Files (MS Office document (Word, Excel, PowerPoint, Outlook) types (doc, docx, ppt, pptx, xls, xlsx, pst, etc.), photos (JPG, PNG, ICON, TIF, BMP, RAF, CR2, etc.), videos and audios (MPG, MP4, MP3, MTS, M2TS, 3GP, AVI, MOV, RM, RMVB, etc.), compressed files (rar, zip, etc.), PE files (exe, dll, lib, etc.) and so on.) are quite likely to be recovered if no new data are fed into this partition. If deleted files and directories were stored in a system disk, we suggest shutting down your computer and remove your hard drive to another computer to recover your data. It is because that new data might feed into the system disk at any time (new files written from virtual memory or other application programs may cover and damage the deleted files). If the deleted files were stored in the system disk, it is recommended to close all the running application and not view files in explorer to prevent feeding any new files. For example, when you open a directory containing image files, the system will write new Thumb.db files into your partition and damage your deleted data.
What does shift delete do?
In Windows Explorer, if pressed with objects selected, such as files and folders, this will bypass the recycle bin and delete the selected objects permanently. Alternatively, holding shift and selecting the delete option in the context menu of the selected objects will achieve this. Retrieving deleted objects after this is only possible using recovery software.
