:w00t: :huh: As I recently attempted to backup my Windows directory (WinXP SP2) I received an error message indicating a path name was too long. On closer investigation I found a really strange file lurking in my Windows\System32\Drivers folder. The file is a .MRK and the file name is exceptionally long, in fact it's the longest file name I ever encountered. Opening the file's properties doesn't provide a lot of info besides the file being a MRK file and opens with an unkown application :hmm:
The file name is:

HP_DQ176A-ABA a430n_YC_Pavi_QMXM406_E41NAheBLU4_4_IA7N8X-LA_SASUSTeK Computer INC._VRev 1.xx_B3.07_T031015_WXH1_L409_M512_J160_7AMD_8Athlon XP 3200+_92.19_110DE006E_N10DE0066_P_Z11C1044C_K_A10DE006A_U10DE0067_G10DE0181_OHP DVD Writer 300c;ASUS CD-S480 AH_DHWP2594_HSAMSUNG SP1604N;Generic USB CF Reader USB Device;Generic USB MS Reader USB Device;Generic USB SD Reader USB Device;Generic USB SM Reader USB Device_F6.14.10.4528_.MRK

The file size is 4.03KB and it's contents are:

Can anyone tell me what the purpose of this file is and what is it doing in the System 32 Drivers folder?

I've moved the file from the system32 drivers folder to a temp folder on an external USB Drive and as yet I have found no adverse affects with any applications or hardware I have installed.

Appreciate your help on this one; in advance thanks! :rolleyes:

For a start, here's a choice:

Hello,

Judging from the file name and contents, I suspect the file was created during installation as a temporary file for troubleshooting purposes and not removed. The fact you were able to remove the file without altering the behavior of the system indicates its presence is not critical.

Hello again,

Claymore thanks for the link it provide a little more insight on MRK files, although I still don't quite understand what purpose a file with such a long file name could possibly serve.

Goretsky thanks too for your input. I too suspect the file was "created" during installation. It's properties indicated that it was created on 9 Mar 2004. That was nine months before I bought my PC! Also the file attributes indicate that it is read only and hidden.

Oddly enough, the file in question was not in my System32/Drivers folder before I installed the latest Windows XP patches this Tuesday. I checked previous Windows folder backups I made last month and this past Monday before patch Tuesday and the file is not there.

Still strange that this particular file should appear in the drivers folder if it wasn't there before or could it be that the latest Windows patches unhid the file eventhough my system was already set to show hidden system files?

Anyway, moving the file has not adversely affected my system as far as I can tell.

Again, thanks for your assistance.

Just from looking over the file name, I'd suspect that it has something to do with card readers on your system - and may be a leftover from the initial image that was used to create your hard drive.

You might want to check in Device Manager to see if this driver is assigned to any of the devices that are listed in it's name.

I agree that its doubtful removing it will hurt anything. In the intrest of your further knowledge I would drop a note to SASUSTeK Computer INC . They are mentioned in the name so maybe they know what its for. If your like me & just want to know things. Otherwise just dump it if its not changed anything since you moved it.

I found this
Quote:
A .mrk file is a file that contains the PDF bookmarking information separately. Technically, it is a text-based file in Adobe pdfmark compliant scripting language format. If this file is processed through the BMK Automatic Mode along with the relevant PDF (that requires bookmarks to be added), the end result is a bookmarked PDF document. This file gives us the ease to save our bookmarks from the PDF documents and to reuse it as and when desired.
It might be a file that your Pavilion uses when you open the HP help file? Not sure, just guessing here. Opemn some HP help files - about your computer and see if anything appears strange.

I'll have to fire up my HP Pavilion and see if I have .mrk files.

Found this thread on CastleCops, and there it looks as similar details as is contained in the file you find appears as the starting part of a HijackThis log. And the system involved is also a HP Pavilion.

I looked in my Pavilion8650C (98SE) purchased in 2000 and I don't have any .mrk files.
Then I fired up my nb, Pavilion N5470 (ME) purchased in 2001 and that also has no .mrk in the C:\Windows\System32\drivers folder. So my guess about it being needed for the HP help was completely wrong.

