问题 An NTFS directory is open in a bash shell. what command will recursively truncate all filenames in a directory to the 255 character limit required for ext3? 回答1: If you have access to a Windows shell, you can use: @echo off setlocal EnableDelayedExpansion REM loop over all files in the cwd for /f %%a in ('dir /a-d /b') do ( REM store this filename in a variable so we can do substringing set ThisFileName=%%a REM now take a substring set ThisShortFileName=!ThisFileName:~0,255!

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 8 years ago . Improve this question I need to construct a SDHC card (FAT32) with a directory where I have chosen the short and long filenames independently. E.g. short filename MYDIR but long name i am a cool name. yeah. check out the awesomeness. Based on Wikipedia, there is no mandatory correlation between the two names, so

问题 So I'm using an STM32F407 and trying to write to an SD card with FATFS. I have used the CubeMX to generate the code for both the FAT layer and 4bit SDIO configuration software. I have added the following code to main to test whether the code works. UINT bw; f_mount(&FatFs, "", 0); /* Give a work area to the default drive */ /* Create a file */ if(f_open(&Fil, "newfile.txt", FA_WRITE | FA_CREATE_ALWAYS) == FR_OK) { f_write(&Fil, "It works!\r\n", 11, &bw); /* Write data to the file */ f_close(

虚拟磁盘空间不足虚拟电脑运行发生错误的原因及解决

我用virtualBox装了一台Centos虚拟机,20G空间的动态扩展的虚拟硬盘,今天突然提示错误: 虚拟电脑运行发生错误! 详细的错误信息显示在下面. 你可以试着修复这个描述的错误并恢复虚拟电脑的运行. The I/O cache encountered an error while updating data in medium "ahci-0-0" (rc=VERR_DISK_FULL). make sure there is enough free space on the disk and that the disk is working properly. Opera tion can be resumed afterwards. 错误 ID: BLKCACHE_IOERR 严重: 非致命性错误 虚拟磁盘文件.vol约4G大小,但剩余物理磁盘空间还有80多G足够用了,这是怎么回事呢? 我查了查资料,发现了问题,我的电脑的文件系统是FAT32,支持的最大文件为4G,这正好与虚拟磁盘文件.vol的大小相符,当虚拟磁盘因需要动态扩展时,由于FAT32最大支持4G文件,所以导致虚拟磁盘无法扩容,所以VirtualBox出现上述错误,提示空间不足。 解决思路: 解决思路就是将FAT32文件系升级为NTFS文件系统即可,通过命令执行转换后,不影响磁盘上现有的数据。注意

Unicode filenames on FAT-32?

问题 As far as I understand - NTFS supports Unicode filenames (UTF-16 as Micorsoft claims?). But official MSDN documentation is very vague regarding what codepage(s) is used to store filenames (filepaths) on FAT-32. Here it says that OEM code page (CP437 I assume) is used to store filenames: http://msdn.microsoft.com/en-us/library/windows/desktop/dd317748.aspx But here it turns out that there can be different OEM codepages with CP437 being one of them: http://msdn.microsoft.com/en-us/library
