Removing previous system files

Will I gain space on my HD by deleting previous system files.

You won't gain any space until you empty the trash, and that may take quite a long time. The last time I did it, I deleted one top-level folder at a time, then emptied the trash, to reduce the impact. Several of those sub-folders took quite a while.

Getting Iphoto files out of Previous System file

I upgraded to Leopard using the Archive choice. My iphoto and iweb files are in the Previous System file under User and won't load when I load the programs. How do I get them to load. How much free disk space do I need on my HD

You're going to have to change the permissions on that path to get access to the files there.
You can do this using the Get Info Window, just make yourself the owner of the folders in turn. When you get to your Home Folder, drag the foldes you want to the desktop. When you've that done post back and we can get you the rest of the way there.

Previous system file

Since installing Tiger, I note that a "Previous System" file has appeared. Do I need this? Also, do I need OS9 file? Not sure if I'm operating any programs with OS9. It was on this iMac when I purchased it new.

Previous System folder is created during an Archive and Install. If you're certain you'll never need any of these files (thousands) you can delete it.
The same with OS 9.

Are "Previous Systems" files important or can they be deleted?

There is a file in my the hard Drive of the MacBook entitled "Previous Systems.localized" which is taking up 9.72GB of space. Is this important or can I delete it to create space on the start up disk?

Hi -
Did you recently do an 'Archive and Install'? If so, that file may be leftover from your previous system. If things are working smoothly after a week or so I'd go ahead and delete the entire prev. system.

Can't delete Previous System File

Hi,
I did an archive and install and was left with a Previous System folder that is about 13G. I used "whatsize" app to move it to the trash where I then did a Secure empty trash. Trash can is empty, but when I run Whatsize again, the same previous system folder is still there, taking up 13G's of hard drive space. Any idea how to get rid of this file?
Thanks!

Previous System Files Lost After Re Install?

I recently had to blow out my system and re install my OS. I am pretty sure I checked the box to save the old system files in a directory and install the new one.
My question is, I did not have a most recent Time Machine backup of files from my desktop and had a new directory of pics there. Did I lose anything residing on the desktop directory when I re installed, or did it save in that "Previous System" directory, which as another question, I have no idea where to find that old system directory.
Thank you for your assistance!

Thanks, Kappy. Didn't understand you were pointing me to the PSF folder in your previous message.
Apparently, I must not have re installed the way I thought and the Mac HD OS Drive is clean with only the new OS, Applications files, etc. So, no PSF folder.
But, at least I know now!
Thank you for your help and good luck!

OK to delete "Previous Systems" file?

I noticed that after installing 10.5 (or maybe 10.5.1, because of the date), I have a folder called "Previous Systems" with a folder inside that called 2008-01-27_1835. Is it okay to delete this? It's taking 15 GB of space on my disk. Everything is working fine.

Hi J Micael;
If the Previous Systems folder was from either 10.5 or 10.5.1, then the chances of it being of any use are really slim. I think that deleting it will be a good thing.

Removing Previous Systems Folder after Leopard upgrade....Receipts get lost

After archive and install of Leopard I noticed the "Previous Systems" folder which also happens to contain ALL the receipts from Tiger days. It's over 3GB and I temporarily moved it to an ext hd. Is this OK??? I'm wondering how future update notifications will be handled if old receipts can't be found.
If I need to move the receipts back to my sys hd do I have to move all the other folders in Previous Systems folder back too, or just Receipts?

jimbo60640 wrote:
I thought future installers need to see these (old) receipts to determine update versions.
Yes, but the installer only needs to see 1 previous receipt not all of them. (i.e. once you have a receipt for 10.5 you no longer need all the receipts for 10.4). The receipts you will need have been copied to your receipt folder.

