Setting File Handling Preferences

How you handle your images after importing them into Photoshop is almost as

important as creating the images themselves. In this set of preferences, you

can specify how you want Photoshop to manage image previews, file extensions,

and workgroup functionality. You can also set file compatibility and the number

of files that should be displayed in the list of recent files on the File menu.

1. If you are a Macintosh user, go to the Photoshop menu and select

Preferences ➪ File Handling (see Figure 1-1). If you are a Windows

user, choose Edit ➪ Preferences and select File Handling.

box on Mac OS

2. In the File Preferences dialog box, as seen in Figure 1-2, the first set

of preferences under File Saving Options concerns image previews.

Image previews are small snapshots of the overall image. These

images are referred to as thumbnails and allow for easier manage￾ment of your files. You can set the image preview preference to

Always Save, Never Save, and Ask When Saving.

3. The Macintosh version of Photoshop CS also enables you to select

Icon, Full Size, Macintosh, and Windows Thumbnails. Select the

Icon checkbox and the program displays the thumbnail as its file icon

on the desktop. If you check Full Size, then the program saves a 72

points per inch (ppi) version of the file for use in other software

applications that support low-resolution Photoshop images for

quicker workflow. If you select Macintosh Thumbnail, you get a pre￾view of the image in an Open dialog box; likewise the Windows

Thumbnail option saves a preview for Windows operating systems.

4. The set of preferences under File Saving Options controls whether

the program appends file extensions when saving files. A file exten￾sion consists of three (or four) letters preceded by a period at the end

of a file name. While not needed for Macintosh operating systems,

file extensions help Windows systems determine what kind of appli￾cation is needed to open the file.

notes

• A file saved as TIFF can be

larger than 30,000 by

30,000 pixels but is lim￾ited to a 4GB file size. The

Large Document Format

has no file size limit.

• The options for maximizing

compatibility and adding

image previews with the

image file increase the

overall file size compared

to not leaving them on.

Be sure to determine what

features you need if file

size becomes a concern.

tip

• While Macintosh systems

don’t require a file exten￾sion to handle files, in

order to exchange files

between Macintosh and

Windows operating sys￾tems you will need to

append the file extension

to the file name.

5. If you want Photoshop to ignore the EXIF sRGB tag when you

import images from your digital camera, select the Ignore EXIF

sRGB Tag checkbox under File Compatibility. The EXIF file provides

information that comes from your digital camera and helps programs

like Photoshop determine the color space for the digital photos.

6. To be reminded about saving a TIFF file with layers, check Ask

Before Saving Layered TIFF Files under File Compability. In order

to share TIFF files with clients or colleagues working on different

platforms, who might not have Photoshop, you would want to make

sure not to send a TIFF file with layers.

7. If you work with large digital images, you might want to select the

Enable Large Document Format checkbox. The Photoshop file for￾mat (.psd) is constrained to 30,000 by 30,000 pixels, wheres as the

Large Document Format (with the extension .psb) supports images

larger than 30,000 pixels.

8. To ensure greater backwards compatibility for your files with older

versions of Photoshop, check Always Maxmize Compatibility for

Photoshop (PSD) Files.

9. To turn on workgroup functionality, select Enable Version Cue

Workgroup File Management.

10. The bottom part of the File Handling preferences dialog box enables

you to specify how many files are listed in the file menu when you

select File ➪ Open Recent.
