Hi, I've stumbled upon a 7.0 incompatibility with regards to how file names are treated. In 6.1, I can use Strings and FileLocators interchangeably to create and read Zip archives. That's because StandardFileStream does the magic behind the screnes. In 7.0, StandardFileStream has been deprecated, and "File openForReadFileNamed:" is used instead. That method does not handle FileLocators, so code that uses FileLocators to open Zip archives ceased to work. What's the preferred solution? It strikes me as illogical that objects which were made to reference files can't be used to reference files in these contexts. However, there may be a conscious design decision behind this change that's just not obvious to me. Cheers, Hans-Martin -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
