ARCHLine.XP cannot save a project with 100% security if the file is in a folder that is synchronized with the OneDrive file storage service.
Saving your ARCHLine.XP project is a complex, multi-step process, and OneDrive may try to sync while the save is detected while the Save is in progress. As a result, the project may be corrupted and show a file length of 0 because ARCHLine.XP cannot successfully save the project file.
Can the ARCHLine.XP project save folder still be on OneDrive?
It is possible, but intermittent data loss should be considered and is therefore not strongly recommended. In case of data loss, it is worth looking for the last read-back project backup in the Security Archive.
What is the purpose of the OneDrive cloud storage service?
OneDrive can be used for archiving purposes.
From version 2021 ARCHLine.XP supports the Google Drive cloud storage service, but in rare cases, data loss or file corruption may occur when using Google Drive.
