filesize

问题 We are keeping images in Folder which can have images & sub folder & these sub folders can also have images & sub folders for example c:\myImageFolder\image1.png //'myImageFolder' have image c:\myImageFolder\Folder1\imagex.png // 'myImageFolder' have another folder inside which is 'Folder1'. c:\myImageFolder\Folder1\ChildFolder1\imagen.png // 'myImageFolder' have 'Folder1' which have 'ChildFolder1' which have imagen.png We need to know that how many images are in there over 1 MB, over 750KB

问题 I have this home work where I have to transfer a very big file from one source to multiple machines using bittorrent kinda of algorithm. Initially I am cutting the files in to chunks and I transfer chunks to all the targets. Targets have the intelligence to share the chunks they have with other targets. It works fine. I wanted to transfer a 4GB file so I tarred four 1GB files. It didn't error out when I created the 4GB tar file but at the other end while assembling all the chunks back to the

问题 I've been using this method to resize uploaded .JPG images to a max width, but it's resulting in images being larger in kb than the source. What am I doing wrong? Is there something else I need to do when saving the new image? I've tried all sorts of combinations of PixelFormat , e.g. PixelFormat.Format16bppRgb555 E.g: source image is a .JPG 1900w, trying to resize to 1200w... - Source file is 563KB, - resized file is 926KB or larger, even 1.9MB public static void ResizeToMaxWidth(string

问题 I have a PNG image of 168.2KB and 1991x1756 and tried to import it into a Bitmap using BitmapFactory.decodeStream() . The problem is that I run into OutOfMemoryError where the Bitmap size ends up being 13,657KB. What I don't understand is why is the file so big after the import and how to mitigate this. Seems that this OutOfMemoryError issue is very common with decoded Bitmap images but can't find a way to fix it. Any ideas? Bitmap bitmap = BitmapFactory.decodeStream(inputStream, null,

问题 how can i get the "filesize" from a string in php? I put the string in a mysql database as a blob and i need to store the size of the blob. My solution was to create a temp file and put the string into the temp file. now i can get the filesize from the "string". but that solution is not good... greetings 回答1: It depends. If you have mbstring function overloading enabled, the only call that will work will be mb_strlen($string, '8bit'); . If it's not enabled, strlen($string) will work fine as

问题 Is there a good gem for getting recursively calculated directory sizes? In unix, I can use du , but I want a library that absorbs the difference among OS. 回答1: Looks like sys-filesystem handles this, but you'll need to do some math to convert the available blocks into bytes (by multiplying by block-size). 回答2: This seems to work: Dir.glob(File.join(dir, '**', '*')) .map{ |f| File.size(f) } .inject(:+) 回答3: Could something like this work for you? def directory_size(path) path << '/' unless

问题 I need to determin the byte size of a file. The coding language is C++ and the code should work with Linux, windows and any other operating system. This implies using standard C or C++ functions/classes. This trivial need has apparently no trivial solution. 回答1: Using std's stream you can use: std::ifstream ifile(....); ifile.seekg(0, std::ios_base::end);//seek to end //now get current position as length of file ifile.tellg(); If you deal with write only file (std::ofstream), then methods are

问题 Im using a script to get all files and dirs in a specific and generates a .txt file of the result but i need to add the size of each file using the FileGetSize + ByteSuffix functions #include <File.au3> #include <WinAPIFiles.au3> Global Enum Step *2 $GETFILES_NOT_DIRECTORY, $GETFILES_NOT_EXISTS ; GetFiles @error Func G3tAllF1lesAndDirs($cpath, $txtname) Local $sFileList = '' GetFiles($sFileList, $cpath) ; This uses no global variable $sFileList = StringReplace($sFileList, '|', @CRLF) ;

问题 I have a .dmg on my website for a Mac Software, but when i try to download this (even in different browsers), it doesn't show me the duration or the filesize. Could this be something i need to configure in Apache?
