This is a weird problem. Caused by interaction of cygwin 1.7 and
Perfect Disk 7.0 (defragmeter).
A couple of days ago, I was defragmenting my drive C: when I discovered
a copy of every cygwin's file with a naming convention of:
AY63D92E~orig.file.name~. The leading chars were 8 letters/numbers of
uppercase. The filename portion surrounded by the "~" character. This
happened only under the /cygwin tree while the MS-DOS (Win XP Pro) were
unaffected.
All of these files were "copies" of cygwin's files (link count == 1).
Now that Perfect Disk 7.0 is done with drive C:, I'm going to delete all
47,000 of these burgers.
This a weird interaction between 1.7 and Perfect Disk. The problem
stopped happening when Perfect Disk finished with drive C:. This is
"far" from a feature, a definite bug.
One thing to note: The mtimes of all of the duplicate files were
current. They did not reflect the mtime of the original file.
