The Deets

You can choose to view the properties of the attachment to edit it. The screen is titled Mess with Your Stuff. If you open the properties of a version, the screen is titled Edit That One Version Thing and shows only the Name field.

What You Call This Thing

This is where you can peep & change the name of the attachment. This does NOT change the actual file name — we're not monsters.

Type

This field is normally blank but can be editable (fancy!). It allows you to enter in text that can be used to group like files together. For instance in the example provided, the value "76439-W.cc_2col_pdf" is a value that is the same on other 2 Column Layout files. This lets OnSong group these files together & switch between them based on key. Srsly, it's kinda genius if you think about it.

Key

This is normally blank but can be populated by a content provider or manually (go figure). This is the key in which the chart is written & can be changed by tapping the row to open a key picker. Changing the key also resets the attachment to be shown in its new key rather than the key it was last transposed to. Wild, right?

Lemme Swap This File Out

This will open the Import File dialog allowing you to change the file that is associated with the attachment. You can only choose a file that matches the file type of the existing file. No cross-contamination allowed, y\u{2019}all.

Details

This section shows when the attachment was created & last modified. (Not Shown) — because who cares about timestamps, amirite?
