File Undelete Library: recover deleted files on FAT, NTFS, and exFAT partitions
Undelete Library is well-tested, highly stable, and easy to use library for recovering (unerasing) deleted files and directories. It was developed as component for Altap Salamander file manager and is thoroughly tested by thousands of users on variety of operating systems with different setups.
The Undelete Library is available as dynamic linked library (DLL) or statically linked library (LIB) including complete source code (Microsoft Visual C++ 2013, 2015, and 2017). It can be used with C++, C#, Visual Basic, Delphi, and other languages including .NET.
Undelete Library 4.0
Undelete Library 4.0 is major library upgrade with long requested exFAT support. We used this opportunity to update library to current technology requirements. Library is now compatible with Windows 10. Complete source code undergone thorough refactoring and testing on all supported partition types. We also fixed several reported and newly discovered rare problems on some disk topologies (large volumes, small clusters, etc.). You can find new and improved features in list below.
