Cp and mv just increase file size without quitting on btrfs

hi all,
sry for the uncertain topic description but i didn't know how to describe this bug properly.
every time i copy or move (using coreutils) a file from one btrfs partition to another, cp and mv just create the file in the destination folder but won't quit after the file has been transferred.
this means the file grows and grows until the size of the volume has been reachead (I/O error no more free space available).
is it a known bug? caused by btrfs or coreutils? rsync works fine!
best regards

thanks allan, downgrading coreutils helped.
strange, i guess i didn't notice it until now since i rsynced without problem to external drive this whole time, which ext4. but cp/mv messes up (as per this topic title). so it's not just between btrfs..
in fact, i have two btrfs harddrives on my laptop with multiple subvolumes on each one. most are compressed. i can cp/mv between compressed and non-compressed, regardless of which btrfs device, without having this error at all. the only time i have a problem is cp/mv to NON-btrfs filesystem (so far tested with ext4 and reiserfs, both mess up with cp/mv but not rsync). but yes, downgrading coreutils helped. just thought i'd share my experience with it. hopefully 2.6.38 will fix permanetly but i'll have to wait on that.

  • How to decrease PDF file size without losing quality of images and vector lines?

    I have several ai files that I saved as PDFs. Now I'm having problem with the size of this combine files. Can some one assist me with the proper way on decreasing file size without losing quality.
    Thank you.

    I am having the same problem with a different file that's in a different format mentioned above. I'm trying to convert a ".srf" file and turn it into a ".pdf." I was successful doing this but my image, once in a .pdf was also pixilated.
    I thought if I convert my ".srf" file to a ".jpeg" first, then bring this newly created ".jpeg" into a ".pdf," I would have more luck. But unfortunately the free download I got on my computer that's supposed to convert any file to any file, CANNOT convert ".srf" files to ANYTHING!
    Does anyone have any ideas? Or any specific programs I should get?
    Thanks!

  • Help!..CS4 IS INCREASING FILE SIZES.

    Hi all
    Wondered if anyone has had a problem with increased files sizes when opening a document up in Photoshop? Anything i open up is increased by two thirds  in file size and i've no idea why ( e.g..8MB doc opens as 24MB doc)
    What is even more strange is that it won't let me reduce a  file size to anything under 1MB.
    Has anyone ever come across this problem?...would appreciate any help.
    Thanks

    Hey Noel
    Fair Play.
    This is what is happening.
    I’ve got a standard JPEG file that viewed in Explorer and Bridge reads as a 2.70MB (2838,796 bytes) file. Pixel dimensions 797x1000. Document size  6.75 x 8.47cm .Res 300 PPI.
    When I open it in CS4 it reads 2.28MB. (This is the first thing I don’t understand)
    Either way my simple( so I thought ) objective is to decrease the file size.
    In the image size box I have re-set the resolution to 72ppi as I just need to post the image on a Website. My before and after calculations in the image Panel reads (was 2.28MB...now 134.3k)
    Great! .this is what I want, However..... when I ‘save as’ and the JPEG compression box appears it has suddenly increased the file to 1.8MB Large file...and only allows me to reduce it to 1.7MB small file.
    Admittedly this is not my area of expertise....I’m doing something wrong so any pointers would be much appreciated.

  • When I import my Sony video, which is in m2ts format, the file size is a few times larger.  This affects the volume of clips for creating the blu-ray or DVD discs.  How can I squeeze the file size without sacrificing the quality of output?

    When I import my Sony video, which is in m2ts format, the file size is a few times larger.  This affects the volume of clips for creating the blu-ray or DVD discs.  How can I squeeze the file size without sacrificing the quality of output?  Is there any other ways of achieving this?

    The command is gone because iDVD has been discontinued by Apple. After Apple discontinued iDVD they removed the iDVD burning link from iMovie. I still use iDVD sometimes, only because I have an old copy.

    Photoshop is not amateur-level software, and although it can edit a video, it cannot burn a DVD. Unfortunately, because I still use iMovie, I haven't tried anything else. You might want to read the reviews of various DVD-burning applications in the Mac App Store.

  • Why the files my program create are created twice each file double ? And why sometimes the files size are too small ?

