How to get file physical location on hard drive

由 笑着哭i 提交于 2019-12-07 12:12:30
问题 I want to make a file shedder to completely delete a file, by writing zeros to its physical areas. Files may be stored on hard drive in pieces, not always in a whole block. When I say physical areas. I mean the physical sections that the file is stored, or any reference to those sections that I can perform "writing zeros". Better in C#. 回答1: Unfortunately, that is not entirely possible in C# and neither in C/C++ for that matter even if you are writing a kernel mode driver. Quote from the

The most efficient way to delete millions of files based on modified date, in windows

由 纵然是瞬间 提交于 2019-12-07 11:17:18
问题 Goal: Use a script to run through 5 million - 10 million XML files and evaluate their date, if older than 90 days delete the file. The script would be run daily. Problem: Using powershell Get-ChildItem -recurse, causes the script to lock up and fail to delete any files, I assume this is because of the way Get-ChildItem needs to build the whole array before taking any action on any file. Solution ?: After lots of research I found that [System.IO.Directory]::EnumerateFiles will be able to take

System.IO.File.Delete() / System.IO.File.Move() sometimes does not work

由 蹲街弑〆低调 提交于 2019-12-07 07:44:27
问题 A Winforms program needs to save some run time information to an XML file. The file can sometimes be a couple of hundred kilobytes in size. During beta testing we found some users would not hesitate to terminate processes seemingly at random and occasionally causing the file to be half written and therefore corrupted. As such, we changed the algorithm to save to a temp file and then to delete the real file and do a move. Our code currently looks like this.. private void Save() { XmlTextWriter

PHP delete the contents of a directory

由 六月ゝ 毕业季﹏ 提交于 2019-12-06 22:39:58
问题 How do I do that? Is there any method provided by kohana 3? 回答1: To delete a directory and all this content, you'll have to write some recursive deletion function -- or use one that already exists. You can find some examples in the user's notes on the documentation page of rmdir ; for instance, here's the one proposed by bcairns in august 2009 (quoting) : <?php // ensure $dir ends with a slash function delTree($dir) { $files = glob( $dir . '*', GLOB_MARK ); foreach( $files as $file ){ if(

What does it mean if some files in TortoiseSVN are marked “deleted” and others “deleted (+)” with a plus sign?

由 陌路散爱 提交于 2019-12-06 16:44:45
问题 I'm about to do a commit in TortoiseSVN involving rearranging a lot of files and directories. On the "commit" window, there are several files whose text status is "deleted" or "added" but others whose text status is "deleted (+)" or "added (+)". What does the (+) mean? (It's quite difficult to Google for a plus sign, and the word "plus" turns up lots of hits about the blue overlay icon meaning "added") 回答1: The "+" means that TortoiseSVN was able to figure out the item's history, and has
