A folio includes one or more digital publishing articles. A folio appears as an issue in the library of either the Adobe Content Viewer or a custom multi-issue viewer. If you create a custom single-issue viewer, the folio includes the contents of that viewer app.
Use the Folio Builder panel to create folios and add articles. To open the panel, choose Window > Folio Builder (InDesign CS6) or Window > Extension > Folio Builder (InDesign CS5 or CS5.5). The Folio Builder panel displays the folios to which you have access. The Folio Builder panel includes three views: folio view, article view, and layout view. To navigate, do any of the following actions:
Double-click a folio or click the arrow to the right of the folio to display the folio’s articles.
Double-click an article or click the arrow to the right of the article to display the article’s layouts.
Click the arrow icon in the upper left corner of the panel to move up a level.

To determine which folios are displayed, choose All, All Local, In the Cloud (to hide local folios), Private (to hide shared folios), or Shared from the drop-down menu in Folio view.
Choose an option from the Sort drop-down menu in Folio view to determine the sort order of folios in the Folio Builder panel. Select Reverse List to reverse the order for any folio selected.
Signing in to the Folio Builder panel is optional. Signing in to the panel lets you upload folios to the acrobat.com site. You can then download folios to the Adobe Content Viewer on a mobile device and share folios with other users. If you don’t sign in to the panel, you can still create and preview local folios, and you can build a Single Edition app. Use a verified Adobe ID to sign in to the Folio Builder panel.
If you have an Enterprise or Professional subscription to DPS, use the Account Administration tool to create an Adobe ID with an Application role. Use the appropriate Adobe ID to sign in to the Folio Builder panel. See Account Administration tool.
To verify an Adobe ID to work with DPS, go to https://digitalpublishing.acrobat.com/ and click Create Account. Sign up for an account using a valid email address. Adobe will send you a verification message. Open that message and verify it. Then use that Adobe ID to sign in to the Folio Builder panel. See Using Adobe IDs for digital publishing.
A folio is a collection of articles. Anyone with InDesign CS5 or later can create folios.
When you sign in and create a folio, a workspace is created on the acrobat.com web server. The content of any article you add to the folio is uploaded to that workspace.
Creating a new folio.Folio Name
Specify the folio name. The folio name is different from the Publication Name that appears in the viewer. The folio name is used only internally, so keep the name simple and avoid using extended characters. The maximum number of characters for Folio Name is 60.
Viewer Version
Specify the target viewer version. This option is especially useful if either the newest version of the Adobe Content Viewer is awaiting approval or if you’re creating folios for an earlier viewer app that has not yet been updated. Once you create a folio, you can edit folio properties to increase the version number, but you cannot roll back to an earlier version. Instead, create a new folio. You cannot specify a viewer version earlier than v20.
Target Device
Select the target device or specify custom dimensions of the target device, such as 2048x1536 for an HD iPad.
When you specify the folio size for the target device, take into account whether the device displays a navigation bar. For example, a 48- or 75-pixel navigation bar appears in some Android devices, causing the viewer to scale a 1280x800 folio. Instead, create a smaller folio size (such as 1205x725) for dual-orientation folios. See Creating documents for multiple devices.
Orientation
Indicate whether the folio is portrait-only, landscape-only, or dual orientation. To preview or publish the folio, all articles must match the folio orientation. For example, if a dual-orientation folio includes an article with only a portrait layout, the folio cannot be downloaded in the Adobe Content Viewer library.
Default Format
Choose a default option for the folio. Individual articles can have different Article Format settings.
Choose Automatic if you want to let InDesign determine whether to export the pages as JPEG or PNG. Choosing PDF lets users pinch to zoom in and out, preserves vectors, and reduces file size. Specifying the default format is especially important for importing multiple articles. Articles in a multi-article import use the default image format. See Differences Between JPG, PNG, and PDF Image Formats.
Default JPEG Quality
If Automatic or JPEG is selected for Default Image Format, specify the JPEG Quality. Increased quality increases the file size.
For information about troubleshooting the Folio Builder, see Troubleshoot Folio Builder and Troubleshoot article upload failures in Folio Builder panel .
After you create a folio, you can use the Folio Properties dialog box to specify a publication name, change the viewer version, and choose cover preview images. Some folio properties such as orientation, image format, and folio size cannot be edited in the Folio Properties dialog box. If necessary, create a new folio with the appropriate settings.
