Is there a software that will detect corrupt files and notify me?

A back up does no good if a file becomes corrupted, then the back up starts saving over the good file with a corrupt one! How can I know if a file has become corrupted with out opening it? I have thousands of files. Is there some sort of scanner I can run daily to make sure my files will open when I need them. Thoughts? Thanks so much!

Well, what does "corrupt" mean?
Exactly. In other words, "file corruption" is a very broad, generic, and catch-all term. Sure, there are utilities which can continually or periodically scan disks and automatically alert the user (and sometimes even correct) the kinds of "corruption" that pertain to the disk data tree which records and organizes the writing of files to your disks.
But that's an entirely different thing from the kind of "file corruption" that is specific to a particular software and its native file formats. A FileMaker database, for example, can become "corrupt" due to things ranging from bad practice to momentary network outage. The on-disk "file" itself may be perfectly fine, but its content just doesn't entirely "make sense" anymore to the application. That's why many applications (FileMaker included) provide their own built-in file recovery tools.
You can open a native AI file (or most any application-specific file) on your computer with a text editor, make some text edits in it, and then save it. Doing so can wreck the file in terms its usability in AI; but all the while it will likely be a perfectly valid file in terms of "a file on disk."
So assuming you're talking about the kind of "file corruption" which AI users frequently complain about when a file suddently can't be opened, or throws up some alert, I doubt you will find a background utility specifically designed to test the AI-native integrity of AI-native files.

  • I have an iMac which I had loaded Parallels and Windows 7.  I recently uninstalled both programs. How can I delete all related files?  Is there a program that will find related files and delete them?

    I have an iMac on which I had installed Parallels and Windows 7 so I could some of the creativity software I was used to. I recently uninstalled both Parallels and Windows. How can I clean up my hard drive by making sure stray files from those programs have all been deleted?

    If you followed these steps to uninstall Parallels (you simply drag Parallels to the Trash), that's all. Parallels is a quite clean application that does not create a lot of files in different folders.
    However, you may still have the virtual machines you created in Documents folder. If you want to remove them, open a Finder window, select Documents in the sidebar and remove the Parallels folder

  • Is there any software that will delete video after I crop in iMovie

    Ok, I've spent days reading posts and googling for answers. I'm ready to spend $$ if I need to. We're all aware of how iMovie won't let us delete unwanted video. I'm trying to fix a wedding video some hack did in SVHS. I got it from DVD to Video_TS to DV using MPEG Streamline and imported the video clips to iMovie. (By "video clips", I am mean the DV files.)
    There are 7 DV files from a 69-minute video. I am creating tons of smaller "clips" from these DV files - like 5 to 15-second clips - because I want to use transitions in between them.
    My understanding of what's happening in iMovie as I do this is as follows:
    - Let's say I begin with the first DV file that is 1.9 GB, about 10 minutes long.
    - I create a 10-second clip from that by (a) selecting my start and end points, (b) clicking Edit>copy, (c) clicking on the clip pane, (d) clicking Edit>paste.
    - Now I have a new 10-second clip.
    - But! I also have 1.9 GB of unused video behind that clip, right?
    - I repeat the process maybe 30 or 40 more times until I've edited the original 10-minute DV file (clip) and what do I have?
    - Do I have 40 10-second clips each with 1.9 GB of unwanted video behind it??
    As I said, with 7 DV files at 1.9 GB each that need to be sliced into multiple clips for transition effects, etc, this will shut down my MB quick. I've only done this with 3 DV files so far and I have 12 GB of HD space left. I will obviously not be able to finish the project this way. What a disaster!
    So here's the million dollar question -- Is there ANY 3rd party software that will allow me to slice these DV files into small clips and permanently delete the unused video?
    I don't care if I use something that "replaces" iMovie or something that works with iMovie. Like I said, I'm ready to spend the money to save the time, disk space, and aggravation. Note I worked in video production (many) years ago so I'm not afraid of something "technical" (editing concepts aren't new to me). However, I'm far from being an expert on what's out there these days.
    I should also note that the original wedding video (DVD) did not have any chapters or anything of the sort. The ONLY way I can edit this is to import the entire file as it was converted to DV. It's not like I can import only the video I want to use. I hope that makes sense. I do not have access to the source video either - only this pathetic DVD he calls a wedding video.
    Thanks in advance so much for any help. I never would've gotten this far without all the posts!

