do I really want to compress all my data?

Hello

I'm a peasant total techno and was trying to find out how much space was left on my macbook pro 2009.  In the finder, I saw "compress data" and thought that I remembered how to seller by recommending day to do so.  I clicked it, and my computer is making its way through 183,59 GB of data compression, which according to her, will take 5 days!  When I tried a google search, I came across a lot of complicated things that sounds like you should be only compress one file at a time.

While we are there, please can you me how do I know how much space is left on my computer?

Thanks a lot and it's okay if you roll your eyes.

Hi Dana,

You compress your entire hard drive? Or only some data on the hard drive folders?

Compression of data such as pictures, documents, pdf files, and other similar files is perfectly OK!

A file is made up of a bunch of metadata. Metadata is simply data about data. Well, there is some metadata is just useless in a file and there is no advantage. With compression, the file gets processed and been ejected from some of its attributes and metadata which translates to a much smaller file size.

However, there are some data that you don't want to compress. It comes to binary files that build the operating system (OS). If you plan to compress these file types, then corruption is likely to occur or may occur. When data compression, make sure that you can do without affecting your operating system files.

The reason why your compression takes so long is that you MOST likely have a disk speed is very low. Depending on your model laptop and the year, you most likely have a tough guy who has a speed of 5400 revolutions per Minute (RPM). This is... the magnetic disks inside the hard drive that revolve around a single PIN for read and write data. Low RPM train speed slow drive, which slows EVERYTHING down. * And to emphasize, if your drive is old and has a lot of reads/writes that took place during his life, so the speed of the discs degrade. This is what we call performance degradation.

In your scenario, I guess you have a slow drive, low RAM and a processor low range. Given these factors, it would take time to process and compress all data on your drive.

I suggest you kill the compression operation. Compression is really intended to those who is EXTREMELY low on disk space and they have no choice OR you have pure RAW data which can slow down operations in an application, you are working with, in which case compress you the data to remove some of that unnecessary metadata.

In the future, when you get a new machine, it is preferable to an installation on your disk compression before starting to use your machine. The data will be then get compressed by increments, rather than in a single session, which takes a lot of time.

I hope this helps.

Thank you

Mark

  • Replacement of the main computer, don't want to lose all the data synchronized.

    I use Firefox Sync with multiple devices at work and at home. My main computer, which is the original pc all data from first and I use to add new devices, is my work laptop. I'm being transferred across the country and no longer have this laptop.

    I need somehow put up my home pc or my new laptop to work as the new main computer, but I don't want to lose all data. Should I export all the data from the laptop the existing work and import it on the new pc, then installed Sync all over again on my other devices (Mercury browser for iphone and ipad)?

    Hello, first of all please create a backup of your profile of your work pc folder, so that you have your data available in all cases: back up and restore the information contained in the profiles of Firefox

    I do not think that there is something like a 'primary' feature in your accounts sync - all devices need to be at the height, you can simply delete your old laptop to sync & add the new laptop to the account:
    Go to firefox > options > tab sync on your old laptop. Please make sure you as your user name, password of the account and the recovery key is known to you (you can access the recovery key under 'manage accounts' "-write it down if you haven't done so already '), then click on separate device in the Synchronize tab.

    You can then add your new laptop to work on behalf of sync existing either by coupling a device while you're close to your pc at home or with your user account, password and recovery key.

    I have been in support of Verizon, but am no where.  I came by the Apple Support page first, but the problems they had to choose, was not there.  So, I finally did here.  Please, could someone at least tell me where to find the information needed to get rid of the 5?  It would be highly appreciated.

    Subscription plans are your least expensive option on an annual basis, but do not continue to pay each year in order to continue using them.  The alternative is to buy CS6 which is much more costly in terms of what you pay in the year (day).,... almost all of the costs.

  • Compress all the existing table ain dat

    Hello

    We use oracle 11.2.0.3 and wish to evaluate the performance of compression in terms of reduction of time takes to reports aganis the tables run.

    Had a quick serach and can see alter table compress but speaks only of data inserted/updated updated after the operationexecute of compress is compressed.

    Do not want to have to create a separate, compressed table and replace other table with that.

    Is it possible to compress all the existing dat aof existing table?

    Also could what kind of performance gain magntitudes we expect performance report using the compression compared to identical but uncompressed tabel?

    Also it is a data warehouse and the large fact table already has the default compressed index bitmpa.

    Depending on your hardware, you can use alter table move and change the index on a table of size fairly decent rebuild in less than 10 minutes, but if you really make the look works online in the dbms_redefinition package. See the manual of the PL/SQL Package and Types, then look at the note support for Oracle at the following address:

  • GMAIL: I don't want to download ALL messages

    Hello

    I really want Thunderbird to work for me, but I don't know if he can. I have three addresses, a personal gmail and labour two, and I've been using gmail itself in order to coordinate the three. It does not work for me so I would use Thunderbird. The problem is, whenever I try to add my gmail account to my Thunderbird it downloads all of his messages. I thought that IMAP is designed so that e-mail messages are NOT downloaded? My gmail account takes more than 50 GB of space, and I can't allow me to download it. So is it possible to have Thunderbird acts as INTERFACE to my gmail account without HAVING to download a message?

    Thank you..!
    Best,
    Nick

    You can configure Thunderbird not to save local copies, but it may then become unbearably slow when you browse through your messages.

    Tools | Accounts settings | {Select your gmail account} | Synchronization and storage

    Uncheck "keep messages for this account on this computer. Also look at advanced, on the same page of settings and make sure that all files are unchecked.

    She can speed up things a bit if you right-click on the account, select new query and select only the records you want to see.

    For most people with your query, I would say that 'use webmail' (i.e. the google Web site), but I must say that I find it unpleasant to use. I assume you are also less satisfied with it?

  • By clicking on an elements of the taskbar (or on the Start Menu) ask me each time if I really want to open this file. How to stop this?

    When I click on the item to taskbar Windows 7 to Firefox (or on the Start Menu, too), he asks me each time if I really want to open this file:

    ... \ick Launch\User Pinned\TaskBar\Mozilla Firefox.lnk

    I say YES and it opens... until next time, when he asks again.

    But a double click on the shortcut of Firefox on my desktop doesn't only!

    I tried unpin and re-pinnning program without success.

    I tried to create the pinning of the original exe or shortcut on the desktop or the StartMenu option.

    All have them!  And it has worked perfectly well for years, but I had to reinstall FF today and now it goes.

    How can I stop this annoying feature?

    I found a column that actually addressed this and he said to go to the CMD prompt and enter:

    ICACLS '%programdata%\Microsoft\Windows\Start start\program' /Setintegritylevel (OI) (CI) Medium

    Tried without success.

    Another site told me to uncheck the box that says "ask before opening" but there is no such box on the pop-up.

    Maybe because it's a .lnk instead of a .exe?  I do not know.

    Please do not suggest that I use IE or Chrome instead.  I use IE much... but there are some things that Firefox is just the right solution for.

    Thank you!

    Hi MiloInSanDiego

    The response of the creation of a new user account was because after the steps mentioned by Babu, you said in the post on Jan 3 that you get this message 'Do you want to allow the following program to make changes on this computer' like this could be due to the virus.

    By creating a new user account, if there is a corruption of the profile by a virus, it will be there in the new profile. This is the reason for the creation of a new user profile.

    If you are facing problems with Firefox, I suggest you to post the question in this forum for better support.
