What is a DAT FILE and why won't iTunes convert it?

trying to get some old songs off of an old mp3 player and they are listed as .DAT files. iTunes says it is of unknown format and won't convert. is there a way in which to convert them myself on my computer?

Tends to be used for application specific data files. If it's on a media player it's probably control files used by the player - playlists, artwork etc. If you are cetain these represent media files then they may have been renamed by the player's application as part of some anti-copying feature.

What does MSVCR80.dll mean and why won't iTunes play

I made a mistake of trying to play music while doing an update. Now I can't open iTunes and I get the message "This application has failed to start because MSVCR80.dll was not found. Re-installing the application may fix this problem" It DOES NOT. I have deleted all the apple programs and things off my computer then re-installed them. It did not change the message I am getting. I am also getting the message that "iTunes was not installed correctly. Please re-instal iTunes. Error 7 Windows error 126" I have tried to restart it making it the administrator. It didn't help. What do I do now?

What is the thumb64segment.data file, and why so big?

Ok, I finally got my MacBook Pro (first mac) got all my photos approx.7-8k worth into iPhoto. Can someone tell me what are the:
thumb64segment.data
thumb32segment.data
thumbJPGsegment.data
files and why are they in hundreds of MB, and one is ~1.5GB?
Thanks

Thanks toad. You might be right about the color profile, I imported all my photos into iPhoto yesterday and I had left the add colorsync profile checkbox clicked--I'm still trying to figure out exactly what it does and if I should have done that in the first place.
As a side note, and while I have your attention (since you are so good at answering iphoto questions).
I have a Sony V1 camera, which I assume uses the RGB or the sRGB color profile. When I get home tonight, I would like to software calibrate my monitor to 2.2 gama and 6500k white point. What else do I need to do to make sure that my photos are the same accross the board with respect to colorsync/color profile.
I rarely print photos (never at home), usually through imagestation.com (maybe through apple's service from now on, but I doubt it). I understand that assuming these services dont discard the color profile embeded into the image file I send them, I should aim to send them the file with the same color profile as is used by their printers? correct?
Is there anything else I'm missing here?
Is there any other benefit to embeding a color profile into an image? Like, if I email the img to someone, will the image look the same on their screen? (I assume not, because they will a) not have the screen calibrated the same way, and b) well, I'm sure there's another reason.
PPS. I did the search on this group earlier today and read a bunch of threads on this, but I"m still not clear.
Thanks in advance,

What are these LAUNCH errors, and why won't they go away?

Hi guys,
Mucho thanks to anyone who can help me. Here's my problem:
I went into my Event List and deleted lots of hyperdraw volume automation from many regions, one region at a time. This is the first time I've done this, only reading today how to do it. Now I have two error messages constantly coming up. Neither stops occurring.
1.
When reopening the session, the error says this, caps and exclamation points included:
"LAUNCH Event without associated track found! Changed to track 1."
-I have to click "ok" for four of these.
2.
When trying to change the lengths of regions and a few other normal editing choices, the error says this:
"Tracknumber of LAUNCH too high!"
-I have to click "cancel" for eight of these, and I'm never allowed to do the editing.
So...
-What do these mean?
-How do I get rid of them?
-What is "LAUNCH?"
-Without knowing it, did I delete some Event info. in those lists that I shouldn't have?
Random info: I'm running a 47 track session with my audio preferences set to 48 tracks. The CPU handles the load fine, before and now, I'm just getting these errors.
Thank you!

I'm pretty much 100% sure that "LAUNCH Event" errors are associated only with MIDI tracks.
There's one situation I know by heart that will cause such a message and it has to do with joining folders that don't contain exactly the same track count/track assignments.
I would suggest that in order to get rid of the messages to try the following:
1. Open your song
2. Select the first of your MIDI tracks create a duplicate of that track (i.e., create a new track with the same MIDI assignment and then opt-drag the regions in your original region to the new track).
3. Delete the original track
4. See if you can now perform your editing operations on it. IF SO, repeat this procedure for the rest of your MIDI tracks.
Let me know if you try this out, and, how it goes.

What is an inode file and why is it in my lost and found?

