• the export dump file size

  Hello

  in 10g is R2 possible to estimate the export dump, a schema in the file size?

  I found this in the documentation

  Syntax and Description

  ESTIMATE={BLOCKS | STATISTICS} 

  But how to use it for an entire schema without generating dump file?

  Thank you.

• Why the JPG file size decreases when Lightroom writes meta data?

  Lightroom uses the files sidecar XMP for meta data history for RAW files. When writing the metadata (e.g. tags) to JPG files, they are written directly in the header of the file. This should leave the image information in the file intact. However, the file size decreases (about 0.02 MB) when Lightroom writes metadata for the original JPG file. As far as I could see, the image information remain unchanged and no other information in the header is deleated, but why decreases the size of the file then (I expect to increase slightly or stay the same)? I work with RAW files for most but sometimes I just versions of the files to work with JPG and I don't want to lose any information.

  Thanks in advance for your answers.

• Calculation of Quickie of the export-PDF file size?

  I have a document Indesign CS4 (816 pages, 3.5 GB) I want to export in PDF format in less than 200 MB pieces. Is it possible to request an approximate exported PDF, to save size guess them where do breaks and having to export several times in InDesign?

  Well, your 500 x 250mm @ 300 dpi images are about 60 MB

  What I would do is export the PDF file as a whole, then I use the extract Document pages and select as simple Pages.

  Then you have the PDF pages separately. You can then select and group them in your Finder or Explorer.

  When you select a bunch of files, you should get a reading on what file size they are.

  You can then say to tuft of 180 MB of using Acrobat files to combine into a single pdf file.

• Why archive log file size constantly change?

  I have a question related to the size of the archive log file:
  I constantly receive a different size to the size of the log file archive, of course, they are smaller than to the size of the log file.
  A guru can explain to me: what possible reason could be?
  Thanks in advance!

  It can happen due to several reasons:

  When you perform a manual archive (via ALTER SYSTEM ARCHIVE LOG CURRENT/ALL)
  When Oracle must respect your ARCHIVE_LAG_TARGET (defined in seconds)

  Unless you do a manual check-in, your parameter ARCHIVE_LAG_TARGET is the reason why you see Archives of logs with different sizes as Oracle has archived the redo log as soon as the time ARCHIVE_LAG_TARGET is reached. Even if the redo log is not full, Oracle will always have to archive the redo log.

• Why a jpg file size grows when I OPEN it in Photoshop before you do anything for her?

  I open a jpg file which my trusty Mac tells me is 2.4 MB, but Photoshop has immediately 34.8 Mb in size of the image. It is a picture of 72 dpi which is 59,333 inches width x 39,556 inches in height. I want to REDUCE it to one 17 "(approx.) size 11" for printing, which allows Photoshop to increase the resolution. I UNCHECK resample, and enter a width of 17. I have 17 inches wide; 11,333 inches and a resolution of 251,294 inches. Great! What I don't understand, however, is that - without Photoshop add no matter what pixel (remember, I REDUCE the size of the photo without resampling) - the size of the file is more than 14 times larger. The same thing with each jpg Photoshop I opened: 129Kb photo opens in Photoshop to 482.6 Kb; a 1.2 MB file opens to 5.49 MB, etc. I didn't not do anything at all, but open them. Without a doubt, it's something I should have learned (maybe you) long, long ago, but it has baffled me now. Very grateful for any help.

  The size you see in the finder is the compressed size. When you open it in Photoshop, you can see the enlarged size.

• Why is my file size "Combined PDF" smaller than the original files?

  Hello!

  I try to combine two individual PDF files into a single PDF file. Each file is 32 MB, but when I use acrobat to combine, the newly created "combined" file is only 19 MB. I think I took the necessary steps to ensure no degradation that happens (e.g. large selection size of the file in the Panel options), but I'm still puzzled as to how the two files can be set up as one and be smaller than the two separate files with out any compression. What Miss me?

  Thanks in advance!

  When you combine a file, it performs an operation of "save under".  This rewrites all the PDF object in the single file and is supposed to clean the file, while the single files may have had several saves which when you look at the inner workings of the PDF file simply add at the end of the file.  In other words, you get a file more cleanly written and optimized is also recorded for a quick display of Web pages.

• Why can't I reduce the file size of virtual disk?

  Workstation help 8.0.4, why is the file size of virtual disk for my more bigger than the amount of space used within the instance instance?

  The instance (Windows 7 Ultimate 32 bit) HARD drive is 40 GB... He is currently using 28.6 GB of this space.

  But the hard for instance file is 34.5 GB size - it is more than 20% larger.

  I defragmented the drive on the instance.

  I defragmented and compacted file hard (via the 'vmware-vdiskmanager' command line utility)

  I defragmented the host drive.

