When will the abApps service end?
We
will stop providing all technical support for Acer BYOC Apps (abApps)
on
September 30, 2018. We heavily encourage you to back up all photos
and documents in abPhotos and abDocs to your local storage. Files from
other abApps will still be able to be found in their original devices
without being affected.
The photos backed up via abPhotos are actually stored in
"abPhotos folders" in the C drive of [Users/This PC name/Pictures] on
your
Personal Cloud Storage (PCS). If you've changed its default storage location, you can find your backed up photos through the following steps:
Launch abPhotos on your PCS > click the Acer ID on the
upper-left corner > Device > click the backup storage location
link under PCS to find all your photos.
The documents synced to abDocs are actually stored in the PC
from which they were originally uploaded. If you can't find the location
of the original document in the abDocs app on your PC or the backed up
documents on other PCs, you can download those documents by signing into
abDocs on the other PCs and then following these steps:
Click and select the document in abDocs > Edit >
Download as > choose the storage location on your PC where you wish
to back up the file.
