Slow file deletion

After upgrading to Snow Leopard, I noticed that file deletion takes a very long time - specifically about 2-3 seconds / file. It takes hours to delete a few thousand files. Anyone else experience with issue, or know solutions to it?
Thanks

I am also noticing a VERY slow emptying of my trash - often a few minutes even with only 2 or 3 items in the can. It's so slow that I get a progress bar each time and I've noticed that there are always more items listed as being deleted than are actually visible there. I've just put a single item in the trash (a .jpg image of only 197Kb) and the progress bar listed 6 items being slowly deleted.
I've de-selected the secure trashing option, but it doesn't seem to be speeding the process up and it's a feature I'd rather keep on, anyway. I hope this is fixed soon because it is a fairly obvious and noticeable bug that makes a mockery of what was touted to be a speedier user experience.

Okay, i have 2 bugs with maverick. First, when I delete a file within a window, the files deletes but the preview doesn't delete until I close the window and reopen it. Second, I work on a network of computers and the search feature is now buggy...

Okay, i have 2 bugs with maverick. First, when I delete a file within a window, the files deletes but the preview doesn't delete until I close the window and reopen it. Second, I work on a network of computers and the search feature is now buggy... When I search for a file, A) it asks me if it's a name, or it wont produce anything, and B), its slower than in prior OS versions and in some instances I have to toggle to a different directory and go back to my original directory in the search: menu bar or the search wont produce anything... Very buggy.

It appears to me that network file access is buggy in Maverick.
In my case I have a USB Drive attached to airport extreme (new model) and when I open folders on that drive they all appear empty. If I right click and I select get info after a few minutes! I get a list of the content.
It makes impossible navigate a directory tree.
File access has been trashed in Maverick.
They have improved (read broken) Finder. I need to manage a way to downgrade to Lion again.

Help with File.delete()

Hi All!
I am doing the following code:
String indexPath = "Y:/var/session/ZGCoVyCCcooSl1uHRYCAWg.idx";
File idxFile = new File(indexPath);
if(idxFile.exists())
System.out.println(indexPath + " exists.");
else
System.out.println(indexPath + " does not exist.");
boolean idxDeleted = idxFile.delete();
if(!idxDeleted)
System.out.println("could not delete " + indexPath);
if(idxFile.exists())
System.out.println("failed to delete " + indexPath);
When I run this code I get the following output:
Y:/var/session/ZGCoVyCCcooSl1uHRYCAWg.idx exists.
Which means that the file existed and the file is deleted. But, actually file is not deleted. When I try to manually delete the file, I get "sharing violation" error. I am running this code on a Windows 2000 server system and JDK1.4. I appreciate any help.
thanks,
Padma.

That IS strange. I don't have a Win2K server to test on, but I know Win2K Pro (at a client's site) seems incredibly slow at a lot of things, like when working with WinExporer. Someone told me it had to do with a configuration option. Perhaps there is something in the config telling your server to defer file deletes, e.g. "lock" the (to be)deleted file so no one can access it, mark it for deletion, but defer until later during a lull when all pending deletes can be batched at once. That would explain why you can see it, but not access it, and it goes away after some time. Then again, I might be TOTALLY out in left field... :(

I have an iMac purchased in May 2011. OSX Lion 10.7.3. I deleted backup file from the external hard drive which operates from Time Machine.
Now, the trash can will not empty some of the files deleted from the backup harddrive.
The trash contains-- File folder: "Core Services" which contains a locked file: "boot.efi".
It will not delete.
How do I get the trash can empty of these files?

Yes, the Old Master file has a folder for each year where I find all photos from that specific year. I am attaching a screen shot of the file.
In the meantime i have managed to download all photos (it did not download any video files though in mpg, avi, 3gp, m4v,mp4 and mov format) to a new iphoto library. Unfortunately the photos are quite mixed and often doubled up. I ma considering to purchase iphoto library which checks all duplicates in iphoto. this will save me a lot of time. What do you think?

File.delete() and File.deleteOnExit() doesn't work consistently..