I've never had a HP system, but I've seen some of and noted that most of them were running quite a lot of different hp-specific programs and/or utilities. Among them, something I think had to do with automatic checks for updates to installed software/hardware.

Could one or other of those functions be creating such files while checking for relevant updates ?

:hmm: Short update on my .mrk file issue.

First a great big thank you to all of you who have given of your precious time to answer my post. All of your suggestions and insights were very useful to me. Once again all of you clearly demonstrated that helping others makes these Lockergnome forums so valuable. :thumbup:

Regretfully I've not been able to nail down the origins nor the purpose of the said .mrk (murk?) file.

As I regularly do, I updated and ran all of my security related apps (AVG Pro, ClamWin, SpySweeper, AdAware SE Pro, ASquared, Ewido, MS Antispyware, Spybot S&D) none showed any virus or malware contamination.
Ran three separate rootkit detection programs, all turned up negative.
Ran the latest HijackThis app with no unusual or unexplainable results.
Also checked all of my hardware devices and associated drivers and did not find any that were malfunctionning or out of date.
Checked my other PC, an HP laptop, and no .mrk files are on it eventhough it runs exactly the same apps as my desktop.

So I am still at a loss to explain the presence of said "murk" file and perhaps more importantly what program or set of conditions may have generated the thing.

As I stated in my initial post, I've removed the file from the drivers folder and have fortunately not suffered any ill effects. All my hardware and apps seem to get along just fine without it :tongue:

Nevertheless I would sure be interested in finding out how it got to my drivers folder in the first place and what the file's purpose is. :hmm:

Would hate to have to change my log on name to "Clueless" :w00t:

Again, thanks to all for your replies Smile

NO .mrk files here either. :hmm:

The one thing that you have to look out for when installing a new HP/Compaq computer these days, is Spyware.
They load it on at the factory along with tons of demo's and games.
It takes me over an hour to unload the C.R.A.P. from a new HP/Compaq before I can start installing software and setting up the internet, etc.
Getting rid of the Norton demo/trial is the worse!

Y'all have a great weekend now.

:thumbup: Morbius, really have to agree with you on that one new HP/Compaq are bloated with loads of useless apps. First thing to do with a new one is to make sure one does NOT connect to the internet. Second thing is to uninstall all those useless apps, demos, and other crap. Third is to install/run a decent registry cleaner, JV16 for example. Fourth is to install/run a decent AV prog and at least two, perhaps even three spyware progs such as AdAware, Spybot S&D, Webroot SpySweeper, MS Antispyware and the like. After rooting out the most prevalent spyware that is sure to be there one should then install a good IDS prog such as Spyware Blaster. Once one is certain that the new stripped down system is relatively clean of snoopware one should install a decent disk backup utility and perform a full system backup preferably to an external media such as DVD or external USB HD or better yet to both. With a full system backup of the "cleaned" and "stripped down" system in hand one can finally install one's own favorite apps and progs and even venture onto the internet.
Unlike driving a new car off the showroom floor, taking a new HP on the information superhighway without taking a lot of precautionary measures beforehand is a receipe for disaster :w00t:

A big whopping 10-4 to all the above.

On a new HP/Compaq computer I usually install (after manually removing all the crap files) the following:

AVG 7 FREE
AdAware SE/Personal
Spybot S&D
Spyware Blaster
MS Anti Spy
Trojan Hunter
Easy Cleaner
Reg Clean
XPCleanup.bat (my own concocktion)
MRU Blaster
and,,,,,a custom Hosts file

Then the PC is ready to go on the internet and get all relevant updates.

Anything less is just flirting with disaster.
It's a shame and a crime, that we have to protect ourselves from the very people who build our computers.
The one computer that I've seen that comes with the least amount of Crapware is "eMachine".
Pretty nice little computer with minimal crapware loaded.

Cheers,
Morbius Cool
