I have a requirement, to have an iPad locked to a single folder view, with 1 level subfolders, each with a list of pdf files:
. ├── Bob Dylan/ │ ├── file1.pdf │ ├── file2.pdf │ ├── file3.pdf │ └── file4.pdf ├── Eric Clapton/ │ ├── file1.pdf │ ├── file2.pdf │ ├── file3.pdf │ └── file4.pdf └── Led Zeppelin/ ├── file1.pdf ├── file2.pdf ├── file3.pdf └── file4.pdf
I think of some pdf viewer which can allow one to create this tree, so that when iPad is locked into that app, one can only browser this simple tree and open these files, and nothing else.
So tried a number of pdf readers, but still did not meet the one which does it.
As I'm not native to Apple ecosystem, and not an Apple user myself, I thought maybe someone happens to know an appropriate app for this.