How to reconnect with previous system files

I recently had to reset my G4 and am now recovering my archived files. I'm at a loss for iPhoto(6), I reovered all my old files and I guess I have to re-import in to the library. The issue is that there are so many folders that I don't know what to import...orginals, modified, data.....????? Is there a "magic solution" that just reconnects the whole thing? I guess I could just re-import the "orginals" file but should I then rename it first? And should I then get rid of all the other "old" files first? This would be my least preferred option, as it would mean to re-adjust 3000+ pictures. Any help greatly appreciated! Frederic

Have a look inside your iPhoto Library Folder. Is there a file in there called library6.iphoto? If so then you do not need to import anything. Simply hold down the option (or alt) key and launch iPhoto, then choose 'Locate' and from there navigate to the library6.iphoto file. This should open your library.
If 1) You do not have this file or 2) it will not open, then you will need to create a new library and populate it.
To create and populate a new library:
Note this will give you a working library with the same film rolls and pictures as before, however, you will lose your albums, keywords, books, calendars etc.
Move the iPhoto Library Folder to the desktop
Launch iPhoto. It will ask if you wish to create a new Library. Say Yes.
Go into the iPhoto Library Folder on your desktop and find the Originals folder. From the Originals folder drag the individual rolls to the iPhoto Window and it will recreate them in the new library.
When you're sure all is well you can delete the iPhoto Library Folder on your desktop.
In the future, in addition to your usual back up routine, you might like to make a copy of the library6.iPhoto file whenever you have made changes to the library as protection against database corruption.

Where did my Previous System folder go?

I upgraded my G5 yesterday from 10.3.9 to 10.5. Everything works fine after the upgrade. But I can't find the Previous System folder that should be on my hard drive.
When I upgraded, I planned to do an Archive and Install and preserve user settings, but I never saw that menu in the installer (I missed the "Options" button, duh). After the upgrade all my user accounts and data were still on the G5, so I'm assuming the installer did an "Archive and Install -- Preserve User Settings" by default.
But I don't have a Previous System folder anywhere on my hard drive. Any ideas what happened?
BTW, I have a clone of my 10.3.9 system on an external hard drive. I am considering doing an Erase and Install on the 10.5.7 internal G5 volume and using Migration Assistant to pull my user accounts from the clone to the internal hard drive. But my 10.5.7 system isn't broken, so maybe I shouldn't try to fix it. :-D

But I don't have a Previous System folder anywhere on my hard drive. Any ideas what happened?
The default installation method preserves your user accounts, data, and applications, but deletes and/or overwrites the previous system files.

How do I use a backup of my previous system in migration assistant from an external hard drive?

I had to redo my system completely because Snow Leopard broke my Parallels and then when I went back to Leopard my entire system got all screwed up. So I archived and reinstalled Leopard. Transferred the entire Previous System file to my external hard drive then erased and installed a fresh install of Leopard then upgraded to Snow Leopard. Now I'm trying to restore my Previous System on my computer and I can get the Macbook Pro to recognize the external hd in Migration Assistant and in Disk Utility it appears I would have to transfer section by section. I'm trying to prevent that. I don't have money to buy Super Duper or anything else at the moment so Migration and Disk U. seem to be my only options unless you know of anything else.

How to repair corrupt \windows\system32\config\system files?

T61 will not boot to Win XP - says the \windows\system32\config\system file is missing or corrupt.
BIOS hardware test of disk drive passes. When I place a Microsoft Win XP disk to attempt a repair, the message says there is no disk drive detected. I assume this is due to unique Lenovo HDD drivers that are not on the Microsoft disk.
Is there a way to repair this file(s) without doing a full HDD reformat?
THank you.

You need to include the Intel Matrix Storage manager via Floppy disk while running setup-CD or change in BIOS "Config"-SATA" to compatibility.
Then you can repair windows but first backup the hard drive onto annother disk f.ex with Acronis True Image Home (Emergency CD).
Boot from XP Retail-CD
`select "Install"
select the drive with the found windows installation and "Repir"
Windows Setup removes the system files and replaces them from CD
after systemreboot you willneed to re-install all patches and updates

After archive and install--I have a previous system folder

Hello, I had a corrupted system file and I had to do an archive and install, which used the system discs I got with my laptop to reinstall OS X.
Now I have a previous system file on my hard drive. Is this still needed? Can i just delete it? What can I do?
Thanks

This is simply an archive of your previous system.
Although system was corrupt, you may be able to look through the folder and retrieve any data which you would like to keep.
But the answer is no, you definately don't need it.