I am seeing some odd behavior with trying to delete files that were opened. Usually just doing new File("file.txt").delete() would work. However, in this case, I have created an input stream to the file, read it in, saved it to another location (copied it), and now I am trying to delete it.
The odd thing is, in my simple application, the user can work with one file at a time, but I move "processed" files to a lower pane in a swing app. When they exit it, it then archives all the files in that lower pane. Usually every file but the last one opened deletes. However, I have seen odd behavior where by some files don't delete, sometimes all of them wont delete. I tried the deleteOnExit() call which to me should be done by the JVM after it has released all objects such that they don't matter and the JVM ignores any object refs and directly makes a call (through JNI perhaps) to the underlying OS to delete the file. This doesn't work either.
I am at a loss as to why sometimes some files delete, and other times they don't. In my processing code, I always close the input stream and set its variable to null. So I am not sure how it is possible a reference could still be held to the object representing the file on disk.

File.delete() not working properly

Hi Forum!!
I am trying with the below code :
File file = new file("path");
try{
if(file.exists())
System.+gc+();
file.delete();
System.+out+.println("Control in delete trx file after deletion"+ file.exists());
}catch(SecurityException se){
String msg= "Delete trx file if 3gttz file created : IO Problems";
Log.+error+(msg, se);
}file.exists() returns false But I when I check file, it still exhists with content 0 bytes .
Is there a way to remove the entire file from the directory rather than deleting only the
contents ? Need not to tell I did my initial search to solve the problem.
Thanks

Java.io.File.delete worked in 1.1, 1.2, 1.3 & 1.4, but not in 5.0

I have a logging utility I wrote originally in Java 1.0. A nightly housekeeping task runs which creates a ZIP file for the previous days log, then deletes the .log file. If I run this software with Java 5.0, the File.delete fails and the .LOG file remains on the disk. No exceptions are thrown. delete just returns false.
Any ideas?

to find a bug this basic! Each day I switch to a new log file, leaving the previous days file. I was never closing the old PrintStream... Jees... How embarrassing.

Slow Files Copy File Server DFS Namespace

I have two file servers running on VM both servers are on different physical servers.
Both connect with dfs namespace.
The problem part is both servers never have same copy speed.
Sometime very slow files copy about 1MBps on FS01 and fast copy 12MBps on FS02.
Sometime fast on FS01 and slow on FS02.
Sometime both of them slow..
So as usual I reboot the servers. Doesn't work.
Then I reboot the DC01 also doesn't work. There is another brother DC02.
After I reboot DC02, one of the FS become normal and another FS still slow.
FS01 and FS02 randomly. They never get faster speed together.
Users never complain slow FS because 1MBps is acceptable for them to open word excel etc.,.
The HUGE problem is I don't have backup when the slow FS days.
The problem since two weeks I'm giving up fixing it myself and need help from you expert guys.
Thanks!
DC01, DC02, FS01, FS02 (Win 2012 and All VMs)

Hi,
Since the slow copy is also occurred when you tried the direct copy from both shared folder, you could enable the disk write cache on the destination server to check the results.

Logs for File Deletion?

I have a situation where I don't want to recover a file... I want to see how it was deleted.
Is there any way to review file deletions via Apple log files or any other method? My research so far says no... but perhaps someone is craftier than I've proven to be.

An unfortunate circumstance to be sure. Out of curiosity is there any particular reason you can't use ClamXAV rather than NAV?
I suppose that if NAV has a log and nothing relevant is in the log, then you're at a loss to even know if NAV is responsible for the folder's mysterious disappearance. Maybe you have technically savvy cockroaches in the building that come out at night to play? An informational age version of Archie and Mehitabel?
This experience may be an impetus to install software that keeps track of what's installed or removed from a computer. Doesn't help much now but it would be useful in the future.
Oh, one thing comes to mind - file recovery software:

How to make JDS confirm file deletion?

I use the bash shell when logged in over SSH and I always set the following alias just in case I do something stupid:
alias rm="rm -i"Is there a similar setting for JDS that I can tell it to confirm file delete whenever I try to delete a file (i.e. popup a standard "Are you sure?" dialog box)?
Thanks!

