Windows long path converts to "******~*" format, WHY??

[mike-yue]

Hi Fellows,
I have a program which does checking audio files in folders
recursively. An interesting thing about this program is that it
printed out the full path of files not in FULL format.

e.g.
A file's location is here:
R:\AAP_1_3\main\cycle4_M3_12JAN2009\data\targets\Regression
\TI_10file_test\rec_aec\stereo\XDAIS_RELEASE\16KHF_16KREF
\fs256\CONFIG607\small_dropouts_in_ref.wav

But the program printed it out this way:
R:\AAP_1_3\main\cycle4_M3_12JAN2009\data\targets\Regression
\TI_10file_test\rec_aec\stereo
\XDAIS_~1\16KHF_~2\fs256\CONFIG~1\small_dropouts_in_ref.wav

The source code I have in hand now could not reproduce the issue
happened before, but I don't know how the issue gone.If I don't know
why it may occurs sometime again.

Thanks

Mike

Just checked out an old tagged code and built the executable.
It DOES print out path with "~". But, when I was trying to debug the
program, everything is fine - the path variable and printout are all
full-path.
I know windows have a path length and limit thing, and windows do
convert path into that format "******~*" sometime, but it should not
happen in the program.

Any thoughts?

Thanks