    My program is using Queue of type Uri to create Queue of urls and then i'm using webbrowser to navigate each Uri from the Queue in it's turn and get the url(html) source content and save it to the hard disk.
    The problem is sometimes the text files on the hard disk are small like 90KB or 60KB and sometimes they are as they are suppose to be 300KB or 200KB.
    This is a button click event where i'm calling two methods:
    private void toolStripButton3_Click(object sender, EventArgs e)
    GetHtmls();
    CheckQueue();
    This is the GetHtmls method code:
    private Queue<Uri> myUrls = new Queue<Uri>();
    private bool isBusy = false;
    private void GetHtmls()
    for (int i = 1; i < 49; i++)
    adrBarTextBox.Text = sourceUrl + i;
    targetHtmls = (combinedHtmlsDir + "\\Html" + i + ".txt");
    Uri targetUri = new Uri(sourceUrl + i);
    myUrls.Enqueue(targetUri);
    sourceUrl contain website address: http://www.tapuz.co.il/forums2008/forumpage.aspx?forumid=393&pagenumber=
    And i'm adding to it the numbers and create the pages.
    And add them to the Queue.
    THen the CheckQueue method:
    Uri uri;
    private void CheckQueue()
    if (isBusy)
    return; // We're downloading some page right now, don't disturb
    isBusy = true; // OK, let's get started
    if (myUrls.Count == 0) // No more pages to download, we're done
    isBusy = false;
    return;
    uri = myUrls.Dequeue(); // Get one URL from queue
    getCurrentBrowser().Navigate(uri);
    It suppose to Navigate to each Uri(html address) in the Queue.
    And the browser document completed event:
    private void Form1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
    // If page loaded completly then do something
    int urlnumber = uri.ToString().IndexOf("pagenumber=");
    string number = uri.ToString().Substring(urlnumber + 11);
    int num = Int32.Parse(number);
    targetHtmls = (combinedHtmlsDir + "\\Html" + num + ".txt");
    StreamWriter writer = File.CreateText(targetHtmls);
    writer.Write(getCurrentBrowser().DocumentText);
    writer.Close();
    isBusy = false; // We're done
    CheckQueue(); // Check next page in queue
    In the completed event i'm getting the page number and build the string for the text file then write the html source content to the text file.
    In the end i have on my hard disk 48 text files.
    The problems are:
    1. Sometimes it seems like it's not finishing navigating to the current uri or maybe some other reason maybe server side problem and creating small size files with source content inside but not all the source content. Sometimes the text files size are each
    file 99KB or 70KB and sometimes the size of them are about 300KB and 200KB and this is the right sizes 300KB 200KB.
    2. The text files on my hard disk suppose to be 48 different files each file should contain the source if the html page of the 48 pages. But on my hard disk the 48 text files are duplicated for some reason.
    This is the file on my hard disk:
    Some of the files are 205KB 350KB 175KB and some of the files sizes are 85KB 94KB 35KB 
    Why some of the files it didn't navigated to the end or maybe didn't got all the source ?
    And why it's making each second file the same like the one before ? It suppose to create 48 different files but i'm getting two identical files each navigation.

    I solved it now.
    This is what i did:
    It's a bit slow process since i'm waiting for each page to be loaded into the webbrowser but it does the work.

  • Increase File Size

    After converting CR2 Raw files to Jpeg the size of the files is too small. How if possible Can one increase file size in Elements 9? Thanks  

    Why on earth do you want to have "larger" files?
    JPG uses compression to reduce the size of the resulting files.  If you're concerned about the picture quality because of JPG's lossy compression method, simply set the JPG "Quality" setting to its maximum.

  • How do you add full folders and not just individual files in the new itunes?

    How do you add full folders and not just individual files in new itunes? i just reformatted my HD and went to add all my music and it's only letting me add files not folders!?!?

    "Add Folder to Library" is still in the file menu, but you might need to bring up the menu bar to see the file menu.
    If you're using 11.0.x, click on the wee boxy icon up in the top-left corner of your iTunes to see the "Show Menu Bar" control, as per the following screenshot:

  • BUG: "Save and compact" increases file size by 1KB each time?

    Flash CS4
    I noticed that when I do "save and compact" on a .fla file, it causes the file size to increase by 1KB each time--even when no changes were made.  Can this be fixed?

