What type of file I use to read a large file of data?

I want to store data in a file and access it later. The data file could reach between 500 and 1000 MB in a binary format.

I might have some memory problems.

I didn't need all of the data in memory, only a few data every time that, for my calculations.

If I use a binary file, I can't read only a few data. I have to load the entire file and then read the data I need.

Is this correct?

If I use another type of file, can I read that a few bytes without loading the entire file?

Maybe a TDMS file?

I would probably use a TDMS file for this because it could also be read in excel if there was enough - just little more flexibility. But you can also do this by using binary types. You don't have to read the entire file when you use binary files. See below.

    Companies can almost certainly view or the other guy, but a pdf file
    should be better for documents. A jpg file is almost never used
    for anything except the photos.

  • I create a logo for a company, but I'm new to illustrator and don't know what type of file to give them for their personal use if themselves don't have Illustrator to work with

    So I designed a logo for a company, they want to buy too! I don't know what type of file to send to them for their personal use. I am new to illustrator, so I'm not sure whether it should be a .png, .pdf or .svg. They don't have access to Illustrator, so they would not be able to view the native .ai file, how can I send the file?

    Whenever I have provide a customer with a logo, my first question that would be what they are they who need for?

    And when you have the response from them, it will give you a good idea of what to provide.

    Second to that I will always create a logo set to compile something like the following:

    1. Original .ai logo - RGB/CMYK/Black/White versions
    2. A set of PNG with transparent backgrounds of different sizes (something like 100px, 250px, 500px, 1000px wide)
    3. A set of .jpg in various sizes (something like 100px, 250px, 500px, 1000px wide)
    4. And now a .svg and .pdf file

    Once again it all depends on what the customer wants it, but once you have furnished with everything that they are able to use it for the most part.

    Good luck

  • How can I tell Lightroom what types of files (extensions) I want to be able to import?

    I had copied a. PNG file in the source folder and I wanted to import in the Lightroom Catalog.

    However the import dialog box does not show this file in the source folder at all.

    I also tried the method to select the source folder and using the option "synchronize". But who has not shown the. Either the PNG file.

    My clumsy work around was to open the file in CS6 and save it as a. JPG file.

    So my question: How can I tell Lightroom what types of files (extensions) I want to be able to import?

    You can't tell Lightroom what file types to import in the import dialog box. You could, if you wanted to, check that the boxes of file types to be imported, but it is a "manual" operation, it cannot be automated.

    In regards to the PNG files, Lightroom will NOT import them. The PNG files are not supported by Lightroom. In fact, Lightroom will import TIF, JPG, PSD, DNG and some RAW and film formats. Any other type of file cannot be imported into LR.

  • What Type of file?

    I beat the monster format. The monster format as Adobe first Elements 10 will not support two videos at once or DSLR bother at all. I conquered it by downloading a software that allows me to convert videos in a particular file. So, I need to know what type of file is better supported and convenienty used in EPA 10. Can someone tell me?

    The best thing to do would be to convert the Canon AVCHD video. Then you can load the two AVCHD videos in a project. But this will only work if you have shot your film to Sony in FH or mode 1920 x 1080 HQ and you turned your Canon video at 1920 x 1080.

    (1) open a new Premiere Elements project. Make sure it is set up for DSLR 1920x1080p30.

    (2) connect your Canon camera to your computer via USB and use Media Get / Flip camcorder, AVCHD or hard drive to open the video importer and import the files from the camera to your video project.

    (3) put the video on your timeline and use share/computer/AVCHD with the preset for M2T 30 fps 1920 x 1080 to your movie as an M2T file.

    (4) open a new project set up for AVCHD Full 1920 x 1080 with 5.1 audio (since your Sony pulls in 5.1).

    (5) use Get Media to bring your film from Sony and created M2T files above and start editing.

    Or download the version 11. In which you can just load everything at once and just change!

  • How do I know what type of hardcore is used?

    Hi all
    I'm a newbie dba. I was doing a bit of study on the optimizers. Can someone help me to find out what type of optimizer based on CSSTidy is currently used in my database. Is there both table where I can ask questions and whether it is a RBO or a CBO.
    I have another doubt. some body help me please with the difference between the use of "in" and "exist" in a select query.
    Thank you!

    OPTIMIZER_MODE is a level parameter Instance (in initSID.ora or spfileSID.ora file) that you can view with an OPTIMIZER PARAMETER SHOW
    (or by querying V$ PARAMETER).

    Individual sessions can also define specific settings that influence the optimizer with ALTER SESSION command while the SQL statements can include advice (from a large number of tips available) that influence the optimizer.

    IN and EXISTS are semi-join operations. If you use one or the other used depends on which table would be the best driver. However, apparently since the 9i, the optimizer is smart enough to transform queries.

  • What is the function is used to read the form of angular Position a task?

    I created a task DAQmx in MAX. This task configures a counter on a PCI-6259 to counties of A and B of a coder with the angular Position. Which function to use to read the value since I am more counties of reading I read the position?

    Thank you in advance for any advice!

    Hi Izzy,

    I created the task UP. The task takes in the counter of an encoder input and converts it to angular position. Always use the DAQmxReadCounterF64 function to read the meter? I'm guessing that I made and that the function returns the angular position, rather than the raw numbers. Not sure if.

    Thank you for taking the time to answer.