I was llooking through a clone of an old hard drive and found a file called lost and found with an inode file. arent these files used for hacking? being that i am not a hacker, how can i find out where this file came from and if its necessary in the clone.It's on an external disk

Thanks Wade.
That did the trick, once I figured out the missing step. For other folks interested, to use an .acv file to adjust a curve:
Open the Curves Adjustment Panel > Panel Options drop-down menu > Load Curves Preset... > find & select the .acv file (on hard drive) in the "LOAD" window > click LOAD. The adjustment in the .acv file will be applied to the image and appear in the curves graph of the Curves Adjustment Panel. Slick.
Apparently, moving the .acv file to the "Curves" folder in the "Presets" folder allows this curve adjustment to be a permanent preset choice. It can then be found under the Curves Panel preset drop-down menu. Just look for the original .acv file's name in the list.

TS3992 When I try to back up my iphone onto icloud it won't do it and I get a message saying "The last backup could not be completed." What am I doing wrong and why won't it backup?

How do I get my iphone to backup?

Welcome to the Apple Community.
If your back up continually fails, you might try turning off back up on your mobile device (settings > iCloud > storage & backup) and then deleting the backup file from iCloud by swiping the backup file on the mobile device (settings > iCloud > storage & backup > manage…) and then turning back up on again.
Being able to back up to the cloud can be very useful, especially if you don't have access to a computer or have infrequent access to one, however unless you specifically need to use iCloud for back up, you will find backing up to iTunes significantly more convenient and possibly more reliable.

My mac won't read my external harddrive's videos that I took with my Nikon. Half the videos won't play, and those are .avi files. WHY won't they play anymore and how can i retrieve them?

My mac won't read my external harddrive's videos that I took with my Nikon. Half the videos won't play, and those are .avi files. WHY won't they play anymore and how can i retrieve them?

What exactly is your problem? Is it, (a) your Mac doesn't read your external disk, or, (b) you can't retrieve your videos, or, (c) you can't play them, or, (d) you were able to play them at one point, but not any more.
What version of Mac OS X are you using, what app are you trying to play your videos with, what happens when you do, and what error messages, if any, do you get?

Why won't iTunes allow my iPhone 5 and iPhone 6 to play 176.4/24 AIFF files created in December of 2014 and January of 2015, but will allow my iPhone 5 and iPhone 6 to play 176.4/24 AIFF files created before December of 2014?

When I buy and download high resolution music files (FLAC and DSD), I convert them to AIFF files and add them to my iTunes music library. Specifically, I have been converting DSD64 files to 176.4/24 AIFF files. These AIFF files (modified in some respects by iTunes) have been synched to my old iPhone 5 and new iPhone 6. Until December, every 176.4/24 AIFF file played as expected. In December, I purchased two DSD64 albums, which I converted to 176.4/24 AIFF files using AudirvanaPlus 1.5. These 176.4/24 AIFF files will not play on either iPhone. When I converted those DSD64 albums to 88.2/24 AIFF files, they played on both iPhones. In December, I also purchased several 192/24 FLAC albums and converted them to 192/24 AIFF files using Amarra HiFi. These 192/24 AIFF files play properly on both iPhones.
Why won't iTunes allow my iPhone 5 and iPhone 6 to play 176.4/24 AIFF files created in December of 2014 and January of 2015, but will allow my iPhone 5 and iPhone 6 to play 176.4/24 AIFF files created before December of 2014?

I have a similar problem and have spent three sequential days at the Apple Genius Bar before we were able to exclude most other possibilities and found that certain files (in my case all mp3s from CDs I own) that play just fine in iTunes 11.0.1 and that used to play in iOS 6.0.1 do not play in iOS 6.1. We restored the phone to factory settings and synced only a few of the music files that were problematic. They still did not play. We reproduced the problem on my iPad mini (iOS6.1).
Apple Telephone Support suggestion was to convert all mp3 files in iTunes to AAC (which according to Apple Website may degrade sound quality). No further suggestions or escalation but a recommendation to place comments on www.apple.com/feedback and, if there are enough complaints, someone at Apple might take an interest in this problem. Something has changed in iOS 6.1 where files that played on prior mobile system software no longer work.
Apple, please pay attention to this glitch with iOS 6.1.

