Ok. It has to be something within these files???
It
is a filesystem issue or error that is almost certainly specific to those files, or their parent folder. I'm not guessing. I'm sure. I've encountered this issue many times in the past. It can, unfortunately, have a variety of causes. Probably the most common cause, aside from general filesystem errors or permissions issues, is from delayed write failures on the drive where the files are stored. This leaves the filesystem metadata and the file data on disk in an inconsistent state, and the files can get hopelessly locked.
If the same issues don't occur with all files on the filesystem (or same drive) then it is something broken in those particular files (or one of their parent directories). In
some cases (though this is relatively rare), it can be just that the volume format is hopelessly hosed and there is nothing that can be done other than to nuke the entire drive. This is much less likely when the files are on a network share, though (but still possible, the corruption or error could be on the system hosting the share).
Did you look at any of the results in the Google search I linked to above?
The most common ways to fix things like this are:
* Run chkdsk on the volume where the files are stored.
* To correct filesystem or network share permissions, and force the changes to apply to subfiles and folders.
* To copy them elsewhere and delete (if possible) the original source directory, then move them back to a freshly created directory.
* To do the same as above from Safe Mode (this is usually only possible if the files are on a local drive, not a network share).
* To do the above from the command line, referencing only the short filenames (8.3 style)
* To copy them elsewhere and then delete the original files one at a time.
* To do the above from the command line, referencing only the short filenames (8.3 style)
* To do the command line tricks from safe mode.
In rare cases, there may be little you can do other than to reformat the source volume.
