Get file offset on disk/cluster number

久未见 提交于 2019-11-28 13:51:57
I need to get any information about where the file is physically located on the NTFS disk. Absolute offset, cluster ID..anything. I need to scan the disk twice, once to get allocated files and one more time I'll need to open partition directly in RAW mode and try to find the rest of data (from deleted files). I need a way to understand that the data I found is the same as the data I've already handled previously as file. As I'm scanning disk in raw mode, the offset of the data I found can be somehow converted to the offset of the file (having information about disk geometry). Is there any way

Mac OS 默认是不支持NTFS格式的移动硬盘或U盘。Tuxera NTFS 这款应用就是为了解决这一问题,网上下载说是破解版,日了狗了,点击激活跳转购买界面,内心几万个草泥马飞过,免费体验15天,体验后想卸载,还不能完全卸载,顽固性堪比病毒,不建议大家下载。每次插入优盘弹出 完全卸载方法如下: 终端下执行如下命令: sudo rm -rf /Applications/Tuxera\ Disk\ Manager.app sudo rm -rf /Library/Application\ Support/Tuxera\ NTFS sudo rm -rf /Library/Filesystems/fusefs_txantfs.fs 此过程需要输入密码,现在测试一下,如果不提示,证明已经完全删除,在此,恭喜你完全卸载了。 如果还有提示,那证明删除失败了,没关系还有终极大招: 终端输入:cd /Library/Filesystems 查看当前文件:ls sudo rm -rfv tuxera_ntfs.fs这个命令可以看到删除过程执行完这一步估计就可以完全删除了,如果还提示,那就按照这个步骤进入另外两个文件夹找到对应文件删除即可 来源: https://www.cnblogs.com/chenzxl/p/11407503.html

NTFS for Mac支持Mac拷贝文件到硬盘

不问归期 提交于 2019-11-28 10:04:34
 简单来说,Mac不能拷贝文件到硬盘中,实际上是由于该硬盘为NTFS文件系统,而Mac对NTFS文件系统的磁盘只有读取的权限,所以想要拷贝文件到硬盘中是无法完成的。   尽管这是由于Mac操作系统本身的兼容性造成的,我们在使用的过程中也无法避免,但可以通过其它方式解决这一问题。解决Mac对NTFS文件系统磁盘产生的问题最好的方法就是在Mac上安装NTFS for Mac软件,通过这款 Mac读写工具 全面读写磁盘。   Paragon NTFS for Mac是Mac读取、写入外置移动硬盘最佳解决方案。只要在Mac操作系统中安装这款软件,它会如同插件一般不用手动操作支持Mac系统实现操作。   图:NTFS for Mac界面   在软件的界面中包含几项基本设置,这些设置的使用不只针对NTFS文件系统,其他磁盘也可进行设置,进行常规管理。   NTFS for Mac四大特性:   (1)支持Mac写入NTFS   帮助Mac第一时间里实现读写、修改、访问Windows NTFS硬盘、U盘等外接设备的文件,直接避免了磁盘使用过程中产生的麻烦。   (2)安全传输文件   数据文件的安全传输是我们非常看重的,必须保证文件高速传输外接NTFS硬盘,并确保数据的安全性和完整性。   (3)操作简单实现快速   由于软件安装在Mac中相当于插件一般,只要成功安装便能迅速实现操作

Finding a set of file names quickly on NTFS volumes, ideally via its MFT

a 夏天 提交于 2019-11-28 09:29:01
I am in the middle of writing a tool that finds lost files of an iTunes library, for both Mac and Windows. On the Mac, I can quickly find files by naming using the wonderful "CatalogSearch" function. On Windows, however, there seems to be no OS API for searching by file name (or is there?). After some googling, I learned that there are tools (like TFind , Everything ) that read the NTFS directory directly and scan it to find files by name. I would like to do the same, but without having to start from scratch (although I've written quite a few disk tools in the past, I've never had the energy

Encountering a FileSystemRights value that isn't defined in enumeration

一曲冷凌霜 提交于 2019-11-28 09:20:09
I've written an application that examines all of the file system permissions on a directory. A directory has a number of access rules (of type FileSystemAccessRule ). Each access rule has a property FileSystemRights , which is a flag enumeration. When running this, I keep encountering a FileSystemRights value of 268435456 (which comes to 0x10000000 in hexadecimal). This value just doesn't appear in enumeration! It's actually higher than the highest single flag value ( Synchronize , having a value of 0x100000 ). Does anyone know what this is? See http://cjwdev.wordpress.com/2011/06/28

How do you deal with lots of small files?

这一生的挚爱 提交于 2019-11-28 05:21:53
A product that I am working on collects several thousand readings a day and stores them as 64k binary files on a NTFS partition (Windows XP). After a year in production there is over 300000 files in a single directory and the number keeps growing. This has made accessing the parent/ancestor directories from windows explorer very time consuming. I have tried turning off the indexing service but that made no difference. I have also contemplated moving the file content into a database/zip files/tarballs but it is beneficial for us to access the files individually; basically, the files are still

winXP也能纯DOS启动

三世轮回 提交于 2019-11-27 23:30:37
  安装了Windows XP/2000或更高版本后,要想启动到纯DOS模式下,一般只能借助软盘、U盘、光盘等。没想到笔者在网上搜到一款能 修改Windows 2000/XP启动菜单的工具软件,有了它,启动时就能选择进入纯DOS模式了。 好东东不敢独自受用,特共享出来。   使用方法   安装后,如果你有兴趣的话,可查看一下系统中的Boot.ini(默认位置是c:\)文件。已改成了以下的内容:   [boot loader]   timeout=6   default=multi(0)disk(0)rdisk(0)partition(2)\WINDOWS   [operating systems]   multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Microsoft Windows XP Professional" /fastdetect /NoExecute=OptIn   C:\WINDOWS\arboot\dos\ar.BIN="矮人工作室纯DOS模式"   C:\WINDOWS\arboot\di\dos.BIN="矮人工作室备份恢复"   这样的改动有什么作用呢?   启动时生成启动菜单,且在原有启动菜单的基础上增加两项:   其一是“矮人工作室纯DOS模式”   其二是“矮人工作室备份恢复”   当然

There is in Windows file systems a pre computed hash for each file?

谁说我不能喝 提交于 2019-11-27 23:02:04
I want to search a file duplicate by its hash. For performance purposes I want to know if there is a stored hash/checksum for each file in NTFS/FAT file systems. If there is, I don't have to compute them all to search my file. If there is, how to access it using .NET? If it helps, it will be JPEG files. Do they have a checksum? There is no such thing. Windows does not store a hash for each file. As Jader Dias suggests, there are checksums for EXE's and DLL's but these are not the droids you are looking for. Note that even if you had such a hash, it still does not guarantee uniqueness. If you