How to design SQL server data file and log file growth

how to design SQL DB data file and log file growth- SQL server 2012
if my data file is having 10 GB sizze and log file is having 5 GB size
what should be the size in MB (not in %) of autogrowth. based on what we have to determine the ideal size of file auto growth.

It's very difficult to give a definitive answer on this. Best principal is to size your database correctly in advance so that you never have to autogrow, of course in reality that isn't always practical.
The setting you use is really dictated by the expected growth in your files. Given that the size is relatively small why not set it to 1gb on the datafile(s) and 512mb on the log file? The important thing is to monitor it on an on-going basis to see if that's
the appropriate amount.
One thing you should do is enable instant file initialization by granting the service account Perform Volume Maintenance tasks in group policy. This will allow the data files to grow quickly when required, details here:
https://technet.microsoft.com/en-us/library/ms175935%28v=sql.105%29.aspx?f=255&MSPPError=-2147217396
Also, it possible to query the default trace to find autogrowth events, if you wanted you could write an alert/sql job based on this
SELECT
[DatabaseName],
[FileName],
[SPID],
[Duration],
[StartTime],
[EndTime],
CASE [EventClass]
WHEN 92 THEN 'Data'
WHEN 93 THEN 'Log' END
FROM sys.fn_trace_gettable('c:\path\to\trace.trc', DEFAULT)
WHERE
EventClass IN (92,93)
hope that helps

Yes, the tone is available and checked in iTunes under the Tones library.
Yes, it is also listed under the Tones tab for my iPhone, but it is grayed out.
Yes, tones are selected under "sources" in General Preferences, along with everything else.
SyncTones was NOT selected under the Tones tab for my iPhone. I did so and it synced.

What is open data set and close data set

what is open data set and close data set,
how to use the files in sap directories ?

hi,
Open Dataset is used to read or write on to application server ... other than that i am not sure that there exists any way to do the same ... here is a short description for that
FILE HANDLING IN SAP
Introduction
Files on application server are sequential files.
Files on presentation server / workstation are local files.
A sequential file is also called a dataset.
Handling of Sequential file
Three steps are involved in sequential file handling
OPEN
PROCESS
CLOSE
Here processing of file can be READING a file or WRITING on to a file.
OPEN FILE
Before data can be processed, a file needs to be opened.
After processing file is closed.
Syntax:
OPEN DATASET <file name> FOR {OUTPUT/INPUT/APPENDING}
IN {TEXT/BINARY} MODE
This statement returns SY_SUBRC as 0 for successful opening of file or 8, if unsuccessful.
OUTPUT: Opens the file for writing. If the dataset already exists, this will place the cursor at the start of the dataset, the old contents get deleted at the end of the program or when the CLOSE DATASET is encountered.
INPUT: Opens a file for READ and places the cursor at the beginning of the file.
FOR APPENDING: Opens the file for writing and places the cursor at the end of file. If the file does not exist, it is generated.
BINARY MODE: The READ or TRANSFER will be character wise. Each time n characters are READ or transferred. The next READ or TRANSFER will start from the next character position and not on the next line.
IN TEXT MODE: The READ or TRANSFER will start at the beginning of a new line each time. If for READ, the destination is shorter than the source, it gets truncated. If destination is longer, then it is padded with spaces.
Defaults: If nothing is mentioned, then defaults are FOR INPUT and in BINARY MODE.
PROCESS FILE:
Processing a file involves READing the file or Writing on to file TRANSFER.
TRANSFER Statement
Syntax:
TRANSFER <field> TO <file name>.
<Field> can also be a field string / work area / DDIC structure.
Each transfer statement writes a statement to the dataset. In binary mode, it writes the length of the field to the dataset. In text mode, it writes one line to the dataset.
If the file is not already open, TRANSFER tries to OPEN file FOR OUTPUT (IN BINARY MODE) or using the last OPEN DATASET statement for this file.
IF FILE HANDLING, TRANSFER IS THE ONLY STATEMENT WHICH DOES NOT RETURN SY-SUBRC
READ Statement
Syntax:
READ DATASET <file name> INTO <field>.
<Field> can also be a field string / work area / DDIC structure.
Each READ will get one record from the dataset. In binary mode it reads the length of the field and in text mode it reads each line.
CLOSE FILE:
The program will close all sequential files, which are open at the end of the program. However, it is a good programming practice to explicitly close all the datasets that were opened.
Syntax:
CLOSE DATASET <file name>.
SY-SUBRC will be set to 0 or 8 depending on whether the CLOSE is successful or not.
DELETE FILE:
A dataset can be deleted.
Syntax:
DELETE DATASET <file name>.
SY-SUBRC will be set to 0 or 8 depending on whether the DELETE is successful or not.
Pseudo logic for processing the sequential files:
For reading:
Open dataset for input in a particular mode.
Start DO loop.
Read dataset into a field.
If READ is not successful.
Exit the loop.
Endif.
Do relevant processing for that record.
End the do loop.
Close the dataset.
For writing:
Open dataset for output / Appending in a particular mode.
Populate the field that is to be transferred.
TRANSFER the filed to a dataset.
Close the dataset.