    Yup. It works perfectly in CS3. Now the problem you will have is that you don't have CS3 installed. Even if you will save your files as CS3 format, you cannot (as far as i know) "save and compact" it as CS3, it will prompt that it must be converted from older version CS3 to CS4 and you end up with the same problem. Perhaps there is a setting to force CS4 to save and compact in CS3 version but i doubt it. The only way i know to solve it is save the file as CS3 format (But you will lose some XMP file info metadata, i'm not sure if that is necessary though) then close CS4, and open CS3 then "save and compact" it there. This is definitely a bug where some information might have been duplicated in the file's info or history. If you are lucky an adobe employee might be able to give you a solution to this or just confirm this bug.

  • Reduce File Size and Optimise PDF both increase file size

    Hi All
    I have exported a pdf (our college mag) at smallest file size from Indesign CS4 for online use. The problem is the resultant file size is a little under 19Mb. Using both or either Reduce File Size or Optimise functions simply result in an increase to 22Mb. The document is packed with images however I would have thought one or both of these processes would have helped reduce the file size to a more manageable download file size.
    A pdf is also produced to go to print so simply compressing all images prior to imcuding them in Indesign is not a preferable option - this would mean creating two separate Indesign documents, something which I would rather avoid if possible.
    Any help would be greatly appreciated as always.
    The file reside here if anyone cares to take a look http://www.ayrcoll.ac.uk/index.php?name=UpDownload&req=viewdownload&cid=11&orderby=dateD  It's the latest release (September 09)
    Thanks
    Colin

    You might want to do an audit of the PDF (button in PDF Optimizer) and try to figure out what the various parts are. It shows 58% is content streams (sorry, but I am not sure what that is), 26% is overhead, and only 12.7% is graphics. Since you are not storing bookmarks and such, you might want to try going back to ID and printing to the Adobe PDF printer for a comparison. It may be one technique is more efficient than the other.
    When I used the optimizer, the file did get larger. When I used Reduce File Size, it got slightly smaller. The key may be in figuring out what the various parts are from the audit. You might try copying one page of ID to a new document and play with various versions - different fonts (all were embedded and that is probably best), variations on graphics, etc. That is all I can suggest since I would simply be playing with different ways to produce the document and looking at what is causing the bloat. When the Images are only 12.7% and the fonts less than 1%, there is something going on to produce the size, and those 2 are typically the killers. I would mention tags that tend to bloat, but you do not have any (normally used for assessibility).
    You might want to try some of the preflight checks to find issues. I did the transparency check and got 170 instances in 22 pages. Flattening the page may help. There were some pages that seemed to be very bad. However, I did not get a big file size reduction. I did not get a lot of improvement by printing to a new PDF either. Certain pages seem to be part of the bloat problem. The print took a long time around pages 11 and 22.
    One troubleshooting technique would be extract pages to separate files and look at the details of each page to see what is causing the issue.
    Need to go. Good luck.

  • Converting to DNG without RAW embed increases file size...????

    I convert all my Canon CR2 Raw files to DNG. I have recently noticed though that selected folders full of these DNGs are twice the file size of the original CR2. The thing is, I have never embedded the original CR2. My file sizes go from a little over 12M to 25M in the conversion. When testing to try to find the problem, I found that when I do embed the original that file size increases to 30M. If I try to go backwards, selecting a folder that contains the larger-than-normal DNGs, and I try to extract the original CR2, it tells me there is no original to extract. So from everything I can tell, these files are doubling in size for a reason other than the original Raw file being embedded. As far as I can tell, there also is no rhyme or reason to how some folders end up with normal file size DNGs, and others are double the file size....Anyone know?

    Reed:
    Why don't you use the lossless compression algorithm? Absolutely no data is lost. Not a single bit is changed. The image data is preserved EXACTLY. That is what "lossless" means--there is no loss at all. The "way you see it" is wrong.
    The ONLY reason the uncompressed option is available at all is so simple third party utility programs can read the files if their programmers have not written the code to decode the lossess compression agorithm yet. Even this is less of an issue now since Adobe provides the free DNG SDK with source code that does this decoding.