Removing archived log files

Hello all,
Using Oracle 10g R2 ( 10.2.4.0) under UNIX Sun Solaris 10 , I have two rman backup types
1-L0 backup
2-L1 Backup ( Incremental cummulative)
Facts:
-Due to space pressure on archived log destination I'm trying to get less archived files possible under the archived log fs thus at any given time the archived log files destination contains archived log files aged no more than 22hours.
* The backup runs each day at 4PM and there is custom script that remove and compressed archived log files ( out of backup jobs windows) from midnight until 3:45PM
* From the above removal schedule task L0 or L1 backup will always have 24 hours worth of archived log files available during the backup.
-The Backup files Windows retention period is 22 hours meaning that each backup type L0 or L1 removes previous backup files aged more than 22hours.
-Tracking file is enabled
Target:
Knowing that our backup retention windows is 22hours.
Our next goal is to get less than 2 hours from 24 hours of archived log files available when L0 or L1 backup.
Would this affect L1 backup? and how?
Thank in advance for your response
Alex

AlexI'm not sure what you are talking about with Backup files Windows retention period ... 22 hours".
I don't know what you mean by "Our next goal is to get less than 2 hours from 24 hours of archived log files available when L0 or L1 backup."
If you are not taking your database backups with rman you are on shaky ground. The principles are simple. To recover your database from a failure, you will need to start with an L0 backup. The rman RESTORE command will then restore individual blocks from any applicable and available L1 backups. You would follow that with a RECOVER command, that would attempt to apply all necessary redo from available archivelogs. If the necessary archivelogs have been deleted, rman will attempt to restore them from a backup. You can use rman to backup AND DELETE archivelog files to keep the archivelog destination cleaned out.
I take an L0 backup once a week, an L1 the other 6 days, and archivelogs twice a day. The only time I've had a problem with the archivelog dest filling up is when some buggy code that has a loop goes into production and starts flooding redo.
Exactly how are you taking your database backups? If you are not using rman, then you are already on shaky ground.

How do I copy over files from "Previous System 1" to my current system

Hello.
I was having trouble with starting up my computer. I used a friend's computer to check Apple's Knowledge Base. The suggestion was to perform an Arhive and Install and to select the option of preserving my user and network settings.
I could not locate my Panther Install disc (my previous OS was 10.3.9). However, I did find my Jaguar 10.2 Install disc so I decided to use that instead (my disorganization is truly exasperating).
I thought once my system was again accessible (which it now is) I'd be able to reinstall Panther from the Archive even though I still can't locate my Panther Install disc. Is that possible?
I am, of course, having trouble using many of my 10.3.9 applications as they are incompatible with my currently loaded Jaguar 10.2 OS. I am unable to print, get my email, or use countless applications.
I'd sure appreciate help and suggestions as to how I might reaccess my 10.3.9 OS from the Archive so that I can avoid having to repurchase and reload Panther to get my original system back.
Is there a simple way to copy/move my previous system from "Previous System 1" back to my current system?
Thanks in advance for any suggestions.

P.S. I foolishly neglected to maintain a back-up of my data onto an external disk. If I can get things back to where they were, I've learned my lesson.

Lona:
Welcome to Apple Discussions.
As Kappy pointed out, you need Panther install disks to install Panther. However, you may be able to recover your data files from the Previous System Folder.
You can purchase Panther disks from applerescue. Your computer will support Tiger if it meets the minimum system requirements for Tiger.
Please don't hesitate to post back should you have further questions.
Good luck.
