Can anyone recommend a free, simple to use file/folder lock programme.? ?
What OS would help. I assume is windows, so use the win sys stuff. Shared file access in Windows is managed by three distinct mechanisms: 1. Using share access controls that allow applications to specify whole-file access sharing for read, write or delete; 2. Using byte range locks to arbitrate read and write access to regions within a single file; and 3. By Windows file systems disallowing executing files from being opened for write or delete access. The semantics of share access controls in Windows are inherited from the original MS-DOS system (where sharing was introduced in MS-DOS 3.3) Thus, an application must explicitly allow sharing – otherwise an application has exclusive read, write and delete access to the file (other types of access, such as those to retrieve the attributes of a file are allowed.) For a file with shared access, applications may then use byte range locking to control access to specific regions of the file. Such byte range locks specify a region of the file (o
