Get File Information

This action retrieves a specific property you want to know about a given file and stores it into a variable.

Name	Description
fiGetFileCRC32	Computes the 32-bit cyclic redundancy checksum (CRC-32) of the file. This command is useful if you want to check whether a file is not altered. May require time for large files (several GB) depending on the computer configuration. >> Use the "Tools\|Compute CRC-32 of a file" menu command in Paquet Builder to get the CRC-32 of an original file, then use this action to calculate the one of the same file (once extracted). Using a Conditional If block, you can check whether the file was successfully extracted or not.
fiGetFileSize	Obtains the size in bytes of the specified file.
fiGetFileVersionLS	If the file to analyze contains a resource version block, then the package retrieves the least significant 32 bits of the file's binary version number.
fiGetFileVersionMS	Retrieves the most significant 32 bits of the file's binary version number.
fiGetFullFileVersion	Converts the file's binary version number to the traditional format "X.X.X.X" you can see in the "File Properties\|Version" tab in Windows Explorer.
fiGetProductVersionLS	Retrieves the least significant 32 bits of the binary version number of the product with which this file was distributed.
fiGetProductVersionMS	Retrieves the least significant 32 bits of the binary version number of the product with which this file was distributed.

The last 4 options are used to compare file version information: you can determine whether a file already present on the destination computer is more recent or not (and consequently whether it should be overwritten or not). This has to be used with the conditional variables and a Conditional If block for instance.