  • CS4 exporting and reduction of the file size

    Hello,
    I'm new to the Premiere pro. I'm trying to export the movie, which as a final product will be uploaded on the Web for the employees to download it on their computers.
    It is a similar situation as TreeHugger98 posted on: http://forums.adobe.com/message/2004696
    I had 3 WMV recordings of a Microsoft Live Meeting event - a conference call, with a bunch of PowerPoint slides and the audio of the presentation/discussion. Each about 25MB and 2 fps, 704 x 528, 16000 Hz - 16 bit, Mono. 
    I have selected the settings for the project: (I'm in US) 720 x 480, 29.97 fps, 32000Hz, stereo, and scaled to the size.
    I combined a few bits and pieces in one, so the final movie is 2 hrs long. I need to have a reasonable size output, so the file has to be downloadable, however no matter what settings I tried - the size is enormous, not to mention the rendering time. It doesn't have to be saved for both platforms - apart from designers, all employee have PC, so do I.
    Could anyone help?
    Thanks in advance

    robodog2,
    Thank you for answering - sometime I feel that all you guys are being bored with getting one question over and over, but I assure you your answers are being highly appreciating by newcomers such I myself.
    I'm new to the Premiere pro. I'm trying to export the movie,  which as a final product will be uploaded on the Web for the employees  to download it on their computers.
    You just need to put a file up on the web, not a "playing " movie ?  So they download the file ? - YES, this is what I meant, (however I tried to publish the mpg4, just to see what I would get).
    I  had 3 WMV recordings of a Microsoft Live Meeting event - a conference  call, with a bunch of PowerPoint slides and the audio of the  presentation/discussion. Each about 25MB and 2 fps, 704 x 528, 16000 Hz -  16 bit, Mono.
    this isnt very specific...like how many bytes did you start out with to begin with for each source ( asset ). wmv is very compressed and it really isnt perfect for "editing" as it is a "delivery" format...for viewing, not editing...
    Regardless, if you export that to anything that isnt really compressed it will probably be a larger "byte count" than you started with, because wmv is very compressed to begin with... know what I mean ???
    2 hours of avi type 2 SD ( standard definition 720x480 ) is roughly 26 GIGABYTES in byte count....
    These are the details of the files I started out with: exactly the size were: 20MB, 25MB and 24MB, all of them 2 fps, 704 x 528, 16000 Hz -  16 bit, Mono.  I have read about the compression, but this is very valuable information: what file type would be perfect for editing then?
    I have selected the settings  for the project: (I'm in US) 720 x 480, 29.97 fps, 32000Hz, stereo, and  scaled to the size.
    without knowing what you had to begin with who knows what this project setting did...but basically you must match your assets specs with the project settings....
    Which are what, in this example...? I went trough all the available settings and I couldn't decided which would be the best. I was only sure, that it had to be NTSC aspect ratio 4:3.
    I combined a few bits  and pieces in one, so the final movie is 2 hrs long. I need to have a  reasonable size output, so the file has to be downloadable, however no  matter what settings I tried - the size is enormous, not to mention the  rendering time. It doesn't have to be saved for both platforms - apart  from designers, all employee have PC, so do I.
    "no matter what settings I tried " doesnt tell me anything really...I have no idea what you tried ....please be more specific about this....and what the parameters of your final product have to be...in other words, can you downsize the product a little bit ? Make it smaller than 720x480 ?
    What do the people who get this have to do with it ?? Just look at it ?  So maybe it doesn't have to be 720x480....making it smaller on the export side would make the byte count smaller and still be OK to view on a computer.
    I have tried .mov,. mpg4 and back to .wmv again. I can go smaller than 780x480, unfortunately because of the compression the video is not very good quality to start with. The solution would be to use original presentation, save each slide separately an import to the project. Do you recommend doing that?
    Thank you,

  • Acrobat 9 Typewriter increasing file size

    I have scanned forms that I need to edit with the Typewriter tool in Acrobat 9 Pro - basically I just need to add a date to the form and then e-mail it.  Evidently I have accidentally clicked some box that I did not want to click, because now when I edit the one-page form (about 70k before editing) and type in any data whatsoever using the Typewriter tool, then save the form, the file balloons to anywhere from 0.6 to 0.9 MB.  Which is crazy, and too large for me to submit.
    Right now what I'm having to do is edit the form, save it, print it, and re-scan it.  This is making me nuts.  Does anyone have any suggestions?
    I have tried Reduce File Size, the Optimizer, and downsampling, but nothing has worked.  I can't make the file small enough to make a difference.
    Thanks,

