs from the program itself. This causes many problems, let's use simple, clear examples to understand the purpose and differences between one and the other.
In order to install a program on a computer, you must have a distribution kit for this program, or otherwise called an installation file or installer. In fact, this is the same program, but in a form prepared for its installation, that is, it cannot be used until the installation is completed.
To install the program, you need to run the installation file; the installation wizard checks for the presence of required libraries and components and if everything is fine, he usually asks a few questions about the installation location and some settings and proceeds directly to the installation. Creates in in the right place file system folders and files with the program, makes necessary records in the registry. After the installation process is completed, you can use the new installed program, and the distribution can be removed so that it does not take up extra space on your computer’s hard drive.
Unpack the files into the specified directory. This command packs specified files into the installation and then unpacks them during the installation process.
Comment
If desired, you can specify comments for this command.
Compression type
Specify the compression algorithm that will be used for all files in the current group. The following options are possible:
DEFAULT- Compression based on LZ algorithms. This algorithm allows for very fast unpacking.
PPMD- PPMD compression. This algorithm provides excellent compression ratio, but the decompression time is equal to the packing time. Therefore, unpacking is not very fast. This compression algorithm was implemented and adapted for CreateInstall by Dmitry Shkarin.
STORE- Do not compress files.
Compression level
If you use DEFAULT or PPMD compression, the compression level can vary from 1 to 10. More high value means better compression, but longer time for packaging.
Solid compression
Checked => Information about already compressed files used for compression following files. This provides best degree compression on large quantities homogeneous files. Note that if you use PPMD compression, this feature may worsen compression on some files.
Source files (masks) or directories
File, mask or folder
Specify the file name (including full path) or directories on your computer that must be included in the installation. You can specify them in the selection window by clicking on the buttons on the right. If a directory is specified, it will be compressed with all its files and then created during the installation process.
C:\data\*.dbf C:\myapp\*.* C:\picture C:\files\myfiles.a??
Checked => recursive search for files in subdirectories.
Search files only
Checked => use the specified masks only to search for files.
Pack empty folders
Checked => take into account and add empty directories to the installation.
Ignore masks
You can define masks for excluded files. Masks must be separated by semicolons. These files will be ignored by the packer. You can use "*" and "?".
*.bak; temp*.dat
Unpacking options
Destination directory
Specify the directory where these files will be unpacked.
APPLICATION DATA PATH- Program folder in Application Data.
CDROM PATH- CD or DVD disc.
CUSTOM PATH- The path will be defined along with the file name.
INSTALL PATH - Main path installations.
SETUP FILE PATH- Path to the running installation file.
SYSTEM PATH- Windows system directory.
TEMPORARY PATH- Windows temporary directory.
WINDOWS PATH- Windows directory.
Unpack later- You can unpack these files into different directories using the command Unzip files.
Path is not default
Here you can specify any installation directory if you selected CUSTOM PATH above.
If the file exists
What to do if the file to be installed already exists.
Skip- do not write the file.
Write down- rewrite existing file.
Write down if newer- overwrite an existing file if the file being written is newer or has a larger version.
Ask- ask the user for permission to overwrite this file.
Ask if newer- ask the user for permission to overwrite only if the file being written is newer or has a larger version. Otherwise, the file entry will be skipped.
Comment! If a file needs to be updated, but it is occupied by the system or another application, then at the end of the installation the user will be prompted to restart the computer. Such files will only be overwritten after a reboot.
Additional options
Groupname => mydatafiles password => 15qwe67 unlog => on1 unlogfile => delete Xfilter => filtercmdproc allfolder => 1
If you unpack a lot of files, you can hide the installation path and file names in Dialog - Progress. This allows you to significantly increase the unpacking speed. To do this, set the value of the variable hidefiles equal to 1.
