Added DIFAT sectors support #265

Closed max619 closed 1 year ago

max619 commented 1 year ago

I have tested it that way:

To my regular MSI file which is ~450 MB added 1GB file and packaged it, as a result I got a MSI file that is larger then 1.45 GB. Then signed it, installed and checked hash sum of that large file, it matched the original. Also I tried to verify checksum with osslsigncode, verification passed too.

Unfortunately, I was not been able to create MSI file with more then 1 DIFAT sector, so case with 2 or more DIFAT sectors is not tested.

Related to the issue #244

1 DIFAT sector can address 1024 FAT sectors, each referencing 1024 sectors of 4096 bytes, so a size of 4GB. A second DIFAT sector should appear with a file of 4.43GB or more.

I'm afraid we don't support files larger than 4GiB for now.

The Windows Installer does not support Package files larger than 2GB in size. The installation will likely fail with an unexpected error.