    - Do I have 40 10-second clips each with 1.9 GB of unwanted video behind it??
    Not to worry. When we Copy and Paste within a project, iMovie HD creates a new clip thumbnail for the Timeline/Clips pane, then simply adds a new pointer to the source video. The source material is not duplicated.
    When you Copy a clip and Paste a clip to a DIFFERENT project then Yes, the clip's entire source video file is duplicated. (When Copying between projects, be sure to Copy and Paste all the clips together so iMovie duplicates the source files just one time.)
    Next time, you might consider setting your iMovie 6 preferences to limit the length of imported clips to 3 minutes — or whatever duration you want. Then each imported clip will have its own source file. When you discard an entire clip its file will be discarded too, shrinking the size of the project.
    If you have no need to preserve the clips as clips you could export the project to a Full Quality movie that you import to a new project. Everything will arrive as a single clip, which may be okay here. Then discard your old project. The project will be smaller, containing just the stuff on the Timeline.
    If the Timeline contains most of the source material — just split into small clips — there may not be a lot of "extra" material in the project. To get an estimate of how large the Timeline really is, open the "Timeline Movie.mov" that's inside the Cache folder of the project in QuickTime Player. QT Player's Show Movie Info window will show the size of the material it represents.

  • I'm a Dropbox user and I migrate between my iMac and a Toshiba notebook.  Is there Apple software that will work on the notebook allowing me to open Pages, Numbers or Keynote documents that I've placed in Dropbox?

    I'm a Dropbox user and I migrate between my iMac and a Toshiba notebook.  Anyone know if there is Apple software that will work on the Toshiba that will allow me to open Pages, Numbers or Keynote documents when I access them in Dropbox? 
    Maybe I should just always export from Pages into Word  (and likewise for the other types) before I upload to Dropbox?  I hope not!!

    If you don't want to export files and consider the Microsoft formats to be your basic working format, then you need to consider either using MsOffice for Mac or LibreOffice instead of the iWork suite.
    You could always run a virtualised OSX on the Toshiba, but I don't think Apple will appreciate me telling you how to do that.

  • Is there HP software that will allow an Officejet 6500 E710n-z to work under OS X 10.9 Mavericks?

    My Macbook's currently running OS X 10.8.5 Mtn. Lion.  I've been hesitant to upgrade to Mavericks for fear of what it might break.  I just saw the
    posting by HP employee Vanricker, "Update - HP Scan application - Grayscale fix - OS X 10.9 Mavericks", at http://h30434.www3.hp.com/t5/Mac-Printing-and-Scanning/Update-HP-Scan-application-Grayscale-fix-OS-X... But it doesn't list the Officejet 6500 E710n-z.  It does, however, say it applies to the Officejet 6600 and 6700.  I'd have posted my question as a reply to that posting, but in the 8 months since that was posted, there have been 10 requests for further help that were posted as replies, and not a single one of them was answered.  So instead I'm submitting this as a brand new post in the hope that somebody knowledgeable at HP will notice my question.
    Can the Officejet 6500 E710n-z work with OS X Mavericks?  If so, do I need to download new software from HP?  If yes, what's the URL for that software?

    Yup, it will work with Mavericks.  Here is how I recommend you proceed:
    Uninstall the existing HP software using the 'scrubber' option:
    Go to Applications/Hewlett Packard/ click on HP Uninstaller
    Click on Continue
    Highlight your device on the left pane
    Press and hold Control + Alt + Cmd keys on the keyboard simultaneously while you click on Uninstall This IS the Scrubber Option, there is no button labeled "Scrubber"
    There will be a pop up that asks if you are sure you want to uninstall ALL hp software. (At this point, if you continue, any HP printers you have installed will need to be reinstalled)
    Click Continue and let it finish
    Download and install this: http://support.apple.com/kb/DL907
    Restart your Mac.
    Now reset the printing system:
    - Sys Prefs, Print & Fax
    - Right (control) click in the rectangle listing your printers and select Reset Printing System.
    WARNING - this will delete ALL of your printers!
    - Select the plus sign to re-add it. Look for the printer, select it and wait until the "Add" button becomes available. Click it.
    Do not install specific HP software for your printer.  Scan from the printer using the Image Capture app in your Applications folder.
    Click once on the scanner on the left side, then click on Show Details along the bottom. Along the right side you will see LOTS of options for scanning and saving.
    Say thanks by clicking "Kudos" "thumbs up" in the post that helped you.

  • Is there any software that will normalize sound volume?

    I don't want to use Sound Check to normalize my whole library, and my library is too large to modify the volume on a song by song basis. What I need to find is software that can normalize the volume of a playlist, both while playing it on my Mac, and also when burning a playlist into an mp3 disk. Does such a program exist for Mac???

  • Is it possible to connect to a Power Macintosh 8100/100 running v7.5.5 from a current PC via AppleTalk? If not is there any software that will allow me to?

