How can I open a tdms file and replace a subset of data then save that change without re-writing the entire file again?

Hi all,
Is it possible to open a tdms file and make a small change an an array subset then save the file without having to save the whole dataset as a different file with a new name? That is to say, is there something similar to "Save" in MS Word rather than "Save As"... I only want to change a 1D array of four data points in a file of 7M data points.
I am not sure if this make sense? Any help is apreciated.
Thanks,
Jack

You can use either one, but for your application, I would use the synchronous. It requires far less setup. When you open the file, set both enable asynchronous and disable buffering to FALSE to enable you to use synchronous with arbitrary data sizes.

I am unable to update my album art since I commenced using match (and after upgrading to Yosemite). How can I 'unembed' old cover art and replace?

I am unable to update my album art on my iMac since I started using Match (and after upgrading to Yosemite 10.10.3). A message advises that it's not possible to removed old artwork if it's embedded. How can I 'unembed' old cover art and replace?

Normally artwork recovered with iTunes is stored as a separate artwork file and iTunes refers to that file to display artwork when you click on a track. However, if you then copy the file to another player the artwork file is left behind and the track will not display the artwork on the other player. To get around this it is possible to embed the artwork in the music file itself so it always travels with the file. Artwork can be embedded by you or files from third party sources may arrive with embedded artwork. iTunes apparently now won't replace artwork for such files. You can accomplish this by completely deleting artwork for a file or set of files in Get Info, then getting iTunes to fetch artwork which will then be set as a reference file rather than being embedded.
I use an old iTunes so unless you are using an ancient iTunes it won't help for me to give you great details. To erase artwork I simply get info on a series of files and check the box next to the artwork box without adding any artwork and close. To do it for single file I Get Info, go to the artwork display tab and click delete. Here's a Windows reference for a newer iTunes (but the "old Get Info" reference is for early iTunes 12 and no longer works with newer):I cannot delete embedded album artwork in iTunes 12

How can I do to transfer all iTunes library from my Mac book Pro to Time capsule without to lost the alphabetic sequence of songs

How can I do to transfer all iTunes library from my Mac book Pro to Time capsule without to lost the alphabetic sequence of songs & artists? What is the correct way to transfer my 3000 songs to Time capsule, to free the memory of my Mac? Thanks a lot. Carlo Molinari (Rome - Italy)

How can I do to transfer all iTunes library from my Mac book Pro to Time capsule without to lost the alphabetic sequence of songs & artists? What is the correct way to transfer my 3000 songs to Time capsule, to free the memory of my Mac?
The following are the basic steps to transfer your iTunes Media folder from your MacBook Pro to the Time Capsule (TC). Note: You will leave the iTunes Library, and its associated files, on the MacBook Pro as you will only be moving the media files.
Be sure to shutdown iTunes before starting.
Next, move the "iTunes Music" folder, located in ~/Music/iTunes/, to wherever you want on your TC's internal hard drive. Remember to leave the Album Artwork folder, as well as the three individual library files where they are on the MacBook Pro.
Wait a while. If you have a large library, this will take a bit of time.
Once the iTunes Media folder has been transferred, open iTunes. Note: It will still be looking at your local iTunes Library on the MBP. As such it will think that the iTunes Media folder is still on the MBP as well. However, we just relocated it to the TC. If you attempt to select any song, you will get an error that the song is "missing." Not to worry, we will correct this in the next step.
We need to tell iTunes the media has moved to the TC's internal HDD. To change where iTunes "looks" for the media, open iTunes and go to the Advanced > General tab and use the "Change..." button to tell it where your new "iTunes Music" library is located.
Once this is done iTunes will likely pop up a progress window telling you that it's re-analyzing your library. Let it complete this step.
As a final check to make sure everything when as planned, click on any library file from within iTunes and press cmd + i (or View > Get Info). At the bottom of the Summary tab in that window is a "Where:" section that tells you the actual file path to that piece of media; be sure that path begins with the name of your TC's drive, and not "Macintosh HD."

HT1751 if i back up my itunes library to an external hard drive and then add subsequent music and want to back that up a few days later, can i backup the only newly added music without backing up the entire library again?

hello,
if i back up my itunes library to an external hard drive and then add subsequent music and want to back up the newly added music a few days later, can i do it without backing up the entire library again? or do i need to back up the entire library each and every time i back up to the external hard drive?

Just copy Users/yourusername/Music/iTunes (containing your library-files) to your external drive as well as that (extaernal) folder that contains all your audio-tracks.