By default JDS file browser "deletes" files to the trash can - a la windoze Recycle bin 8-( -
so it doesn't feel the need to double check as you can always reclaim the file from there.
Emptying the trash includes an "are you sure" which can be configured from the folders settings pane:
Launch->Preferences->Desktop Preferences->Folders and pick the "Behaviour" tab
If you mean you want the double check made in a terminal or console displayed within JDS, as opposed to using the file browser, then you need to place a suitable command in the configuration for the shell you're using e.g. .profile or .cshrc etc.
Regards,
Paul

File deletion in root and subdirectories.

Greetings,
I have a question regarding Batch scripting. I am trying to create a system maintenancing script which removes .TMP and .BAK files from all of my drives both subdirectories and directories above. Let's say the Batch script would be placed into "Folder3"
in the following internal drive address "C:\Folder1\Folder2\Folder3\Folder4\Folder5". And I want the batch script to remove files from folders 4 and 5 as subdirectories but also to remove files from C: Drive and folders 1, 2, and of course 3 itself
but without removing folders. And I'd like to apply this method to all drives simultaneously without a human user personally moving the script via cut/copy and pasting from drive to drive. The other alternative which can come into consideration is to create
a Batch File with any address location on the internal drive and when running this Batch file it'll create additional Batch Files on specified (multiple) drives at the very root of drives in the drive address of C:\ for instance, and initializes the required
file deletion process. Some of the folders require my Administrator priviliges therefore I'd like to create a code within the script that ask for user permission and says "Yes" but without actually asking from me as the user to click "Ok"
or "Yes" when running the script itself or to fully bypass the firewall. I have created the other part of the coding for deleting specified superfluous file types and in what way it's just the sub and above-directory part of it that gives me a pause
to proceed. Any help is greatly welcome or pointers. If my request would seem cluttered please notify me of it and I'll try to simplify it down, although I hope I wasn't too confusing with the elaboration.
Thank you in advance, even for the consideration.
Kind Regards.

Why file.delete() won't work?

I looked throught the forum and I have seen that my problem isn't the most uncommon one. I'm trying to delete a file using file.delete().But it always return false. I have used the file for reading(and sometimes writing) before but I have closed the stream, I have checked that many time ;).
This has me a little confused. The file ins't write protected either. Is there perhaps anyway to close all streams assosiated with a certain file?

     try {
            boolean success = (new File(currentFile)).delete();
            if (!success) {
               statusLabel.setText("Error");
            readPatients();
         catch (SecurityException se) {
            System.out.print(se);
         }Should work, shouldn't it?

Operations on file: Deleting and get size

Hi,
I'm triying to delete a file. I use the following code:
File found = new File (directoryOutputFileWriter+f);
boolean deleted = found.delete();But when I execute it the boolean deleted it's always false and the file is not deleted.
Then I try to get the size of another file in this way:
File produced = new File(directoryOutputFileWriter+file[0]);
long size = produced.length();but I receive a null value (the file exists and its dimension is over 0 of course).
Why?
How can I solve?
Thanks, bye bye.

Hello,
in my experience the absolute #1 source of astonishment with file operations is loose manual checking (mistyping or misreading).
I suggest you use those traces:
File found = new File (directoryOutputFileWriter+f);
System.out.println("File path is"+found.getAbsolutePath());
System.out.println("Does this file exists? "+found.exists());
System.out.println("Is this file really a file? "+found.isFile()); // You may not be able to delete a directory on all platforms
System.out.println("Is this file deleted now? "+found.delete());#2 is developers not reading the javadoc (that states that delete may not succeed), but I acknowledge you have read it, as you're investigating why it hasn't, and not complaining that it has.
#3 is people overlooking OS-specific file management. E.g. Unix-Linux-Window file permissions management all may let you read a file but not delete it (with the unices having a richer set of combinations than windows). The rules for directory deletion are different between Unices and Windows. Etc...

@Joachim: nice catch! Loose manual checking indeed (both on my part and on OP's)...
