To retrieve any lost files on Chromebook, one should first examine the Files application and check the trash for any recently deleted files. In case these lost files were stored in Google Drive, then one needs to access the Drive application and examine its trash section. It is possible that there might be an intact file version in another folder or synced device or backup as well. In case the files are lost due to storage issues, one should refrain from using that particular storage extensively.

In case of a supported Windows or Mac OS storage drive, Notchox can be taken into consideration for data retrieval.
