|
---|
| 22 | # manifest of the files installed containing the relative paths, sizes and
|
---|
| 23 | # checksums of each files. When the program starts up, this manifest file is
|
---|
| 24 | # downloaded from the update server and is compared to the local one. Then the
|
---|
| 25 | # updated and new files are downloaded with names that are created by appending
|
---|
| 26 | # the checksum to the actual name, so as not to overwrite any existing files at
|
---|
| 27 | # this stage. If all files are downloaded, the downloaded files are renamed to
|
---|
| 28 | # their real names. On Windows, the old file is removed first to avoid trouble
|
---|
| 29 | # with 'busy' files. If removing a file fails, the file will be moved to a
|
---|
| 30 | # temporary directory, that will be removed when the program starts the next
