Please PSD > 2 GB limit and faster save algorithms

The title of this could also be: Please stop adding gimmicks and improve first performance of existing permanently used functions.

When will we get PSD files > 2 GB and faster save algorithms?

I have a fast SSD as buffer disk, connected by USB3.1, working on iMac with fast internal SSD (1 TB), 16 GB RAM and 4 GB VRAM. So no performance issue caused by hardware.

Nevertheless, saving is slower as a snail goes and is wasting huge amounts of time.

Specially in those cases, after 2 Minutes or more waiting for file save to be finished, Ps pops up with the message "File to big, must be saved as PSB".

Sorry guys, but this is super annoying.

1. Ps could do this automatically itself. Why is does not? I can not make an unattended file save. Dmnd.

2. File saving always saves all of the file instead of only the changes. Buy a copy of Affinity Photo and check how fast .afphoto files are saved.

3. Why Adobe can not implement point 2.????

Photoshop has a lot of features and gimmicks, this is super and I like it. But I only need it on 0.5% of my work.

Before adding more and more gimmicks no one needs or only once a year, please enhance the all day 99.5% used functions like faster file saving, getting rid of 2 GB limit and PLEASE for the one millionth time: add a PREVIEW to Radial/Zoom Blur filter................!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Asking for this since 2005. And I know for sure, I am definitely not alone with this request.

What takes time is the compression to save disk space. You can turn that off in Preferences.

With compression disabled, most files that took minutes will save almost instantly. Try it for yourself, you'll be surprised.

Yes, the 2GB limit is a bit annoying. But remember the psd specification was made when 2GB files were science fiction. Just get in the habit of using PSB when you know the file is big.

BTW - you'll notice missing thumbnails and metadata in Bridge for PSBs. This is because the default setting for "Do not process files larger than..." is 1 or 2 GB (can't recall). You can set this to whatever you want, I have mine at 10GB just to get it out of the way.

Here's the reason PSD can't be programmed to exceed 2 GB as explained by Chris Cox (who was the senior engineer on Ps for 20 years).

"PSD limits pixel dimensions to 30,000 x 30,000 and max size to 2GB.

PSD files are limited to 2 Gig because of the file format design and compatibility with other applications. That really cannot be changed.

That's why the PSB format was created, to allow for much larger files (in pixel dimension and total file size).

300,000 x 300,000 and 4 exabytes, which modern hardware does not touch.

PSB files work up to around 4 Exabytes, and we can't go beyond that without changing the OS file APIs to allow more then 64 bits for the file size and position."

I believe there is a good reason for this. Photoshop uses a strict "safe save"-procedure. This means the file sitting in RAM is written in its entirety to a temp folder, then file integrity is checked, and only after that is the original replaced with the newly saved version - and finally the temp version deleted.

Partial/incremental saves seems more risky.

I believe how it is done may depend one the file system being used it would be relative easy for a file system to write the new file data on the same disk as the old existing file in the disk free space and when the file data is complete on disk updated the files directory entry with a single directory write th old file data sectors are returned to disk free and the file data replaced with the data sectors written for the updated file content.

Thanks for the hints, I never tried it before. Oh yes, that accelerates file saving. But - OMG - it doubles the files size.

On comparable projects (same megapixels, same effort necessary like spots, pimples, frequency separation, yeah, you know what I mean, business as usual...), Affinity Photo compresses also, probably ½ to ⅔ of compressed Psd size, but for sure 5 to 10 times faster as Ps compression activated.

This is first time saving. - If you apply then any further changes and press Cmd+S, AP file saving takes only seconds or on tiny changes only fractions of a second.

A frequency separation in Ps like in AP, still dreaming of it

Are you processing the same layer psd File in Affinity. There are many data compression algorithm Some are faster the others but don't compress as well as others. You make trade off . Some of Photoshop Image file type save options have support for different compression methods. You have many compression options saving Tiff file which can save your layers and tiff file size limit is twice that of PSD 4GB. Perhaps you should try Tiff File compression has two compression options for compressing layers.. Make the trade off the works best for you.

A frequency separation in Ps may be coming. The preview the Trevor posted a while back looked like FS to me but the date look like 2015???

So you think Photoshop is a File editor. Photoshop is not a file editor. You also think when a file is updated it is updated in plade. and only sections of a file may need to be replaced. File systems do not work the way.

It may not be the writing the file data to your SSD that is consuming time. What is consuming the time is packaging up the file data. If you need to save as PSB it is because you file data is over 2GB and if you have not disable compression on PSD and PSB file your data could be many times that 2GB number. If you have not disabled Compression and all you files are being written to ssd. Perhaps disabling compression will actually speed things up. Your SSD may fill up faster also. Try disabling compression in your Photoshop preferences if you have not done so.

This is a user to user forum. If you have ideas for improvements use the official form. Feature Request/Bug Report Form

Thanks for the hint and sorry for posting in the false place. But the forum system is totally weird and distracting - at least to me. May be I am stupid or so.

Please let me show up the only way to enter something in the Adobe forums as they present themselves to customers - in a logical manner, without wasting hours until finding accidentally the correct entry point of place to post, I do this:

1. Go to forum.

2. Search if a similar question already exists (to my, never yet).

3. Open a new discussion

4. Select Photoshop

5. Type your concern

6. Click send button.

I had no clue yet, the feature request/bug report forum exists. Probably I once tried it but I am pretty sure it brought me back top starting point 1. Sorry, but user convenience is no strength of Adobe and for sure not of the forum. Please take this as constructive critics (as we say literally in German), and use it as change to enhance support quality and user experience.
