ext[234] filesystems have a fixed maximum number of inodes; every file or directory requires one inode. You can see the current count and limits with df -i. For example, on a 15GB ext3 filesystem, created with the default settings: Filesystem Inodes IUsed IFree IUse% Mounted on /dev/xvda 1933312 134815 1798497 7% / There’s no limit … Read more
You are at a disadvantage. Windows Explorer almost certainly uses FindFirstFile/FindNextFile to both traverse the directory structure and collect size information (through lpFindFileData) in one pass, making what is essentially a single system call per file. Python is unfortunately not your friend in this case. Thus, os.walk first calls os.listdir (which internally calls FindFirstFile/FindNextFile) any … Read more
The following PowerShell code compares the file listings of two folders. It will detect renamed or newly created files and folders, but it will not detect modified data or different timestamps: $dir1 = Get-ChildItem -Recurse -path C:\dir1 $dir2 = Get-ChildItem -Recurse -path C:\dir2 Compare-Object -ReferenceObject $dir1 -DifferenceObject $dir2 Source: MS Devblog – Dr. Scripto 3rd … Read more
Use RecursiveDirectoryIterator in conjunction with RecursiveIteratorIterator. $di = new RecursiveDirectoryIterator(‘path/to/directory’); foreach (new RecursiveIteratorIterator($di) as $filename => $file) { echo $filename . ‘ – ‘ . $file->getSize() . ‘ bytes <br/>’; }
You can use WScript.ScriptFullName which will return the full path of the executing script. You can then use string manipulation (jscript example) : scriptdir = WScript.ScriptFullName.substring(0,WScript.ScriptFullName.lastIndexOf(WScript.ScriptName)-1) Or get help from FileSystemObject, (vbscript example) : scriptdir = CreateObject(“Scripting.FileSystemObject”).GetParentFolderName(WScript.ScriptFullName)
In Linux (you never mentioned which OS you’re on, so this could be relevant) you can create block devices from RAM and mount them like any other block device (that is, a HDD). You can then create scripts that copy to and from that drive on start-up / shutdown, as well as periodically. For example, … Read more

I know this is an old answer, but if anyone else stumbles across this question via Google like I did, here’s a more detailed explanation. If you want to make it so that search path contains the value of pwd at the time you set the search path, do: export PATH=$PATH:$(pwd) So, if pwd is … Read more
In VB.NET Dim directory as String = My.Application.Info.DirectoryPath In C# string directory = AppDomain.CurrentDomain.BaseDirectory;
As you have already found out, the difference between exists and isfile is the fact that the former returns True in case the given path is a directory or a file, while the latter only returns True if the path points to a file. Directories and files are quite similar from the technical point of … Read more