    The question says it all. We are trying to add an old Power Macintosh 8100/100 v7.5.5 to our network. We tried using PC-MACLAN but it requires OS X.  Is there any way to get around this or is there any software available add this to our network?  Any help is greatly appreciated.

    Hi,
    If you wish to merely transfer files, one idea could be to have one ftp or web server on each machine, and then use appropriate clients (ftp programs or web browsers).
    TCP/IP software is available under System 7.5.5. The 8100/100 can use standard RJ-45 Ethernet cabling via a suitable adapter for AAUI-15 (such as the Apple Ethernet Twisted-Pair Transceiver M0437).
    For the Mac, the now free program NetPresenz could perhaps be of interest as a server solution.

  • Is there an application that will allow adding files to a "Burned Disk"?

    In the Finder, if I burn several folders to a disk, I can not add any additional files later, even though I've used less than 10% of the disk's capacity. Is there any way around this? Some other disk burning application?
    Patrick

    Take a look at: disco
    (free App)
    CD sessions, turned off by default, allow you to add more files to a disc that has been used before. Instead of erasing the data that is already on the disc (as is done with CD and DVD rewritable discs), it appends the new data to the existing data.
    Using Sessions
    Session CDs allow you to burn additional data to an already burned CD. After inserting a session disc in your mac, depending on whether or not you have set it to automatically add sessions to appendable discs, you will be able to burn additional data to the disc.

  • Can't iconvert SD600 files on mac book pro, apparently not compatiable.  What software can i download that will transcode the files so i can log

    I have the SD files on my mac book pro hardrive but they are not compatiable and i cannot view them. I want to edit the clips in FInal Cut Pro.  I think i need to downloadd some software which will transcode the files and then i can import into Final Cut Pro? Any suggestions greatly appreciated!

    Acorrding to the technical specs, it shoots mpeg4/h.264... However, I see other places mention it is MTS...
    Do you still have the original file structure intact? Or do you have just individual movie files? whats the extension? .MTS, .MPEG4, MOV?
    If MTS and you no longer have the original file sturcute intact, you need to use Clipwrap, if you do have the original files structure, you may be able to import using Log and Transfer....

  • An app that will convert VOB files into individual episodes?

    Hello,
    So I have a DVD that I converted a bunch of TV shows onto using Visual Hub. The problem is I get 18 hours but it converts into VOB files.
    Is there an application that will convert VOB files into MP4 format but make them into individual episodes?

    AndreTheGeek,
    Thanks, I did try it but maybe I'm doing it wrong. Think what I want is impossible. I want to take a VOB file that has like 5 shows on it and want the output of that to be 5 individual mp4's so I can pick and choose what I want to go on my ipod.
    I think you must have done it wrong.
    For a start. forget about VOB files - there's no need to mess around with them if you use Handbrake. Simply put your DVD in the DVD drive of your Mac and tell Handbrake to use that DVD as the source - it will help you with the rest of the procedure.
    You will find that Handbrake interprets the information on the DVD as individual episodes (top of the page, choose the "title" drop-down menu), giving you the running time of each one. Just choose a particular episode, give it an output file name and add it to the queue. Then select the next episode and give that a different file name. When you've finished, simply run the queue and it will convert them all into the individual files you've specified.
    If you find an episode that appears to be longer than all the rest, this is usually the one that contains all the episodes for the 'play all episodes' feature on your DVD. Leave that one out of the queue.
    It's not always obvious which episode is which (as they aren't always stored in the correct order on the DVD) so you can just give each file an arbitrary name for now, then watch the resulting mp4 files and name them appropriately at that stage.
    There is also a guide to ripping TV Shows for your iPod on the Handbrake website (with pictures) if you find my description confusing.

  • Is there a native app/software that will get my photos all the same size?

    I know how to do this with photoshop but I'm not sure if there is any Apple native app/software that will do this for me. 
    Lets say I have 5 photos of different sizes and I want them all the same size.  I know I could reduce them all in preview but that doesn't allow me to move the photo around and cut out stuff I don't want in it.  Or I could crop them in Preview but then they are not automatically all the same size. 
    The way it works in photoshop is:  I open up a new project that is the same size I want the photos to be.  Let say 900x644.  Then I copy one of the photos I want in that size (lets say it somewhat bigger) and when I paste it into that blank new project that is 900x644 I can move the pasted photo around to get it so what I want to fit into that newer smaller size is there.
    Is there any way to do this without special software on a regular Mac.  I'm trying to help a family member who doesn't really want to buy or learn a complicated graphics program.  They have iLife 11 BTW but I don't see a way to do it with iPhoto.
    Thanks for any ideas you may have!

    Use the Automator app (it's in the app folder) to resize a batch of photos:
