Duplicate folders/files can't be deleted

Some duplicate folders/files may caused read error on the filesystem. After deleted those folders/files, the XSAN client seems work now.
However some duplicate folders/files still automaticaly gengrated and be seen on Server side(highlighted below).Those files won't be seen on client machine and are all unable to be deleted.
Can't you help us to figure out what's the problem?

If the OS is saying they're in use, they are. That message indicates that something on the boot drive is linked to the other disk or vice-versa. Quit all applications and try deleting again. If you get the same message, you'll have to track down what's open. One way is to launch the Terminal.app in /Applications/Utilities/, type in this command, hit the return key, and get the /dev/disk information for the attached disks:
df -h
This is an example of what you should see:
/dev/disk0s10 52162400 35274040 16888360 68% /Volumes/<name of other HD>
Then, enter this command, hit the return key, and peruse the output for the culprit(s) on that other drive:
lsof /dev/disk0s10
The only thing that should be listed is something like this, but that shouldn't prevent the disk from unmounting.

If there are other processes and open files, you'll have to stop the processes. Launch Activity Monitor, check the process number that's running (in this example it's Finder w/process #260), select it, click on the Quit Process button, and click on the Quit button in the dialog box that pops up. Now, try deleting the folders.

I am trying to download i tunes onto my pc but get an error saying that some old i tune files can not be deleted before reinstalling.

I am trying to download i tunes onto my pc (Windows XP) but get an error saying that some existing files can not be deleted to be re installed. I have tried several time but to no avail.

Many thanks, that's perfect.
The older version of apple software update cannot be removed. Contact your technical support group.
(1) Download the Windows Installer CleanUp utility installer file (msicuu2.exe) from the following Major Geeks page (use one of the links under the "DOWNLOAD LOCATIONS" thingy on the Major Geeks page):

Which files can I safely delete in my Pictures Folder/ iPhoto Library

Hello
Thanks in advance for any advice on the following. I am trying to free up some space on my Macbook Pro hard drive. In the Pictures/ iPhoto Library folder, I seem to have a lot of duplicates. At this folder level, I have series of sub folders with years 2002-2006 listed, and there is also a folder titled data, which also has subfolders 2002-2006. Can I safely delete one set of folders without losing my pictures?
Thank you
Jonathan

Johnathan:
In a word, NONE. Those are all necessary item for the operation of the library. Those files in the Originals folder are obviously the originals. Those in the Data folder are the thumbnails iPhoto uses to display in the main library window. The Modified files are those that you've editied, rotated, etc. To do any moving, renaming or editing of files directly from the folder is tantamount to committing the cardinal sin of iPhoto: Don't tamper with files in the iPhoto Library folder from the Finder.
What with the low cost of external FW HDs, they are a very cost effective way to protect and preserve important files. As you may know it's recommended to have a minimum of 10G free space for optimum performance of the system and applications. More if possible. You can use Monolingual to remove any language module you don't need (be sure not to select English or American English and DO NOT run any of the Architecture items). I saved nearly 900MB the first time I ran it.
Do you Twango?
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've written an Automator workflow application (requires Tiger), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.

Files can't be deleted b/c they're 'in use'

I'm being told that a couple of folders on another drive on my network, that I know aren't, are 'in use' and, thus, can't be deleted.
What's this from and how can I address it?

Reason why file can't be deleted?

When I want to delete a file via
file.delete()
the result is false. No IOException or other Exdeption just false. But what is the reason? When I try to delete the same file from another (simple test) application, i can delete the same file (result = true).
this happens for any new files in my directory. So, how can I find out the reason why the result is false and the file is not deleted?

yes, i'm pretty shure as i open the file to zip the
content to a new zip file, closing all the
input/output streams and then to a delete on the
original file. no exception, no error it just doesn't
get deleted and the return value is false. :-(
btw: the original file is not read only or something.
the files i want to zip are generated/copied on the
fly. and after processing, i want to zip them (which
works) and delete the original unzipped files (which
doesn't work).I know the feeling. But I'm pretty sure the file you want to delete isn't in the mood to getting deleted -:). Give it another try. Explicitly close is. Then delete it.

What files can be safely deleted?

I love my 400 MHz TiBook but its 10 GB hard drive is filling up. I have approx. 1.5 GB of free space left. What files that can be safely deleted? Can I delete extraneous printer files, modem files, packages, etc? I use MacJanitor to clean out caches and I don't have any music or photo files that might be causing the bloat. Also, before I delete anything I will back my hard drive up to a FW drive with SuperDuper.

Hi, Fred. You're wise to be thinking about how little free space you have left now, before the operation of your Powerbook is seriously impaired. But rather than just nibble away at the contents of your drive, which will only buy you a small amount of time before you're back where you started, you should be thinking about replacing your tiny 10GB hard drive with a larger one. You could easily get a 60GB drive for $50 plus the cost of shipping, and installing a drive in a Tibook is very simple — a 20-minute job at the outside. Then you'd just start up from the external FireWire drive on which you've cloned your 10GB drive, and use SuperDuper to clone its contents onto the new drive. The whole drive swap and data transfer, including the original cloning, could probably be accomplished in less than two hours. Then you wouldn't have to worry about hard drive space for a long time to come.

HELP! What server files can safely be deleted?

I think it is safe to delete C:\windows\tempdirectory
Can we safely delete C:\Program
Files\RoboEngine\Reserved\Web348881018
Thanks!

I do not know how server files are set up/deleted/added so
not sure exactly the process (using add/remove from control panel)
my engineers are taking - they are asking me, to save disk space,
if they can delete those old files.
Yesterday, through another source, I found out an entire set
of my 2007 project files might be stored on my server and will be
looking into that today also.
Thanks for the reply.

PSE9:Housecleaning "MyPictures" of duplicate Folders & Files

Hello!
I am currently running WinXPro and have just upgraded to PSE9 days ago. Problem; The XP, " My Pictures" folder is bloated with several thousand duplicate or saved/copies of files/folders that were placed there for safe keeping, salvaged from HD and program crashes over the past year, etc.etc. I have managed to reconstruct and "Reconnect" my image files in My Catalog/Organizer/PSE9 to my satisfaction. In the process I deleted several thousand of those redundant images in Organizer/My Catalog, which is now trimmed down and working well.
However, I did NOT "delete from the hard disk also" these files when I was housecleaning in the Organizer. I now realize that the " My Pictures " folder still has thousands of these redundant multiple duplicates that are still just sitting there, waiting to cause me grief again in the future.
Is there any SAFE way that I can houseclean (edit) the "MyPictures" folder in XPro of these redundant/deplicate/copies that PSE9 is not connected to and without causing a meltdown in Organizer ?
Thanx in advance.
Steve

A worthy idea!
So, I already have a current BackUp Catalog of PSE9 on an internal separate E:drive (plus a BackUp copy of C:MyPictures on E also). If I remove (empty) all of MyPictures in C:drive to an E:drive folder and then do a restore Catalog to the original location, this will replace ALL of the image files back to C:MyPictures that only PSE9 is connected to.
Mmmmmmmmmm ......... sounds too easy!!!
Thank you....... Steve

Pages '09 flat files can't be deleted but package files can

Hi all
If I save Pages '09 files in their default 'flat' format, then I can't delete them (empty trash command says files still in use, even if computer restarted and Pages closed), but if I save files as '09 packages, they are easy to delete. Anyone else come across this, or got an explanation?

Thanks to people for suggestions. Oddly, I've found a very simple solution... if I leave the items in the Trash for a few minutes, sooner or later they become deletable (possibly helped if the computer not doing anything else). Other files are deletable from the moment they hit the trash can, so there's still something different about the pages files. I wonder if another app or process finds it hard to let them go, or some odd thing like that. So it's turning into a minor oddity/ quirk rather than major problem. I'm still a bit puzzled, but I can live with the current level of weirdness (unless it gets worse...!)

What files can I safely delete?

My Premiere Pro CS2 Files are a mess!
Since I got into HD with my Canon HV20 I've been filling internal and external hard drives like no tomorrow. My TerraByte drives are full. I have thousands of files with extensions like: PRV, CFA, DEK, MACC, XMPSES and more. I don't know what I can delete and what I need to keep, collectively they are taking up an incredible amount of space.
Right now, I'm really hung up as I'm virtually out of space on one drive and CS2 can't conform (?) or render my movie.
How do Premiere CS2 users organize their files - what do they keep and for how long?
Ideas and methods would be much appreciated. Thanks.

If the project is finished and you never need to return to it. Export an uncompressed Master and archive it with the Source files and a .proj file. Use an external drive. (I use a e sata HD docking station for this purpose.)
Delete everything else.

What is a .BAK file & can I safely delete it?

In doing a workaround to solve a stutter problem in iMovie 4, my .iMovieProj files got completely out of whack. (Yes, I had more than one .iMovieProj file for my project. That's another story.) I had to go to my external backup disk to retrieve an .iMovieProj file. Because it would be better to keep the entire folder intact, rather than just put the .iMovieProj file into the current folder, I copied the entire project folder to my Desktop.
I deleted the current project folder and moved the Desktop folder into the iMovie folder, so now I have a previous, intact project folder, albeit a bit out of date, but at least all my videos & audios are there.
Anyway, as I updated my project, I noticed in the Movies window I had open on the desktop, that a file: <projectname>.BAK would appear & disappear. The project name was a bit altered. I think the file appeared & disappeared when I did a save, which I now do often.
What's going on? Should I delete this file when it shows again, or just ignore it & let iMovie 4 manage it, as apparently it's doing? On my last save, the file is not there, but it may show up, again. BTW, I noticed that the file decreased in size at one point. It's a small file, now, about 8KB as I recall.

Just let iMovie manage it.
When an application saves a document it's a bad idea to delete or empty the old one first and then write the new one. What if something goes wrong? A power outage or what ever.
The proper way is to keep the old (original) file until the new one has been completely written and THEN delete it. It seems as iMovie keeps the original under the <projectname>.BAK name until the new file is written.

Trc files: can they be deleted?

Our Oracle 10 installation has hundreds of *.trc files in its /dbdump directory. These files go back about two years. I would like to remove any that are not necessary for the day to day operation of the db.
Is it safe to remove any or all of these?
Thanks,
-=beeky

yes its very safe to remove them...in our env we remove all the trace files 15 days old..
find /u02/app/oracle/admin/CHIOPSWN/bdump -mtime +15 -print
to find the files that are older than 30 days
find $PWD -mtime +15 -print
same thing like above,if u r in the same directory
find /u02/app/oracle/admin/CHIOPSWN/bdump -mtime +15 -exec rm -r {} \;
to remove the files
find $PWD -mtime +15 -exec rm -f {} \;
same thing like above if u r in the same directory
find / -name "*.inst*" -exec ls -ltr 2>/dev/null {} \;
find with long listing
CHANGE LOCATIONS/PWD respectively

Question? Can you safely delete huge media cache files?

Dear Experts:
In working with PRE7 I found that almost all of my disc space was contained in my media cache folder and it was clogging up all my work. What is that file and can it be deleted without causing harm or losing work?
Tom

Tom,
This can depend a bit. If you have done any Rendering, those Render files can be safely eliminated. As mentioned above, the .CFA's and PEK files can also be eliminated (will be regenerated, if needed).
For housekeeping, I place all Scratch Disk files in the Project's folder hierarchy. This keeps everything together and below the Project's root folder. When I am done, I will just Delete everything in that Project. In my case, ALL Imported Assets are ONLY copies. I never work with originals, which are safely stored elsewhere. Basically, one click takes care of the cleanup.
If I am not sure that I am done forever with the Project, I will first use the Archiver (Project Manager in PrPro), and locate the "archived" Project on an external HDD for storage. I will archive ALL aspects, except for the Render files, including the .CFA's and .PEK's, just to save time, should I need to revisit that Project.
There are other files, that are possibly in the Project's root folder, such as when you Burn to Folder. You will then have the VIDEO_TS folder, with the necessary DVD-Video files. Once you have successfully burned that folder to DVD-Video, the VIDEO_TS (and all files), can safely be Deleted.
Hope that this helps,
Hunt
PS - UNTIL I am 100% certain, that I am done, I do not Move, Rename or Delete anything. When done, I often use the above mentioned Archiver, and then do major clean up.

How to know a priori if a file can be deleted?

My application requires that a collection of files be deleted. I currently loop through an array of File objects to be deleted, and invoke the delete() method on each object, i.e.
for (int i=0; i<collection_of_files.length; i++) {
returnval = collections_of_files.delete();
Problem: If one or more of the files has a "lock" on it, such as in Windows when some other process may be accessing the file, then those files can not be deleted, and returnval = false. How could I know before deleting ~any~ files in the collection, if some of the files can not be deleted? I would prefer not to actually delete any of the files in the collection, if one or more files can not be deleted because of a lock or any other reason. I have tried using SecurityManager to perform this a priori check on the deletability of a file, but no luck! Please advise.
thanks,
Ed

It tries to delete a temp file that doesn't exist, so
it doesn't delete anything in fact.Yes, the statement tempFile.delete() is not actually needed in the function isFileInUse. Other than that, the function isFileInUse does serve its purpose -- it determines true or false if there is a lock on a file. It does so by trying to rename the source file. If it can rename the source file, then we know there is no external lock on that file, and the function renames it back to what it was and returns false. This is a little tricky, but it works great. However, you would think there is a better way.
It was suggested also to try using the java.nio.filechannels.FileChannel class, which may be the proper way to go, but I haven't tried it yet. In particular, the method FileChannel.tryLock() returns "null if the lock could not be acquired because another program holds an overlapping lock."
