Spark archives are 'garble' or DES. > <Snip> To Dave Symes From what David has said (and I have snipped) it would seem to me that your best solution is to unZip (or unSpark?) in RISC OS (either using native RISC OS hardware or an emulator) and then zip them back up in RISC OS using the Zip option of !SparkFS. The RISC OS Zip is (as David says) standard and will unzip in Windows 7 and Windows 8 without any extra software. I have a vague recollection that I had to use something to unzip in Windows XP - but it might have been an earlier Windows. If you don't have VRPC then either Red Squirrel or RPCEmu can be used as a RISC OS emulator. I have written articles for Archive about installing Red Squirrel and RPCEmu on a Windows machine (complete with sets of files which enable you to install Red Squirrel or RPCEmu within 5 minutes) - but only the first of these has been published yet. I do have the other articles in PDF format and the files for the 5 minute install (contained in zips) if you would like them. Gerald N�����r��z�칻�&ނ�h��i��0���zX���+��b���j���)e�x