    Base - 14 fonts
    Standard Type 1 Fonts (Standard 14 Fonts)
    Fourteen typefaces—known as the standard 14 fonts—have a special significance in PDF documents:
    Times (v3) (in regular, italic, bold, and bold italic)
    Courier (in regular, oblique, bold and bold oblique)
    Helvetica (v3) (in regular, oblique, bold and bold oblique)
    Symbol
    Zapf Dingbats
    These fonts are sometimes called the base fourteen fonts.[34] These fonts, or suitable substitute fonts with the same metrics, must always be available in all PDF readers and so need not be embedded in a PDF.[35] PDF viewers must know about the metrics of these fonts. Other fonts may be substituted if they are not embedded in a PDF.
    Helvetica was developed in 1957 by Linotype. Arial was Monotype's attempt to make a font that looked like Helvetica (but without paying licensing fees) and was designed in 1982.
    Microsoft didn't want to pay Linotype licensing fees to use Helvetica so it went instead with the cheaper Arial.
    Arial is held in disregard by many professional typographers and type enthusiasts, for reasons relating to its similarity to other typefaces and the involvement of Microsoft in its development and distribution.[7] It is reinforced by Arial's apparent status as a de facto Helvetica stand-in, but without paying royalties, or credit, to Helvetica. Arial's glyph widths are nearly identical to those of Helvetica,[7][26] rather than Monotype Grotesque, on which Arial is otherwise based.[7] "But to an experienced designer," writes typographer Mark Simonson, using Arial "was like asking for Jimmy Stewart and getting Rich Little."

  • Reducing file size without loosing clarity

    I have two designs for labels that have to be approved by the government for type size regulations.  The current size of the illustrator files are 133.3 MB and 24.7 MB I need to provide these at no larger than 450 kb AND the type must be readable and measurable for approval.
    I have tried everything I can think of to provide the artwork small enough yet still retaining enough resolution to not make the type fuzzy and not able to be measured for size.  I've tried making the files from within illustrator, I've tried taking everything into Photoshop to make the JPEGS with no luck.  They want either a gif, jpeg or tiff no larger than 450 kb that is viewable at the print size of the label with no loss of resolution... Does anyone have any suggestions on how to create these?
    Thanks in advance,
    Nina

    Photos, type gradients, complex paths, etc... and yes I know if they would just accept PDF files it would be no problem, but this is the Federal Government.  Do they ever do anything the easiest way.
    I think I figured out a way to get these down in size without lossing too much... I took the background with all the complex paths and I made a separate JPEG put that back into an illustrator file, placed the type over it and made an RGB JPEG out of illustrator...used the type hinting and a low setting.  Got it down to 425 kb and well the type looks pretty darn good.  I hope this works because I've done this well over a dozen times and they've all been rejected.  This is the info the agency sent regarding it being rejected:
    "Per Industry Circular 2011-4, your application and label(s) have not been reviewed for type size, characters per inch or contrasting background. The responsible industry member must continue to ensure that the mandatory information on the actual labels is displayed in the correct type size, number of characters per inch, and on a contrasting background in accordance with the TTB labeling regulations, 27 CFR parts 4, 5, 7, and 16, as applicable."
    "One or more of your label images appear too small for the proper evaluation of your label(s). When the dimensions you specify are applied to the label, the system renders your label as a blurred image. Please remove the current image(s) and replace it with new, larger image(s). We advise that, when you develop your label images, the compression ratio should be set at MEDIUM or LOW so that the file is still within the file size limit of 450KB"

    What exactly is happening, and how can I fix it?
    Thanks for any info.

    Hey, Jon
    Interesting...
    Original file (300 dpi CMYK images) 23.8 MB
    Images 19 MB
    Color Spaces 0.8 MB
    Optimize with flattening (72 dpi images, low quality) 68.7 MB
    Images 49 MB
    Color Spaces 18 MB
    Optimize without flattening (72 dpi images, low quality) 68.2 MB
    Images 48 MB
    Color Spaces 18 MB
    Not sure why color spaces are down to 18 MB from 22 MB, I used a preset that I THOUGHT was the same one I used yesterday. Regardless, it's bizarre that both images and color spaces are getting huge when optimized.
    I used Create PDF from Multiple Files to bring in a bunch of pages, but I'm reasonably sure that all those files were already flattened before I brought them in.
    I'll file that transparency tip for next time though, you never know when it might come up.
    Thanks.
