    still setting up my resurrected computer.

    i would like to claim some disk space.

    i have about 10 gigs of jpegs

    and 35 gigs of audio shiurim

    that i only access occasionally.

    would like to buy winzip and zip them

    can anyone estimate, ballpark, how much 45 gigs will shrink after zipping?

    I don’t know, but how about buying an external hard drive?

    I don’t think mp3s save much when zipped, agree with SJS’s suggestion.

    Hi.

    My experience has been that media files (photos, audio and video) don’t compress much, if at all.

    The .jpg format in particular is already considered “lossy” due to its compression.

    Compression is most effective for text files (both “plain” .txt and word processor documents), as well as spreadsheets.

    Please don’t waste money on winzip.

    First of all, 7-zip is free and is better than winzip in almost every way.

    Secondly only text based files compress significantly.

    Jpegs, audio and video files all can’t be compressed much at all as they are all compressed formats to start with. So you won’t save almost any space through zipping them.

    I fully agree with SJSinNYC that an external hard drive is a much better eitzah for you here.

    from the responses here i was able to google more accurately.

    i found out:

    1.in general 7-zip is probably much better than winzip as todros said

    2. for jpeg files winzip Vers. 12-15 has a special algorithm that compresses them about 20%. i dont know if 7-zip does this.

    3. i wasnt able to get any specific info on mp3 files except that they dont compress much as was said

    get an external drive – a 2TB one can be gotten these days for 70-80 if you find a good deal – you can get two and have two copies of it and never run out of space and have them organized for when you want them

    it is clear to me there is an external drive conspiracy in the CR. i dont know the motivation. probably some kickbacks from icots external drive company.

    Are the audio files already compressed? If not you can save alot of space by converting them to MP3 or OGG.

    I looked into it and it seems like Winzip can compress jpegs about 20% better than 7-zip.

    I didn’t know that.

    MP3’s are already compressed to the max and no compression method in common use will make a difference.

    what i found is that winzip can compress jpegs 20% from their non compressed state

    it didnt say anything comparing this to 7zip

    maybe 7zip can do even better

    seeallsides-

    That’s a great price.

    Just a suggestion – posting the URL to the actual item can be helpful (and save time).

    I did research and found that only winzip can compress jpegs that much.

    7-zip’s compression is way better for almost all other (compress-able) file types.

    By the way, what did you do le’maaseh?
