Linux has a reference-count mechanism, so you can delete the file while it is executing, and it will continue to exist as long as some process (Which previously opened it) has an open handle for it. The directory entry for the file is removed when you delete it, so it cannot be opened any more, … Read more
If you want to force the file to be empty then you want to use the ‘w’ flag instead: var fd = fs.openSync(filepath, ‘w’); That will truncate the file if it exists and create it if it doesn’t. Wrap it in an fs.closeSync call if you don’t need the file descriptor it returns. fs.closeSync(fs.openSync(filepath, ‘w’));
Path class introduced in Java 7 adds new alternatives, like the following: /** * <pre> * Checks if a string is a valid path. * Null safe. * * Calling examples: * isValidPath(“c:/test”); //returns true * isValidPath(“c:/te:t”); //returns false * isValidPath(“c:/te?t”); //returns false * isValidPath(“c/te*t”); //returns false * isValidPath(“good.txt”); //returns true * isValidPath(“not|good.txt”); //returns false … Read more
I think you are right in all. The difference is easy to see if you follow the steps needed when booting: initrd A ramdev block device is created. It is a ram-based block device, that is a simulated hard disk that uses memory instead of physical disks. The initrd file is read and unzipped into … Read more
See http://msdn.microsoft.com/en-us/library/aa365247(VS.85).aspx This explains that Unicode versions of Windows APIs have higher limits, and how to enable that.
Use Process Explorer from the Sysinternals Suite, the Find Handle or DLL function will let you search for the process with that file open.
Call Path.GetFullPath; it will throw exceptions if the path is invalid. To disallow relative paths (such as Word), call Path.IsPathRooted.
I think the advantage is really that you reduce the amount of data copying required over traditional methods of reading a file. If your application can use the data “in place” in a memory-mapped file, it can come in without being copied; if you use a system call (e.g. Linux’s pread() ) then that typically … Read more
Copied from http://technet.microsoft.com/en-us/library/cc750354.aspx What’s FAT? FAT may sound like a strange name for a file system, but it’s actually an acronym for File Allocation Table. Introduced in 1981, FAT is ancient in computer terms. Because of its age, most operating systems, including Microsoft Windows NT®, Windows 98, the Macintosh OS, and some versions of UNIX, … Read more
The text after the colon is an identifier for an “Alternate Data Stream”. ADS is used to store meta-information about the file. For example, the Zone identifier stores whether the file was downloaded from the internet. Some specific info about URL Security Zones, Zone.Identifier Stream Name See also Technet, Heysoft and this article about alternative … Read more
