What is the best way to explore a hierarchical folder structure?

Hallo,
I need to access and navigate a hierarchical folder structure hosted in a MS SQL Server database. In particular there is a root folder containing several folders. Each child-folder contains further nested folders or documents.
For each item I need to retrieve the folder's (name, path, etc) and the documents (title, author, etc.) details that are retrievable from the DB fields. Afterwards I will use these data to create a semantic web ontology using Jena API.
My question was about which is the best way to proceed.
A collegue of mine suggested to use the "WITH" command of SQL Server to create and use a link list to navigate easily the structure, executing just one query rather than several (one for each level of the nested loops). However in this way the solution will work only with the SMQ Server database, while my goal is to achieve a more general solution.
May someone help me?
Thank you in advance,
Francesco

My goal is to create a documents library ontology achieving, from each element of the hierarchy (folder or document), some data (title, parent, etc.) and use them to "label" the ontology resources.
I will use a little of both approches in the following way:
1) I make just ONE query on folder table to get, from each folder, its path (eg. root/fold1/fold2/doc1.pdf), its ID and ParentID and ONE on the Documents table to get the containerID, title, etc.
2) I create as many Folder objects as the retrieved records and an HashTable, where the KEY = Folder.ParentID value and the VALUE = Vector<Folder>. I add then each object to the Vector relative to the same ParentID. In this way I have an Vector containing all the folders child of the same parent folder and I do the same for an HashTable keeping the documents contained in a specific folder.
3)I extract from the HashTable the root folder (whose ParentID is always "0" and whose ID is "1") than it is invoked the method appendChild() (see code)
     public static void appendChild(int ID, Resource RES)
          Vector<Folder> currFold = table.get(ID);
          for(int i=0; i<currFold.size(); i++)
               //Extract the child and crate the relative resource
               if(table.containsKey(currFold.getID()))
                    appendChild(currFold[i].getID(), Resource newRES);
In this way I go in depth in the hirarchical structure using a "left most" procedure. I made a test and the output is correct. However, such an approch must be done for about 4 level depth folders (around 30 in total) containing also documents and creating the documents library of a Project. Then I must process around 20 project to achieve for all of them such a documents library representation.
By the way, I do not have to mantein the HashTable content after I created the docs library ontology. Hence I use just one hashTable for ALL the projects and I flush it after I finish to do the loop for one project in order to save resources.
My question is: is right my approach or might I improve it in some way?
Thank you for every suggesion/comment.
Francesco

Can I recover data from a reformatted hard drive? I did not do a back up prior to talking to Apple Support and the guy having me delete the hard drive and start anew. My bad but is all lost??

Can I recover data from a reformatted hard drive? I did not complete a back up prior to talking to Apple Support and the guy having me delete the hard drive (10.5.8) and start anew (10.6.3). My bad but is all lost?? Years of very important information....

You will need to purchase reovery sofware such as such as FileSalvage
http://subrosasoft.com/software/filesalvage
You can download a demo copy that will tell you what it can recover
If you want to recover that you must pay for the software then
When you do the recovery, you will need another disk drive to receive the recovered files
Having install a new operating system on the disk after the retformat is going to gradually reduce the amount of data that this software will be able to recover for you

A message saying I had to restore my iPad to factory settings came up, can I recover data from previous back-ups?

Tonight, a message came up on iTunes came up saying I need to restore my iPad to factory settings came up. Is there any way I can avoid doing a factory restoration? If not, can I recover data from previous backups?

If you got the message that you need to connect to iTunes, there is no choice now but to restore the iOS software. Yes, you can restore from a backup after you restore the iOS software.
You can only restore now by connecting to your computer and using iTunes, and at the end of the restore process, you will be asked if you want to restore from your iTunes backup to which you will say yes and then sync your iPad as well. Syncing will transfer all of your apps, music, movie, books, photos etc, back to the device. If you do not backup and sync with iTunes, you can still restore from an iCloud backup after you restore the software in iTunes.

Can the contents of the Downloads folder be deleted?