How can I open an AEP project and make all media OFFLINE?

Hi There,
I am working with an AEP file that is on the network that has pretty heavy media files linked to the project. Every time I open the file over the network, AE takes FOREVER to open it. I remember somebody showed me a way to open up a file and making all the media offline. Something like holding ALT when pressing the open button on the Open File dialog. Although, I can't remember if this is right. I'm on a Mac, and I'd like to know if there is a way to do this so I can open up the project without waiting, and simply link the files that I really need to be linked so I can work quicker.
Anybody have any suggestion? Thank you for your time and help!

>You can just change the name of the folder where your sources are stored.
That works well for Windows, but Mac OS is a little trickier. The OS keeps track of folder name changes (even on network directories) and will re-direct requests appropriately. Very cool for users, very bad if you're trying to fool a program like AE. (Had to struggle with this about a month ago to offline some files.)
The only way I was able to make it work was by changing the name of the folder from a different computer while the main computer was disconnected from that server.

How can I open my existing AppleWorks and ClarisDraw drawings?

I purchased iWork and installed it. Now AppleWorks is gone. I don't remember agreeing to loose AppleWorks when I installed iWork. I can't open my drawings.
Anyway, if AppleWorks is not going to continue, does anyone know what current/supported/ongoing application can import or open ClarisDraw and/or AppleWorks drawings? I really don't want to throw out my existing drawings and start over from scratch. I have some that I have brought forward from MacDraw to MacDrawPro to Claris Draw, and with some difficulty, to AppleWorksDraw.
By the way, if you wanted a program that worked a lot like ClarisDraw/AppleWorks drawing application, and you were starting fresh, which easy-to-use, intuitive, simple, not expensive, drawing application would you use?
Thanks.

Hi D,
Welcome to Apple Discussions and the AppleWorks forum.
As Roger has already noted, SHOUTING is frowned upon here. Please lose the capitals. A second item of forum courtesy: Since your question has little connection with the topic of this thread (opening Drawing documents), it should be posted as a New Topic. Doing so makes your question and replies to it easier to search for anyone coming later with a similar question.
Regarding Bento:
From what I've read so far, Bento can import only CSV text files. To convert an AppleWorks DB to CSV is a two step process, and one or both steps will require AppleWorks.
Step 1: Open the DB file (requires Appleworks 6), Choose List or a laytout that contains all fields, Save as...ASCII Text. This creates a tab delimited text file.
Step 2: Open the text file into an AppleWorks Word Processor document (or into any other WP or Text Processing application that supports Find/Change), use Find/Change to Find all the tab characters (\t) and Change them to commas (,). Save the result as ASCII Text. In the Finder, remove any suffixes from the filename and replace them with ".csv".
The .csv file should be importable into Bento.
Regards,
Barry

HT2534 How can I open new iTunes account and split my content

I have account on iTunes I start with my email for my daughter when we got her a new iPod know I have a iPad for myself using same account want to get new one for her and let have her music off my account

You can create a new account (e.g. via this page), but you can't currently copy or transfer content from one account to another - so anything that was bought or downloaded via your account will remain tied to your account

How can I update my iphone 4 and sync on itunes? All I get is :Could not back up the iphone because the back up is corrupt or not compatible with the iphone. -

Trying to update my iphone to v.5.1.1 however it downloads the version but just at the end of updating my phone I get the message: iTunes could not back up the iphone as the back up was corrupt or not compatible.
How can I fix this?
Thanks

The backup and restore from the iCloud was a little unnerving since the restore erased all information from the iPod. The iCloud backup and restore took a long time, but worked. I was very grateful.
Trying again to backup to iTunes locally proved to be the same challenging problem. The same backup to corrupt file was the message. The status bar showing backup seemed to move faster to start, but then slowed to a creep toward the end before the error.
When trying to restore a backup in iTunes, the "Restore" button is grayed out since it is looking for a local copy. Any restore would need to be from the iCloud which already worked but isn't the final solution.
Your suggestions were good, I am just in the same boat. Any thoughts about doing the following?
1) creating a cloud backup
2) resetting the iPod to factory defaults
3) removing all traces of iTunes from my computer and
4) installing iTunes and setting up iPod from scratch.
This is the next thing on my list.

How can I get songs (from CDs) on my Nano onto my laptop? Do I have to rip all the CD's again just becasue I'm using a different computer?

