FAQ

No. It can be run directly from any disk e.g. from a USB drive. Data recovery software that requires installation does often not make much sense, because installing a program can overwrite deleted files on the computer.

Recover4all lists deleted files in the folder from which they were deleted. Of course you will look there first. But if you can not find them there, there is still a chance that they will show up in a blue folder. Those folders contain files that could not be assigned a position in the existing file system. So if you can not find your files in yellow or green folders, look for them in possibly listed blue folders.

No. Recover4all does deliberately not allow to recover files to the same drive, because the deleted files could be overwritten.

You can for instance recover to an attached USB drive. You can also recover to network drives which are mapped to drive letters.

Files that can not be opened are corrupted. The deleted files have either already been overwritten to some extent with other files or they could not be correctly reassembled.

Though Recover4all displays recovery chances to the best of its knowledge, even green files with "good" recovery chances can turn out to be corrupted. Example: file A is deleted and overwritten with file B. Recover4all will display file A as a red (overwritten) file. But if file B is later also deleted and overwritten, Recover4all will not find file B that overwrote file A. Recover4all will then show file A as a green (not overwritten) file.
