CSDb compression
Hiya,
does it make sense to compress single d64 files when posting an entry to save space or are the files stored compressed on fileserver/in database anyway.

never heard of webservers who have autocompression of raw unknown formats. so dont think so. :)
only if the disk on webserver has autocompression (ala windows compressed volume etc.)
my guess is , no. |

Please, if you don't have to, don't compress files. It makes it so convenient for click/run or click/drag/drop/run ;)
I think it only makes sense for multi-disk releases, just to make sure that people download complete release. |

also in case of fail, and datarescue, compressed data = risk to loose it. |

not quite what didi asked about though :) (but it makes the question about zipping or not zipping d64s kinda irrelevant, indeed) |

Quoting Dididoes it make sense to compress single d64 files when posting an entry to save space Yes, if only because ZIP and other archives retain file timestamps which the uncompressed D64s don't.
Quoting wackeePlease, if you don't have to, don't compress files. It makes it so convenient for click/run or click/drag/drop/run ;) gzip'd D64s are just as "convenient" in this way as uncompressed ones, at least with VICE. |

if only ppl wouldnt rip apart spreaddisks and copy each release into a new d64, then it'd be a good point :) |

As if there would be so many new releases that unzipping becomes uncomfortable :-) |

As others have commented, uploading compressed single disk images is completely pointless due to network transport compression (and also transparent compression in filesystems and databases).

Yes, and there, we'd be better off with some container format as seen on commercial C-64 emulators (see http://www.retroplatform.com/kb/15-122), which is basically a standard archive (usually compressed, think tarball or zip) with all required disk images and a manifest file (with meta-data like emulator settings), and possibly also other stuff like screenshots and .sid files, scrollers in plaintext and whatnot. Such a scheme would also make disk-changing in emulators and modern 1541 replacements a breeze.
It's long overdue for our community to define an open standard similar to that.
Are there any plans to support something like that in VICE, once it exists, groepaz? |

Good to know. I usually compress them but since it's not really needed I won't do it anymore. |

Just recently, it's obvious that Modul Utility V1.3, Edit Memory, and Save Program are all the same disk with all files but one scratched. What a waste of time! The uploader could've uploaded the original disk image for one database entry, then copied and pasted the URL into the others. |

personally i love it when someone makes a "clean" d64 and then breaks the release in the process =P |
