Windows 7 problem with folder of .MTS files
Using Linux (Mageia-5) I copied some .MTS video files to a Christmas
visitor's USB flash drive to take home to her Windows 7 to play back. Checked that they played back OK under Mageia (VLC). But when I tried it on my Windows 7, the system denied the existence of the whole folder on the flassh drive (though no such problem with a folder of.jpg files on same flash drive.) [Then tried with a different folder name, but this time it said the folder was empty...] Anyone know of a way to persuade Windows 7 to play ball here, please? [Is converting all .MTS to .MOV the only way?] -- /\/\aurice (Replace "nomail.afraid" by "bcs" to reply by email) |

[Is converting all .MTS to .MOV the only way?] Sounds like a permissions issue. Take ownership of the folder and inherit ownership onto all child objects. Then set all permissions for the Everyone pseudo-account and also recurse or inherit the permissions onto all child objects. Easier to get Take Ownership. It adds a registry entry that runs the the takeown.exe and icacls.exe command-mode programs to take ownership and change permissions to All while recursing through the child objects. You could run the same commands from a shell (with admin permissions) but the registry entry with the command line is much easier. After install, open Windows Explorer, right-click on a folder or file, and select Take Ownership. https://www.sevenforums.com/tutorial...-shortcut.html Does mean, however, the object is visible in Windows Explorer so you can right-click on it to select Take Ownership. Did you check the file/folder attributes using the attrib.exe command in an admin-level shell (cmd.exe)? For a folder object, be sure to include the /D switch. Run "attrib /?" to get help. |

In one of my checks on W7 with the .MTS folder, it offered to 'fix it', and after checking the result I found that it had simply changed all the "*.MTS" to "*.CHK" and renamed the folder "FOUND.000"! To confirm this, I converted one of the .MTS files to .MOV, put that in a new folder on the flash drive, and plugged that into W7. Result: It found that folder and agreed the file was there, then played it back normally... So now I'm going to similarly convert all the other MTS files and put that on the flash drives as a replacement video folder for the visitor to take home. -- /\/\aurice (Replace "nomail.afraid" by "bcs" to reply by email) |

No, it did not change the extensions of the files. CHK files are recovered file fragments due to a corrupted file system. chkdsk could not ascertain for sure to which original file an orphaned cluster belongs so it reallocates the cluster into the file system giving it a generic fileXXXX.chk filename. CHK files are lost/orphaned fragments of files that are protected from overwriting by allocating them to new .chk files in the existing file system. You should run 'chkdsk drive: /r' on that flash drive. It has a corrupted file system, or had a corrupted file system if the "fix" was to run chkdsk. https://www.howtogeek.com/282798/wha...le-in-windows/ Note that chkdsk might fix problems now but flash drives operate differently than do magnetic media. If the reserve space is not getting used to mask bad sectors on the flash media so no bad ones are ever found, the flash drive is going bad. The firmware inside the flash drive responsible for wear levelling and masking should make the drive look always look good until the reserve space gets used up, there's no further space for masking bad memory blocks, and the drive catastrophically fails. If a flash drive starts to go bad, chkdsk might be a temporary cure but I'd get the files that I could off that drive and discard it. https://www.raymond.cc/blog/how-to-c...b-flash-drive/ You can find all sorts of flash drive test tools. Most will write gobs of data to the drive. Flash drives have a maximum number of write cycles and such testing reduces their lifespan. Because flash has a limited write cycle durability, they will die. Sometimes suddenly, sometimes getting flaky but will get worse and then die suddenly. If you write a lot to flash media, consider it disposable media. If chkdsk fixes a flash drive, hopefully it was a logical structure problem only in the file system. If the errors were due to media defects, look at getting the files onto different media. You might also consider what file system is on that flash drive. FAT has no error recovery for files that were left open when the OS crashed or the processes were killed that had files open on that media. NTFS includes journaling which can be used to rebuild the cached/buffered data that failed to get written to the media. FAT is more portable but NTFS is safer. |

To further elaborate on what you wrote that I snipped for brevity, it's possible the user partially corrupted the drive contents by removing it from his Linux machine too soon. By that I mean, didn't tell his linux machine he was done with the drive and just pulled it. -- Please visit our moderators personal page: https://tekrider.net/pages/david-brooks-stalker.php Now for a cheeky message from our sponsors: What should you do if a girl sits on your hand?

Windows doesn't do that. I don't know of any OS off the top of my head that ignores a folder/directory because it contains files unknown to it. In one of my checks on W7 with the .MTS folder, it offered to 'fix it', and after checking the result I found that it had simply changed all the "*.MTS" to "*.CHK" and renamed the folder "FOUND.000"! That isn't Windows complaining about not knowing what to do with MTS files, it's complaining about file system issues. It thinks the file contents on the stick are corrupted. Did you tell your Linux machine you were done with the stick prior to removing it? Or, did you just pull it when you thought you copied the last file? To confirm this, I converted one of the .MTS files to .MOV, put that in a new folder on the flash drive, and plugged that into W7. Result: It found that folder and agreed the file was there, then played it back normally... That isn't confirming what you think it is. Probably just as well to convert the files to a more known container, but, aside from that; you didn't confirm windows itself has a problem with the original files. What you confirmed was that Windows had a problem with the file system present on the usb stick. -- Please visit our moderators personal page: https://tekrider.net/pages/david-brooks-stalker.php Now for a cheeky message from our sponsors: Fat person: Nutritional Overachiever |

[Is converting all .MTS to .MOV the only way?] Do you use "Safely Remove" or in Linux, do dismounts before pulling USB sticks ? Maybe the file system took minor damage. When a file has an unknown extension or even no extension, that should not affect visibility. As for permissions, generally Linux does not apply an "unbreakable" permission to things it adds. Linux is not supposed to have support for SIDs on NTFS. The day Linux gets full support for every file system feature, is the day it'll become useless for maintenance. And I've not run into Linux changing some attribute bits either (like a Hidden attribute). Paul |

You confirmed that via chkdsk. Windows does not 'hide' files or refuse to access folders which you think contain files unknown to it. That's just not how it works. had no problems on Windows 7. Only the one with .MTS files... Happy with .MOV equivalents. You had some sort of issue copying those files from your linux machine over to that stick. To the point where Windows thought the folder contents were corrupt. Btw, just because Windows has trouble reading something doesn't mean that Linux will as well or that it'll be as severe on a linux system. With that said, just because your Linux machine thinks all is well with the world on the drive, doesn't necessarily mean it is. Linux 'cheats' in some respects. -- Please visit our moderators personal page: https://tekrider.net/pages/david-brooks-stalker.php Now for a cheeky message from our sponsors: Death is life's answer to the question 'Why?' |

One thing you might check: Look in the Registry under HKCR\.mts and see what's there. I have it marked as a video file. I suspect VLC did that. It's possible that .mts can also be something else that's hidden by default. (If hiding "hidden" files is enabled.) Why not just install VLC? I wouldn't put anything past Microsoft when it comes to trying to push their own media player. |
