filesize

问题 I have been struggeling on how to get the valid filesize of a file that is >= 2 GB in PHP. Example Here I am checking the filesize of a file that is 3,827,394,560 bytes large with the filesize() function: echo "The file is " . filesize('C:\MyFile.rar') . " bytes."; Result This is what it returns: The file is -467572736 bytes. Background PHP uses signed integers, which means that the maximum number it can represent is 2,147,483,647 (+/- 2 GB). This is where it is limited. 回答1: http://us.php

问题 I'm creating sparse files in python as follows: >>> f = open('testfile', 'ab') >>> f.truncate(1024000) >>> f.close() when the file is done, it takes up 0 disk space, but its inode size is set to my truncated value (1000K): igor47@piglet:~/test$ ls -lh testfile -rw-r--r-- 1 igor47 igor47 1000K 2010-07-09 04:02 testfile igor47@piglet:~/test$ du -hs testfile 0 testfile How do I get the file's real space usage (allocated size) inside python? The stat call returns the file's apparent size, and I

问题 I am currently working on a system that involves storing multiple studies and details of their contents (A study can typically contain 1 < X < ~2000 images). My colleagues and I were discussing what might be the best method of storing files sizes (specifically the image sizes) in a database would be. The file sizes typically range from < 1kB to > 20MB. We are currently debating between storing the images sizes as: # of kilobytes (as an integer value) # of bytes (as a large integer value) # of

问题 I have a list of (.TIFF) files which I am renaming and saving in the same format. I am using cv2 module to do this. import cv2 import os import glob os.chdir('C:/99_Temp/') for file in glob.glob("*.tiff"): f = os.path.splitext(file) time_val = f[0][:2] a1 = cv2.imread(file) cv2.imwrite(time_val+'.tiff',a1) Why are the file sizes reduced from the original TIFF file? I haven't done any processing and visually the images look the same. But I am wondering, why the difference? 回答1: There could be

问题 I'm trying to download an image from url and I need to display the size of the file and the progress of the file downloading. This is what I have. int bytes_downloaded = cursor.getInt(cursor .getColumnIndex(DownloadManager.COLUMN_BYTES_DOWNLOADED_SO_FAR)); int bytes_total = cursor.getInt(cursor.getColumnIndex(DownloadManager.COLUMN_TOTAL_SIZE_BYTES)); final int dl_progress = (int) ((bytes_downloaded * 100l) / bytes_total); runOnUiThread(new Runnable() { @Override public void run() {

问题 I am working on a Windows MFC application. I am preparing a report list in my design using CListCtrl were I can list the name, size, type and modified date of the file. I do not know how to display the size of a file. Do any one know how to do that? 回答1: To get all your info in one shot, use: CFileStatus filestatus; CFile::GetStatus( filename, filestatus ); 来源： https://stackoverflow.com/questions/1801914/finding-file-size-windows-mfc-application

问题 I know one difference between ogg video and mp4 video is that ogg video doesn't have metadata describing the file size, so when an ogg video is loaded, the controls can't show the time remaining until the file has fully loaded. This can be a problem if the ogg video is more than a few minutes long. Is there a way to get this filesize when the page is requested?

问题 This is a simple one (I think). Is there a system built in function, or a function that someone has created that can be called from Delphi, that will display a number of bytes (e.g. a filesize), the way Windows displays in a file's Properties box? e.g. This is how Windows property box displays various sizes: 539 bytes (539 bytes) 35.1 KB (35,974 bytes) 317 MB (332,531,365 bytes) 2.07 GB (2,224,617,077 bytes) The display is smart about using bytes, KB, MB or GB, and shows only 3 significant
