what are these files?  NTUSER.DAT and .regtrans-ms

Really lost here.  Don't know what these files are.  Not sure if they are causing problems or if I can delete them.

These wierd files show up in my user accounts.  Some of them are long file names - which I believe is causing problems with Adobe Dreamweaver CS3 (giving me a "your system is low on memory error").  I've also had other problems like Adobe Bridge not working and every once in a while a complete blue screen.

Can anyone tell me what these long file names are all about?  NOTE - I've changed some of the numbers in case it refers to something to do with security.

Wish I could post an image of all these files.  There are about 8 of them for both user accounts.

NTUSER.DAT{1a539871-1a70-11db-887c-d162bd253390}.TMContainer00000000000000000001.regtrans-ms

Not even sure what to ask .... but I'd like to get rid of these if they are spam or something.

Thanks, April

Hi April,

the NTUser.dat is the file that stores information about your profile (user account)

it stores your internet explorer book marks, desktop configuration settings and a whole range of othre data.  If you delete this, and are not on a network with stored profiles, you will definitely lose all of your configuration settings and may not even be able to log back into your account.

the regtrans files are linked to your NTuser.dat file and I believe contain information pointing to youor registry. I wouldn't advise deleting any of them but instead would suggest that you hide them by changing the view on your folders to hide protected operating system files

Sorry, for the second part of your question regarding adobe, i need to know how much memory you have installed, how much of that is free and what other programs you have open while trying to use the Adobe programs.

I would say that you need at least 256 MBS of RAM to even think about successfully running CS3 on your machine.  If you have enough memory (preferably 512 Mbs0 I would suggest uninstalling the program and doing a clean re-install and then going to adobe's website and installing all of their updates.

your problems are very generic and nature and a re-install will often solve issues like these

Thanks for the answer ... perhaps I might have solved the problem by deleting all my IE browser files.  I'm suspecting I had a Favorites link that had a path name that was too long -- which was causing Dreamweaver CS3 to respond with the "low resources" warning.

I'm sorry my question wasn't explained more thoroughly --- but I actually had to do some work today - rather than spend more days trying to fix problems with Adobe CS3.   I'm a web developer.  I've had so much trouble this year with Adobe CS3 and Vista and Toshiba -- that I bet I've spent as MUCH time trying to fix software problems as I have actually developing web sites.  

I've installed and re-installed Adobe CS3 at least 20 times this year.  

I have a Toshiba Qosmio Laptop  that I purchased about a year ago for over $3,000.

I'm closing this question because the first answer let me know what the NTUser.dat files were for.  

Hopefully, the other problems are now fixed.

Thanks so muich to Chokdii - for the quick response and the extra care in  addressing both my questions.

Thanks, April

For clarity - I accepted first answer because Expert explained what NTUser.dat are for ... and lead me to suspect my Favorites were causing the problem.

Many thanks to the Expert for quick response and extra effort in addressing the other questions.

Thaks, April
