Running Photoshop On A Pc Computer,....you Might Find This Interesting.

I posted this on an older and maybe now unread thread last evening,....so I am posting it once again should anyone find it interesting.
******************************************************************************************************************************************************************

For what it's worth,....One of my primary solutions to ......Reclaim Valuable PC disk space that can slow your PC.

This practice I use almost daily,....I learned this years ago and perform this practice every single time I use photoshop.

I have no particular qualifications other than I have been a photo editor for almost 10 years using photoshop on my PC computers editing hundreds of images for a magazine going into its 26th year of publication.

This post refers to reclaiming rather large of amounts of residual disk space,.....on a PC computer running photoshop.
Here's what I've learned and am throwing it out there for anyone who might like to explore for themselves.

When you use photoshop on a PC,....it creates many, many hidden cache files that accumulate extremely quickly,...these files really add up fast and eat up valuable amounts of disk space.

Humor me for a moment,.....do the following search on your PC computer that runs photoshop,.....

Search your PC computer directory structure for the term> cache*.dat

What you are looking for are fiiles beginning with with the word (cache) followed by 10 arbitrary numerical values followed by the extension .dat

example,......> cache0000012345.dat ONLY these cachexxxxxxxxxx.dat files are applicable,....Other files ending in a .dat extension are not to be touched.

If I am correct,.....your search return an extensive number of these (cachexxxxxxxxxx.dat) files,....possibly in the thousands of these cachexxxxxxxxxx.dat files.


Next,....highlight (select) all these cachexxxxxxxxxx.dat files,.....right click and select Properties,......you will now see the size in MBs or GBs of ALL these cachexxxxxxxxxx.dat files your search just located ,...these represent wasted disk space,......the numbers should astound you.
This used space can exceed up to many, many GBs,....all clogging up and slowing down PC performance,...always growing in size every time you use photoshop on your PC.

ALL These (cachexxxxxxxxxx.dat) files can be safely deleted from your computer,....they are residual cache files, left behind by photoshop,...they have been accumulating for as long as you have been using photoshop on your PC.

Photoshop is placing these files at a directory location designated by your prefference > cache settings in Bridge. Edit > Preferences> cache

In my computer I have a designated extended partition H; that I created and that's where I elected all my (cachexxxxxxxxxx.dat) files are placed,.........

If you havent designated a "cache" location under Bridges preferences> cache,......photoshop could be placing ....ALL THESE..(cachexxxxxxxxxx.dat) files,....into your C; operating system directory,....thusly slowing down your operating systems valuable resources and operating system hard drive space.

Everything I am describing is for a PC computer ONLY,...I have no knowledge how a MAC computer handles everything.

I use this space saving solution on 2 Windows 7, 64bit operating system computers,......as well as on a Windows XP computer operating system.

For those more versed than I on computers,...I am sure there are ways to verify the methods I am describing here.

The first time you do a harmless search for (cache*.dat) files,......should be quite revealing.

I can only attest to the above by my own practices,......I perform this each and every time I use photoshop on my PC computer.

You should be familiar with the PC directory structure or delving into searches and tampering with files as mentioned here.

I hope my lengthy description might be beneficial in some small way.

I am basically a self taught computer user since 1991, I built my first computer from scratch several years ago,.....I am responsible for several PC computers running photoshop and employ these techniques regularly.

By the way my versions of Photoshop I constantly use are CS6 (not the CC version) and CS5.

To give you an example,...I have been editing images in CS6 for the past 3 days,.....maybe 4 or 5 images max,....preparing to post on FAA.
I just performed my cache*.dat search,....and I have 1,654 hidden cache files accounting for 577MBs of wasted space from those files on my H: partition,......which I have just deleted.

Thanks for any interest and I hope any reclaiming of readers hard disk space via my practice results in a leaner and faster operating system.

I searched and found 0 files under cache*.dat on my 1 TB hard drive nor on more than 20 TB of back up drives.

This may be because I regularly run Glary Utilities and clean unwanted files.

I don't run any utility to remove files, unless you count norton360 and a spyware program. I had no files of this description.

I DID find some photoshop or other scripts that refer to cache. My supposition would be that you've run some plug-ins that were poorly written, and leave little disk-turds on your hard drive. I suggest you check for this trash after using various plug-ins and attempt to determine the offender in that manner.

Cool. I found 2,254 files taking up .99 GB of my precious C drive space. I have a SSD C drive so it is not huge - fast but not big.

I do have a question though. Those files said they were from Camera Raw but when I checked my preferences in Bridge it said my Cache files are bridge thumbnails and previews and are located in a folder with bridge in the location string.

I don't know how many files were in that Bridge cache but when I cleared it I gained 38 GB of free space on my C drive. Of course now when I go to Bridge it will have to redraw whatever thumbnails and previews I want to look at so will take longer but 38 GB freed up - WOW.

Thanks for inspiring me to take a look.

At first the search said I had 0 files but then I had it search the computer it it found the 2,254 files. I really hate the search feature in Win 7.

Hi John,

Will take a look at Glary Utilities.

Are you using the free or paid Pro version?

I'm just so accustomed to how I've omitted the cache files via a search/delete method.

Someone also suggested writing a batch file to automatically remove the cache files.

Always enjoy the technology

Your portfolio is beautiful John, very nice work.
Congratulations on your fine accomplishments and successful image sales and showings.

Thank you for the info and nice meeting you here in the FAA discussion group.

Marty - I use the Pro version - under $12 a year.

Thank you for the kind words!

Hi Mary Jo

Those files show up in a ACR Cache folder on my H; directory.

Any redraw of cache thumbnails goes rather quickly on SSD drives anyway.

Windows 7 windows explorer search window (Search Libraries) at the upper right corner,...will retain the search term (cache*.dat),....so that it's readily available whenever you opt to use it for a search.

Am glad you found and reclaimed so much space,...especially on your primary C; operating system directory,...that is good.
Less clutter is always better.

I always say,........We all do the same things,...... different.........no matter what the subject........much truth there.

Am enjoying and always learning here.

Nice meeting you here in the FAA discussion group Mary Jo.

Marty.

Yeah, those cache files are thumbnail images. You can erase them, but they will be redrawn every time you open Bridge, which takes a lot of time if you have a lot of files. If space is at that much of a premium, a better suggestion would be to move all unnecessary files to an external HD and only keep the ones you need readily at hand on your computer. That will free up a lot more space than just the thumbnails.
