wow.. that is a though question...quality is getting worse these days ;-)

 

let's see.. if you an MSI and a lot of files/folders you could guess that this is an uncompressed one.. 

If the MSI installs standalone successfully means compressed.

You can also check the media table to see if there are entries in that table that refer to .cab files .. meaning  (#) Single / Internal Compressed or External Compressed.

See jaybee's answer: if it's a standalone MSI then it has been compressed, if it's an MSI along with more files required for installation (usually CAB files) then it is most likely uncompressed. The problem is we don't know what MSI you are asking about so if you could tell us the application name or a link to the MSI it would be extremely helpful.

  • //if it's an MSI along with more files required for installation (usually CAB files) then it is most likely uncompressed.//

    If the msi has any .cab files which are required for the installation to be sucessful, then it is also compressed but externally.. .cab file is compressed format..

anymore answers... what?  why not do a deepdive in the technology called Windows Installer?   Your question is the first topic in any Repackaging training...  so you are completely new in the industry I presume without any training then?

  • I think they are lot more than what you say Mr. Jaybee. Uncompressed msi's will be a size in KB while compressed msi's can be in MB's.
  • No...there are not.. there are 3 types: MSI with CAB inside,MSI with CAB outside and Uncompressed.. and uncompressed MSI's can still have couple of MB's in size..

    UNcompressed MSI can still have lot's of data in the binary table..
