Use Robocopy (Robust File Copy). NOTE: In Windows Vista and Server 2008 when you type: xcopy /? you get: NOTE: Xcopy is now deprecated, please use Robocopy. So start getting used to robocopy 🙂
All file systems are different, so there are a huge number of data structures that actually get used in file systems. Many file systems use some sort of bit vector (usually referred to as a bitmap) to track where certain free blocks are, since they have excellent performance for querying whether a specific block of … Read more
In general, one “registers” a new mount filesystem type by creating an executable mount.fstype. $ ln -s /usr/bin/vdbfs.py /usr/sbin/mount.vdbfs If vdbfs.py takes mount-ish arguments (i.e. dev path [-o opts]), then mount -t vdbfs and using vdbfs as the 3rd field in fstab will work. If it doesn’t, you can create a wrapper which does take … Read more
Limit just some files => pipe to Select-Object -first 10 Order in descending mode => pipe to Sort-Object LastWriteTime -Descending Do not list directory => pipe to Where-Object { -not $_.PsIsContainer } So to combine them together, here an example which reads all files from D:\Temp, sort them by LastWriteTime descending and select only the … Read more
Take a look at FUSE: http://fuse.sourceforge.net/ This will allow you to write a filesystem without having to actually write a device driver. From there, I’d start with a single file. Basically create a file that’s (for example) 100MB in length, then write your routines to read and write from that file. Once you’re happy with … Read more
__file__ as others have said. You may also want to use os.path.realpath to eliminate symlinks: import os os.path.realpath(__file__)
How you approach this is going to depend a lot on how frequently you’re writing. If you’re writing a relatively small amount of text fairly infrequently, then just use a static lock and be done with it. That might be your best bet in any case because the disk drive can only satisfy one request … Read more
opendir(D, “/path/to/directory”) || die “Can’t open directory: $!\n”; while (my $f = readdir(D)) { print “\$f = $f\n”; } closedir(D); EDIT: Oh, sorry, missed the “into an array” part: my $d = shift; opendir(D, “$d”) || die “Can’t open directory $d: $!\n”; my @list = readdir(D); closedir(D); foreach my $f (@list) { print “\$f = … Read more
As far as I can see (1) (2) (3) (4), the way JDK7 does it, is by calling GetFileInformationByHandle on the files and comparing dwVolumeSerialNumber, nFileIndexHigh and nFileIndexLow. Per MSDN: You can compare the VolumeSerialNumber and FileIndex members returned in the BY_HANDLE_FILE_INFORMATION structure to determine if two paths map to the same target; for example, … Read more
If you only need to check extensions (i.e. no further wildcards), why don’t you simply use basic string operations? for root, dirs, files in os.walk(directory): for filename in files: if filename.endswith((‘.jpg’, ‘.jpeg’, ‘.gif’, ‘.png’)): pass
