问题 I am currently looking for a way to take a variable in batch and only parse out the filename. For example, I pass my batch file a -s parameter from another application which is subsequently set to my source variable. The source file variable typically contains something like: C:\Program Files\myapp\Instance.1\Data\filetomove.ext. I assume to read from the end of the variable until the first "\" and set the result to a new variable filename but I have not been able to use the "for /f" commmand

问题 public static boolean isValidName(String text) { Pattern pattern = Pattern.compile("^[^/./\\:*?\"<>|]+$"); Matcher matcher = pattern.matcher(text); boolean isMatch = matcher.matches(); return isMatch; } Does this method guarantee a valid filename on Windows? 回答1: Given the requirements specified in the previously cited MSDN documentation, the following regex should do a pretty good job: public static boolean isValidName(String text) { Pattern pattern = Pattern.compile( "# Match a valid

问题 String variable contains a file name, C:\Hello\AnotherFolder\The File Name.PDF . How do I only get the file name The File Name.PDF as a String? I planned to split the string, but that is not the optimal solution. 回答1: just use File.getName() File f = new File("C:\\Hello\\AnotherFolder\\The File Name.PDF"); System.out.println(f.getName()); using String methods : File f = new File("C:\\Hello\\AnotherFolder\\The File Name.PDF"); System.out.println(f.getAbsolutePath().substring(f.getAbsolutePath(

问题 I want to extract the file name from path string but i have difficulties with the GetFullPathName Function: WCHAR *fileExt; WCHAR szDir[256]; //dummy buffer GetFullPathNameW(g_fileName,256, szDir,&fileExt); //g_filename is filename with path string swprintf(szDestDir, L"C:\\Example\\%s", fileExt); MessageBoxW(hwnd,szDestDir,L"Debug",MB_OK); //debug message every time the message box displays "C:\Example\0" with 0 instead a filename, for example "text.txt". 回答1: I modified your code a little

问题 Is there any organization or articles that says we can or should not have multiple dots in filename? I'm really confuse if I should use dot in PHP files, I might break some rules or standards. 回答1: A filename with multiple dots does not break any PHP naming conventions, because file names are not PHP variable names; they belong to the OS really and PHP only sees them as strings. EDIT I looked around and found cases for multiple dots: version numbers and dates. There has been some discussion

问题 I have to build a project for encryption and decryption of files in AES-256. So, I have to encrypt files and those files could be of any format like text file, image file, video file or any kind of file with any format, And have to encrypt those files and store them on device with different format like *.anuj (extension name). Suppose I encrypted file and made new file with custom extension. While decryption that file how am I supposed to know that original file was text file or image or of

问题 I have multiple data files that are named after what they contain. For example machine-testM_pid-1234_key1-value1.log There are keys and values separated by - and _. Is there a better syntax for this? Are there parsers that automatically read these kinds of files/filenames? The idea here is that the filenames are human and machine readable. 回答1: There seems to be no standard file naming convention for key-values. 来源： https://stackoverflow.com/questions/10087079/is-there-a-standard-file-naming