How can I get all my songs (from CDs) onto my laptop from my Nano?
Do I have to rip all those CDs again even though they are on the Nano?
I thought I was allowed to have multiple PCs and use the sync feature. Yet when I plug in the Nano the message says it will sync to what's on my laptop which are only a few songs I've purchased!!
I thought Apple was better than that?! And to think I was going to purchase an iPad! But if I can't synch my music to other devices, why bother.
In order to get my music to iCloud via iMatch, I guess I have to rip them all again! What a pain in the butt...:(

Just subscribed to InDesign CSS - problem: how can I open old Pagemaker 5 and 6 Files?

Files are not being recognized. Have read there might be a download of past PM apps available. Any confirmations?

Furthermore, consider this as your last wake up call!!!!
Pagemaker development and support was discontinued at least a decade ago.
At this point you should go through and convert any PageMaker content you think you will ever need to access since at some point, even InDesign 8 (CS6) won't run on future operating systems versions.

I need to open encrypted word documents at my work to edit reports which are sensitive in nature, then be able to send them back to colleagues encrypted. I would like to do this all on my iPad. Are there specific apps I can download to be able to do this? Right now I'm using Google Drive for documents online and would like to be able to utilize this.

You can download these free MS Office apps (Word, Excel, PowerPoint) to view (but not create or edit) these files.

How Can I go Back to Leopad and sill keep all my data, e-mails etc.

Hi
I installed SL on Sept 3,2009. I'm a new Mac user so all I had was TM Backups which I still have. After SL install I have had lots of problems and a couple of days ago My system already failed and would not start. Called Apple, they said I had to re-install my OS. If that was the case I said I wanted to go back to Leopard, I was told use the leopard install disk and use disk utilities to locate the last Leopard TM backup and restore from that point and from there I was told I could recover all my Data, e-mails from Sept 3, 2009 the point of recovery at the time Sept 15/2009.
When I called back in after recoving to Sept 3/2009 for help in my data etc to Sept 15/2009 I was told I had been given bad advise, and that was not possible. So I have had to re-install SL and get back my data and e-mails etc to today. You can imagine how frustrating all this has been.
I'm now back on SL with all my Data, emails, etc but still experiencing many problems, and what I'm reading on this site makes me nervous that the worst is yet to come. My Tm seems to have double the amount of stuff and is a mixture of Leopard and SL backups. Is there a way of now going back to Leopard and then retrieving all my Data, form TM or from the other stuff I have saved? I have made copies of Mail, itunes, Documents, Safari, and I have all my pictures on my PC I have not added any since converting from my PC in early July. If I knew where they were I'd make a copy of them as well. I know there are a lot of smart Mac users out there so I'm hoping someone knows of a way of doing this, and can explain it it easy steps of a novice user. If there is someone from Apple out there reading this given the problems with SL I have had, and the bad advice on how to recover, some accurate, detailed instructions on how if possible I can get back to Leopard with all my data, it would sure be nice to hear from you.....

I rolled back a system from OS X 10.6.0 to OS X 10.5.8 via the Archive & Install (non-preserve) and it was successful. Now it didn't have any 3rd party applications installed. It just had the default OS bundled applications, iLife '09 and iWork '09. So that could have assisted in my success, I'm unsure how successful the process would have been if there was a lot of 3rd party framework modification. Although most of that would have been wiped clean in the Archive & Install, thus negating the problem.
Personally, I'd be more inclined to have you copy the contents of your Home folder (minus the Library) onto an external HD and manually reimport after a clean install of Leopard. The problem with that, however, is you'll lose Safari bookmarks, iCal data and Address Book data. So for something like you'd need to manually dig through the appropriate Library folders.
Are you near a Genius Bar? It might be worth visiting them and asking them for some assistance. I know when I worked there I was always outwardly accommodating when the issue was caused by inappropriate information that led you in the wrong direction from the start.

How can I connect my iphone 4 and my mac mini, running mountain lion, so that I can airplay music to my mac mini from my iPhone? Or, is this not possible?

Just trying to stream music from my iphone to my mac mini speakers. Any way I can do that in a similar way that I can do it via applte tv?

No.
Since all music on your iPhone should be in your iTunes library on the Mini if that is the Mac you sync your iPhone with, play the music from iTunes on your Mini through the Mini speakers. If the music is in your iTunes library on another Mac, set up Home sharing to play the music in your iTunes library on another Mac with iTunes on your Mini.
