Your file handling preferences determine how Photoshop reads, writes, and backs up your data. Optimizing these settings is crucial for preventing crashes, reducing the time it takes to save large files, and managing your hard drive storage.
Image previews generate a small thumbnail version of your file. They are useful when browsing through visual folders in Mac Finder or Windows Explorer, but generating this thumbnail forces Photoshop to process extra data and unnecessarily increases your overall PSD file size. The dropdown gives you three options: Never Save, Always Save, or Ask When Saving. If you properly name your files and don’t rely on thumbnail previews, change this to Never Save.

When checked, Photoshop will process saving commands in the background. This allows you to continue editing your document or switch to another tab while a massive file writes to your hard drive. You should absolutely keep this enabled.

If you are dealing with Photoshop lagging or crashing, this setting is your lifeline. It creates a temporary backup of your file at the specified interval. The dropdown options are 5 Minutes, 10 Minutes, 15 Minutes, 30 Minutes, and 1 Hour.
10 Minutes is generally the best balance. Setting it to 5 minutes can cause a spike in system resource usage while working with huge files because Photoshop is constantly stopping to save in the background. Conversely, 30 minutes or 1 hour risks losing too much progress during a crash.

When you save a layered document, Photoshop naturally compresses the data to save storage space on your hard drive. However, compressing large files requires CPU processing power, which takes time. If you have plenty of free terabytes on your hard drive and you want your massive PSB files to save instantly, check this box to turn off compression. Beware: if you enable this option, saving files will be much faster, but the files will take up significantly more space on your disk. If you have limited disk space, leave it unchecked.

What is the purpose of the maximize PSD and PSB file compatibility setting? It saves a flattened, composite version of your image alongside the layered data. This makes it easier to open your files in older, legacy versions of Photoshop or third-party applications (like Lightroom or After Effects). However, it adds a massive amount of bloat to your file size.
The dropdown gives you three choices: Always, Never, and Ask.

When you choose File > Open Recent or look at your Home Screen, you will see your recent documents. You can change this to show the last 5 or up to 100 documents you’ve previously worked on. You don’t need to restart Photoshop for this one; it will immediately update your recent files list.
