Is zip compression lossless?

I have external hard drives to which all of my video files are saved.  However, they are not always kept off-site.  One of the less expensive online backup services zip files stored with them.  A source at http://www.animemusicvideos.org/guides/avtech/video3.htm , said that the ZIP is a lossless compression, but wanted confirmation here before making a decision on the use of their services.  Thanks for your help.

Yes, the ZIP is lossless. Now, with the video/still active, i.e. AV files, JPEG, etc., don't expect much compression with closing SLIDE, or any archiving program. Best for data burning DVD, or pick up some external HARD drives

  • How can I get rid of the zipped compressed files?

    Whenever I try to make a new folder it tells me to make a zipped compressed folder and I don't know how to stop it. He began doing this a few days ago and I did not install anything. I would go back to the default value for new records instead of zipped compressed folders.

    You have lost the ability to create a new "folder".  You have installed chrome? It's looking like a recent update of chromium may be the cause. Here are two patches.

  • LR 4.3: How to save * existing * Tiff with Zip Compression

    Dear all,

    -J' using LR 4.3 on a windows 7 x 64 PC.

    -J' use a catalog for each wedding/event/shoot.

    -J' I import all my images as CR2 or DNG and work with those files in LR and Photoshop CS6.

    -Once I finished making changes on a marriage, I find myself with, for example, 300 16-bit uncompressed Tiff images in a dozen different files (I shoot big 600 pax + marriages sometimes).


    -I want: Re-save/overwrite all these images as Tiff 8 bit images with ZIP compression.

    How can I do this?

    -J' tried to select all images and exporting 8 bit Tiffs Zip with the tab replace originals without selected warning. However I get the error that the file already exists and LR can do nothing about it.

    -J' tried to create an Action in Photoshop, but there are two problems: 1) photos are spread over several files and selecting each via file > batch > controller means the process requires manual intervention to reselect TIFF of the next file - I want to hit the action, go to lunch and come back to find ALL registered. (2) the action is outside the LR and I would like rather to avoid mistakes of "metadata has changed outside ' even though this is not really a biggie.

    Why not just save the images as TIFF Zip initially? I use a number of freelance retouchers, many complain that the compression process slows down their workflow initial (slower material).

    I would be very grateful for any ideas.

    (and yes - the space is considerable, there where I live the memory is still not cheap enough!)

    Thanks in advance...

    Have you determined the steps you want for a single photo in Photoshop?

    You have an action of these steps that does what you want in a folder?

    It would be wise to leave things as a 16 - bit where the layer blending options change too, but you can confirm one way or the other by testing with a complicated overlay of the edges carefully to feather situation and make sure that nothing looks bad after you convert to 8-bit.

    It seems it would work to use Bridge to select the whole lot of hair in a marriage to compress and eventually convert to 8-bit.  With the help of your file (s) example:

    Bridge point to the Jack and Jill marriage file, set the view to display items in subfolders, define the filtering in TIF, leave the bridge find all hair and then do a Select All on them and choose tools / Photoshop / lot... then indicate your photo-simple action and make sure that the source is bridge and whatever other parameters are required and let it go.

    You would like to experiment and perfect your batch processing on a copy of the records so it wouldn't destroy the real business until you were sure it was working.  It is possible that some thing would not work because you substitute on top of photos or make several subfolders or something else - I'm not much of an expert of action PS, but it should be relatively easy to check if it would work or not.

  • Internal (zip) compress possible content table?

    I have a database with about 20 tables that contain a large amount of data.
    This database is rarely used (once for a few hours every two weeks).

    When I generate scripts SQL (with INSERTs) to recreate the data on the size of the file will be huge (about 30 GB!)

    When I zip compress these SQL scripts they will be reduced to about 20 MB!

    So the relationship between the size of the data uncompress and compressed is remarkable 1:1500

    In order to avoid a waste of space disk, I think to let Oracle compress the data internally as well.
    The final solution should work something like:

    Start Oracle 1 services.)
    (2.) to connect to the database
    3.) tell Oracle (by SQLplus command): "Hey Oracle, unpack internal all tables".
    tab1, tab2, tab3,..., t20
    4.) certain operations SQL SELECT, UPDATE,...
    5.) tell Oracle (by SQLplus command): 'Hey Oracle, now re - compress all tables internally. "
    tab1, tab2, tab3,..., t20 again
    6.) disconnection from the database
    Services stop Oracle 7).

    OK, I know of compression and decompression will take a few minutes, but it is acceptable to me.

    Is - it somehow possible?

  • How can zip compressed file - I add a password?

    In Windows XP, it was possible to send a file to the compressed folder, and then in the folder go to file, add password and password protect. In Windows 7, the option to add password is no longer available, how a password can be added in the zip file?

    The ability to natively password - protect a zipped file was removed from Vista and Windows 7. Don't ask me why; I have no idea. If you want to protect a zipped file, you will need to get third-party compression software that supports this. WinZip can do but is commercial. Possibly 7Zip can do and this program is free.

  • Is better zip for compression of the image?

    I asked a question on jpeg file size in the InDesign forum. I have a file of about 40 MB, which records in max quality JPEG in Photoshop at around 12 MB. Once it goes into InDesign and fate of the other end as part of a PDF document, the file size is 3 MB.

    I believe data are disappearing, but one answer seems to indicate that zip compression is now used increasingly as a jpeg.

    I always thought that it was worth zip compression of files such as jpg, mp3, etc. that have already been compressed and that the only way InDesign could hit my JPEG files up to a fraction of their size was recompression them in lower-quality JPEG format?

    Gator, in my opinion, Amy had already done all the required exams:

    Any image of the source, compressed or not, is in InDesign, considered as the

    "best available source. A JPEG file must be decompressed. The story disappeared.

    Quite clear - an image placed in InDesign can be cropped or scaled, which

    destroy all JPEG-history.

    This "best available source" is then used in the export to PDF format with new

    features of compression and downsampling, perhaps with new color settings.

    In simple terms: a Photoshop JPEG can be transferred by InDesign

    into a PDF file directly.