  Any not really - I'm just curious as to why I can't get it down to a smaller size (mainly to speed up backups)

  Narrowing of a virtual disk is done in two steps. Unused disk space must first be cancelled in the comments, what OS, then blocks not null the hard are copied to a new file hard. With VMware Workstation 8, you can start this process in the VMware Tools window (right-click the icon in the system tray)

• Why are my files so huge and so amazing necessary RAM (Adobe After Effects

  I don't want to do too much in the project, I literally just put audiowaves on a photo and a .wav in the background.

  I put them all together in a publication, but he stutters a lot (I'm literally under a GTX Titan Z and he need 30 + GB of RAM) so I can't hit even 30 FPS and when I export, the file sizes are 25 gigabytes.

  What I'm doing wrong, this causes this massive spike no reason apparent, because I'm not even rendering moving images

• Photoshop can change the size of the canvas for very accurate measurements

  I need the exact measurements for the size of the canvas that needs to be 704,55 mm wide. I noticed that when I create a new document and insert this size for the width of the document it takes 704,51 mm if I check the size of the canvas under Image > canvas size. No explanation as to why it changes the size of the canvas to very exact dimensions?

  Thank you

  An image cannot be fractions of a pixel. Imagine that you have an image that has a resolution of 3 ppi. It's less than an inch to 3 pixel image. Now, you mean a size of 0.5 inch canvas. This would mean an image composed of 1.5 pixels, which is impossible. The image must be rounded to the nearest one who welcomes a whole pixel. You can either simply decide that it is good enough (it is usually), or use a resolution so that the size of your canvas has more pixels that can be divided into your desired size, then maybe you can be able to adjust your resolution exactly to the size of your canvas.

• Why the file size does not change when I use "Process multiple Images" to add a watermark?

  Hello

  I use 11 elements. To add a watermark to a lot of JPG photos at the same time, I use the function 'process multiple files.

  I select a source folder and a destination folder and adds a number to three numbers for each file. I do NOT check the box marked 'change photo size. After that, I set the watermark I want printed on my photos and hit OK. All files in the source folder are processed and saved with a new name in the destination folder. Loyally.

  But. The file size of the new file is strongly reduced, compared to the original. He's going from 10 MB to 500 KB (in general). Why is this? Is there a way I can help?

  Kind regards

• Why the change in file size is not a difference in how I can put on a cd?

  I'm trying to burn audio files to a disc that will play in a cd player.  The size of the files is not that big.  If I just dropped everything on the disk in the form of data files, they would be easily fits on the drive with plenty of room to spare.  BUT when I go through Windows Media Player or I-Tunes to make the drive, it takes 5 discs to fit everything on.  I changed the WMA files into MP3 files, but it remains the same.  Then, I used Windows Media Player to convert the files to a file size reduced.  But it seems not to matter.  There are still 5 discs.

  There is obviously something that I don't understand the difference in burning data instead of audio files and the size of the file.  I'd appreciate any help I could get.  Thank you!

  If you notice on your empty CD there are two limitations...
  for example I have one here that says... 80 MIN / 700 MB...
  (this means time 'or' file size... not both)

  If you create a... Audio / music CD... (one that will play in)
  most CD players)... the limits are dictated by the duration.
  If you see the directory on an Audio CD / music you will be
  Notice the files have extensions of the ADC (this is the result
  regardless of the format of the source files).

  If you create a data CD... for example a MP3 cd which will be
  play in a player compatible with MP3 files... the limits
  are dictated by the size of the file.

  Then you have a player that is MP3... you could
  create a data CD with a lot of files unlike Audio

• The Lightroom export file size: why it's so small? How can I maximize the picture quality?

  My image file size is much smaller after editing and export through Lightroom. It is impossible to maintain the size of the original file in order to preserve image quality? This small file size will have a negative impact on the prints? Any help is appreciated!

  The file size is not an indicator of picture quality! You are looking at the wrong measure.

  File size is determined by the number of pixels you have, the quality slider in the dialog box export and of a dozen other things, most of which you cannot control.

  Want to watch the number of pixels (width and height) and not the size of the file.

  It is impossible to maintain the size of the original file in order to preserve image quality?

  Not only is impossible, that it is also meaningless (see above)

  This small file size will have a negative impact on the prints?

  Instead look at the size of the file, you must look at the number of pixels of the exported photo (width and height), and this will determine if you get a decent impression. The usual standard is that you need 300 pixels per inch.

• Why the same photo's file size different in Photos and in the Finder?

  I have a photo size 4608 x 3456. When I open the file information in the Apple's Photos app, it says that the file is 7.8 MB. When I open the same photo in the Finder and look at the news file, it is said that it is 3.1 MB on the disk. Why does this happen? All other metadata is the same in the pictures, Finder, Lightroom or Photoshop, but I can't understand why the file size seems to have changed since I dragged photo pictures to the Finder.

  Thank you.

  How you view the photo in the finder (you shouldn't be messing around inside the photo library)?

  If you export or drag / drop you create a new file with a different compression - using export allows you to control what