Anver
if hlped pls mark points

Timeouts increased after we moved USR, SAP data files and TLogs to new SAN

We are having issues with timeouts after we moved our USR, SAP SQL Datafiles and SAP Transaction Logs from our old SAN to a new SAN.
Timeouts for SAPGUI users are set to 10 minutes.
We are running Windows Server 2003 with SQL Server 2005.
The SAP database has 8 datafiles with a total size of about 350GB.
Procedure we used to move SAP to new SAN:
1. Attached 3 new SAN Volumes
     -a. USR
     -b. Data Files
     -c. Transaction Logs
2. Shutdown SAP and SQL services
3. Alligned the new volumes with a 1024kb offset and gave the Data files and Transaction log volumes a 64kb allocation
    size. (The alignment and 64kb allocation size were not setup for these volumes on the old SAN)
4. Copied the 3 volumes from old to new.
5. Changed the new volumes drive letter to the drive letters of the old volumes.
     -a. I had to restart in order to change the USR volume.
     -b. Because of this I had to resetup the sapmnt and saploc shares.
6. Started SQL services and then SAP services and everything came up just fine.
The week before we had anywhere from 1 to 9 timeouts per day.
This week: Monday had 20 and Tuesday had 26.
On Monday we saw that MD07 was the only transaction that was timing out, but Tuesday had others as well.
The amount of users in the system is about the same. The amount of orders going in are about the same. No big transports went in right before we switched.
Performance counters that I know about for disk look a lot better on the Data Files.
- PAGEIOLATCH_SH ms/request is about 50% better
- Under I/O Performance in DBACOCKPIT:
- MS/OP is now anywhere from 5 to 30 - Old SAN: 50 to 300
- The Hit Ratio is over 99% - same as the old SAN
Looking at Wiley Introscope graphs:
- The "SAP Host: Average queue length" is about 30% to 40% lower then the old SAN.
- the "SAP Host: Disk utilization in %" is about the same.
Questions:
1. Did we do anything wrong or miss anything with our move procedure?
     a. Do we have to do anything in SQL since we changed volumes even though we kept the drive letters the same?
2. What other logs or performance counters should I be looking at?
Thank you,
Neil

Our new SAN Vendor is Compellent. They have been fantastic. I would highly recommend checking them out.
The reasons for the timeouts had nothing to do with the SAN...Well kind of anyway.
I decided to check t-code SM20 to see what users were doing when these timeouts were happening. What I found was the program R_BAPI_NETWORK_MAINTAIN was being called thousands of times in a matter of 10 to 15 minutes at random times through out the day. It would take up about 50 to 80 percent of the amount of programs being executed during these times.
So, I sent this information to our developers and they found out that R_BAPI_NETWORK_MAINTAIN was being called from another program that was looping thousands of times. The trigger to stop the loop wasn't happening fast enough. They made a change and we haven't seen the timeouts since.
I think that the performance increases allowed the loop to run faster which caused the slow downs and timeouts to happen more often.
Thank you to everyone for their help!
Neil