Can the contents of the Downloads folder be deleted in order to regain storage space?

Hi KMess1948
The Downloads folder is just a convenient place to put stuff that you downloaded from various sources. It's contents can be deleted at will. You could of course create an archive on a separate harddisk or memory stick to keep for instance study material, or stuff that you would use more frequently. The rest of the stuff could be trashed at will.
I keep three achives, OS X and Combo Updates including and since SL, Documents, & important downloaded documents besides the normal backup stuff.
Download folder gets emptied regularly.
Have fun

Can I Organise using the original folder structure?

I spent some time organising my photos into sub-folders in my "my pictures" folder on my drive. When I imported them into Elements 9 I got a mass of thumbnails all listed in date order. Is there some way that I can organise my view in PSE by their orignal folders (as for example you can do with Picassa?)
Thanks for your help!

Many thanks for both answers and for rapid response! 99jon has solved the probalem and has given the solution I needed.
The reason for wanting to do it this way is that, having gone to the troble of doing the folder structure, it is a good starting point for anything else I may wish to do with PSE.

Script to copy data to new folder structure

I am working on a project where I need to migrate many TB's of data into a new folder structure.
I have exported the one of the folders including all sub-folder with treesize and exported it to excel.
So the source folder structure is in column A, which has several thousands lines and I have put the destination folders in column B.
Now I would like to script the data copy for every line the source folder is listed in column A and the destination folder is listed in column B.
This has to be done for all containing sub folders and files of course.
Has anyone got an idea how the script should look like ?
I can export the excel sheet to CSV, but then my knowledge stops unfortunately.

Win32 Device Namespaces
The "\\.\" prefix will access the Win32 device namespace instead of the Win32 file        namespace. This is how access to physical disks and volumes is accomplished directly, without going through the
file system, if the API supports this type of access. You can access many devices other than disks this way        (using the
CreateFile and
DefineDosDevice functions, for        example).

Migrate data to new folder structure

I need to migrate a lot of data to a new folder structure, one of the things I will have to deal with is file paths which are too long.
To copy the data I have made a powershell script which uses robocopy to copy all data.
Of course I do not want to have disruption in this process (or the least disruption possible), what can I do to prevent issues with long file paths ?
Is there an easy way to modify my script and detect issues with long file paths ?
What would be the way to go preventing many copy errors during the robocopy action and fix possible issues before starting ?

There are utilities out that (free / not free) that you can run and it will give you a report on which folders are too long. What I did was, I would take the results in the report and email it to an admin assistant or some type of key person in each
department, and they would fix the problem. Once I had them all done, then I would do the migration.

Can I recover data from an internal hard drive that I removed from my MB Pro?

A few months back my HD failed on my MB pro. I have since then replaced this HD with a SSHD. My question is can I recover this data from the old hard drive? I remember when I was at the Genius Bar one of the techs told me there was a company I could send the HD to and they could recover the data. Does anyone know of such a company?
Thanks

here is one of many companies. But it is expensive and not guaranteed. http://www.drivesaversdatarecovery.com/

Dear Apple: Can't recover data from iPad / no exploit for A5 bootrom

Dear Apple,
Looks like I'm not the only one who has had a failed upgrade to 6.1.3. Now my mother's iPad 2 is in recovery mode with 1000+ pictures lost in LaLaLand.
No recent backup, no iCloud.
I've done lots of research on how I can recover the data and the only possible way seems to be accessing the Ramdisk via SSH.
But there is no bootrom exploit for A5 devices, so it won't work.
Thanks Apple, I've lost photos of our family dog that passed this year, as well as photos from my grandmother's memorial service from this year.
I hope an Apple employee see's this...
Your process for upgrading iOS versions should be less prone to errors or failures. Required syncs or backups before upgrades should be required.
I could send my iPad to the main data recovery service Apple has partnered with... but I don't have $400 - $1200 to spend.
But even if I did, I would assume that only Apple has the power to access the data that is now in a digital vault, protected by their millions of dollars of revenue.
How can a top-leader in the consumer electronics industry let down so many of their loyal customers? Just google "recover data on iPad" or iPhone and you'll see that 1000's of people across the globe are having the same issue with iOS upgrades.
Please Apple, at least create a service to allow users to send in devices for data recovery. Only you have the power to "hack" into our devices.
Sincerly,
Forever lost memories?

