SparkZip won't unpack Zip files that use Implosion method
| Reported by: | Stuart Painting (5389) | Severity: | Normal |
| Part: | RISC OS: Application | Release: | |
| Milestone: | Status | Open |
Details by Stuart Painting (5389):
The Zip “Implosion” compression method was present in early versions of SparkFS, but the ability to create Zip files using that method was removed in SparkFS 1.31 (1997). The ability to unpack Zip files using the “Implosion” method was retained.
Starting with SparkZip 1.50 (SparkFS 1.51), Zip files using the “Implosion” method now give a series of “Bad archive” errors.
Importing the SparkZip 1.44 module from SparkFS 1.46 will allow SparkFS 1.56 to unpack these Zip files, which indicates that the problem lies in the SparkZip module.
