Question

How to change installation's partition

Hello everybody,  I have a question for a specific issue:

- I installed PS, LRc, Bridge etc. on my PC Windows

- everything is working fine, no problem at all

- but free spece on my C drive is almost full, because (I do not remember why ...) I installed Adobe applications on drive C, where is working operating system too

- I have a second partition D which has a lot of free space, so I would move all adobe applications I have from C to D

Questions:

1) how can I do that? I think I should delete everyting from disk C and reinstall everything on drive D, correct?

2) if I do that, what is the starting page from which I reinstall everything? (in this case I will set the installation drive to D since the beginning when executing the procedure

Thanks a lot for support, best regarsd, Pierpaolo

This is actually quite pointless.

 

All your applications have components, separate from the program files, that need to be under your Windows user account, and that has to be on the system drive (C) regardless of where the application is installed. 

 

I just took a quick look at my own machine, and Adobe files in my Windows user account - not the program files! - weigh in at almost 30 GB total. Now, over 20 of that is the Bridge cache, which I have chosen to keep on C for performance reasons. But it can be moved, and if you move this to D, that alone will free up more space than if you install everything on D. The Photoshop scratch disk can also be put on D. This is only active when Photoshop runs, but can run into hundreds of GB under heavy load.

 

Photoshop by itself takes up about 3 GB in my user account. That's still more than the installed program files.

 

It's a little late now, but partitioning is actually not recommended for solid state drives. It doesn't do anything for efficiency or speed. The only advantage is for organizing so that you can separate system from documents, but it would be better and safer to have separate drives.

    Dear Fosse and Axel, I checked the page of Creative Cloud looking for strange things or messages, after having clared the cache with no significant results and I saw that I had three different version of PS (24+25+26) available from Creative Cloud and three of Bridge too (13+14+15). So I wandered: "why?". My fault probably ... So I uninstalled 2 versions of PS and 2 versions of Br, getting back 10,1 Gb of free space on disk C (I did not do anything on drive D). This should fix the warning and error messages about lack of disk space. Keep you posted here if the problem is still open ... Hope the community take benefit from this problem and solution.

    thanks, Pierpaolo

    This is a normal behavior. On every installation of a main update 24 to 25, 25 to 26 and so on you'll been ask if you will kept the previous version. This can be useful if you have a important project that has to be finished on the old version. Or you will test the new version.

    If you've finished the project or you happy with the new version you should deinstall the former version.

    Yes, you have to do a complete reinstallation.

    See here: Change install location of your Creative Cloud apps