When you’re ready to publish your folio, use the Folio Producer Organizer to specify folio properties for publishing.
Publication Name
The Publication Name you specify appears in the viewer library. However, if you use the same Publication Name value for all the folios that appear in your app, the Publication Name is omitted from the library by design.
The maximum number of characters for Publication Name is 60.
Note:
To avoid problems, use only alphanumeric or numeric characters in the the Publication Name. Do not use special characters such as apostrophes (‘), or unexpected results such as an “[svr.InvalidParameter]” error message might occur.
Viewer Version
If you want to specify a different viewer version for the folio, select the appropriate version. You can select a newer version, but not an earlier version. To target an earlier version, create a new folio.
Updating the viewer version of a folio does not automatically update the articles in that folio. If you want to take advantage of a new feature that works in the higher viewer version, update the articles as well.
Note:
If you’re editing a folio that was created before v20, make sure that you specify a Viewer Version setting.
To change additional folio properties for publishing a folio, choose Folio Producer from the Folio Builder panel menu, and specify settings in the Folio Producer Organizer. See Folio Producer Organizer
Folio Name
The Folio Name appears in the Folio Producer and in the Folio Builder panel, but it does not appear in the viewer. If you are creating renditions for different devices, make sure that the Folio Name settings are the same among renditions.
Publication Name
The Publication Name appears in the viewer library and in the viewer navigation bar. However, if the same Publication Name is used for all folios in an app, the Publication Name is not displayed in the library by design.
The maximum number of characters for Publication Name is 60.
Folio Number
The Folio Number can be a number or a description, such as “May 2013.” The maximum number of characters for Folio Number is 60.
Publication Name and Folio Number appear in the viewer.Publication Date
The Publication Date setting determines the order of folios in the library. The newest folios appear at the top. The Publication Date setting is especially important for subscription viewers in which customers are entitled to folios within a specific duration as determined by the Publication Date settings. For best results, manually select a Publication Date setting.
Product ID
The Product ID specified when you published the folio is displayed. You cannot edit this field directly. The Product ID is especially important for retail folios. It ties the folio to the in-app purchase Product ID in the app store. The maximum number of characters for Product ID is 60.
Locked
Select this option to prevent anyone from uploading a new version of the article or changing article metadata. A locked icon appears next to the article in the Folio Builder panel of anyone who has access to the folio.
Library Filter
Type the filter name for each folio in your app. The maximum number of characters for Library Filter is 60. See Create library filters.
An offline folio, or local folio, is not uploaded to the acrobat.com service on the web. Creating an offline folio is especially useful when you’re not connected to the Internet, or if the acrobat.com service is temporarily out of service.
An icon indicates that a folio is offline.
Add articles and edit the folio.
You can preview offline folios on your desktop or using Preview on Device. See Preview folios and articles.
When you preview or upload an offline folio, the folio is updated automatically to account for changes to the source InDesign documents. Choosing Update to update an offline folio is not necessary.
Share a folio if you want to let other people review the folio you’re working on or to make it available to them. For example, if you’re creating an ad for a publisher, you can share the folio that contains your ad with the publisher. Or, if you’re a publisher, you can share a folio with different designers to let them upload articles.
Whenever you update an article in the shared folio, recipients are notified that an update is available when they open the library in the Adobe Content Viewer. If you don’t want recipients to view updates, unshare the folio.
When recipients open the Adobe Content Viewer on a mobile device, the shared folio is available for downloading.
If recipients open the folio in the Folio Builder panel, a share
icon 
appears next
to the folio name in the Folio Builder. Recipients can open the
folio and add articles. However, they cannot edit existing articles.
Unshare folios
To unshare a folio that you shared with others, select the folio in the Folio Builder panel, and choose Unshare from the panel menu. Select the recipients with whom you want to unshare, and click OK. Unsharing makes the folio unavailable for downloading and removes it from shared recipients’ Folio Builder panel, but it does not remove folios that have been downloaded to devices. Deleting a shared folio also makes it unavailable for downloading.
Remove a folio shared with you
If someone has shared a folio with you and you no longer want access to it, select the folio in the Folio Builder panel and click the trash icon. Deleting the shared folio removes your information from the owner’s shared recipients list.
When you delete a folio, you remove the workspace from the server, and you delete all articles in that folio, but not the source documents. If you published a folio to the Distribution Service, use the Folio Producer Organizer to unpublish that folio before deleting it. Avoid unpublishing and deleting retail folios.
