Usage: WiFile.exe package.msi /l [filename,filename2,...] Usage: WiFile.exe package.msi /x [filename,filename2,...] Usage: WiFile.exe package.msi /u [filename,filename2,...] Lists (/l), extracts (/x) or updates (/u) files in an MSI or MSM. Files are extracted using their source path relative to the package. Specified filenames do not include paths. Filenames may be a pattern such as *.exe or file?.dll
The most powerful use of WiFile.exe is to do a round-trip update of files in a compressed MSI/MSM package. It works like this:
- Extract specific file(s) or all files from the package: WiFile.exe package.msi /x *
- The files are now expanded into their directory structure. You can edit/update the files however you like.
- Update the package with the changed files: WiFile.exe package.msi /u * This also updates the file metadata in the MSI including the file version, size, and hash.
Also works with packages that have multiple and/or external cab(s).