Apple aren't here. This is a user to user forum.
You've lost your data because, as you said: "No recent backup, no iCloud." - that's your fault, no-one else's.
Backing up is necessary regardless of whether you are upgrading or not. Your iPad could've been stolen or damaged and you'd've lost the data the same. Apple provides you with at least 3 ways of retaining copies of your photos - you chose not to use them.
Call this a lesson learned in the consequences of not backing up as advised.

How can I recover data from a USERS01.DBF file?

So I had a Hard Drive die and that took out the OS and the Oracle RDBMS Installation (Oracle9i Enterprise Edition, 9.2.0.6.0 on WinXP). Fortunately most of the data in the database (9.5GB worth) was in the USERS01.DBF file which was on another drive and unharmed. I was also able to salvage the CONTROL01.CTL file, but everything else from the database is corrupted and irretrievable.
I've just setup a new machine with the same version of Oracle and I created a brand new database with the same SID as before. I then tried to do:
SQL> alter tablespace users offline temporary;
Tablespace altered.
(then I swapped the USERS01.DBF file with the original one and then tried to recover it)
SQL> recover tablespace users;
ORA-00283: recovery session canceled due to errors
ORA-01110: data file 9: 'F:\ORAHOME\ORADATA\MYDB\USERS01.DBF'
ORA-01122: database file 9 failed verification check
ORA-01110: data file 9: 'F:\ORAHOME\ORADATA\MYDB\USERS01.DBF'
ORA-01206: file is not part of this database - wrong database id
Is it even possible to do what I'm trying to? I had no backup of the USERS01.DBF file, but there should be some way to get at the data that is inside it...
any help or a pointer in the right direction is much appreciated.
thanks
-jeff

Whilst this isn't a direct answer, running any form of "recovery" will require archive logs, and it doesn't appear that you have archive logs related to this data file.
If you had your system.dbf file in addition to a control file and data file, I'd imagine might have enough to bring a database online using a "cold backup" type restore.
The specific error you show references the DBID in your data file does not reference the DBID in your control file. You don't appear to have restored your control file backup. This would make your existing .dbf files now not load, though a number of them can be rebuilt, not all of them can.

Can i recover data from an app to my new iphone ? (Sleep talk recordings)

Love the sleep talk app and i have some old recordigs i would like to recover. As they are not included when i synced the app to my new 4S, the only thing i can think of is restoring everything from my old iphone by syncing the old backup stored in itunes.
But i dont feel like doing that and i still dont know if that will me all the previous data and not just the apps themselves...

App data is part of the icloud and itunes backup. Backup your daughters phone.
I don't think you can save it to your phone, unless the movie app states that you can. Look at their support site.

SMART failure on internal SATA drive - Can I recover data or disable SMART?

Hi
One of my internal SAT drives (a Western Digital RE2 500gb drive) appears to be giving up the ghost and is reporting a SMART failure. The drive is mounting and shows that it has 100gb available but I can't access the data held in the missing 400gb.
I've run a TechTool report on it which has come back stating a failure on the following 2 points out of 15 tests:
• Reallocated Sector Counts
• Seek error rate
Appreciate that the drive is on its way out but is there anything i can do do retrieve the 400gb of data on it now before is completely dies? Can SMART be disabled on that drive to allow me to access it?
Any help would be appreciated.
Mark

It's not that SMART is preventing you from accessing it, the drive has had a physical failure. It may be possible to recover some data with a data recovery tool, like [Data Rescue|http://www.prosofteng.com> or [File Salvage|http://subrosasoft.com/OSXSoftware/index.php?mainpage=product_info&productsid=1], or you could send it off to a data recovery service, but there are no guarantees. If the data on that drive is not backed up, I'd guess you're about to learn a painful lesson about backups.
