Open in creating temp files to Acrobat file structure
I have noticed that if I “open in” a pdf a file from another source (GoodReader) I cannot change any file attributes (rename, duplicate, delete) withing Acrobat on ios. Looking at the IOS file structure, I see this “open in” file appearing more like a temporary file on the PDF side. If I side load the PDF from from ios file manager it works as intended.
If you use "Open in" from GoodReader (or any other iOS app), the PDF document will be opened in Acrobat Reader without making a local copy.
For example, please try the following steps.
1. In the source app, open a PDF document.
2. Select "Open in" to open the PDF document in Acrobat Reader.
3. Make changes to the PDF document (e.g. adding Highlight annotations) to the PDF document in Acrobat Reader.
4. Close the PDF document. Acrobat Reader saves pending changes to the PDF document.
5. Go back to the source app (in your case, GoodReader).
6. Open the PDF document in the source app.
You should see the changes that you've made in Acrobat Reader.
"I cannot change any file attributes (rename, duplicate, delete) within Acrobat on ios."
It sounds like you are looking at the PDF document in Acrobat Reader's Home > Recent file browser, which shows recently opened documents. But if you tap "Files" in the bottom bar and go to Locations > On This iPad/iPhone, you can see that there is no permanent copy of the PDF document created within Acrobat Reader.
To perform any file operations (e.g. rename, duplicate, delete), please go back to the source app (in your case, GoodReader) that the original PDF document belongs.
Because Acrobat Reader doesn't "own" PDF documents that are stored in other apps, it cannot rename, duplicate, or delete those PDF documents.
