deleting hidden "io_mon.txt" file on H3C 7506E to free space

[Rick_HP]

Hello,

I am trying to upgrade my H3C 7506E, but I am short on space on the flash.  If I execute a "dir /all" I see:

Directory of flash:/

0 -rw- 31456820 Apr 27 2010 08:25:31 S7500E-CMW520-R6605P03.app
1 -rwh 864024 Apr 27 2010 08:47:15 io_mon.txt
2 -rwh 11972 Jun 17 2013 20:05:53 private-data.txt
3 -rw- 53653 Jun 17 2013 20:06:17 startup.cfg
4 -rw- 151 Jun 17 2013 20:06:03 system.xml

6 -rwh 716 Mar 25 2013 19:37:52 hostkey
7 -rwh 572 Mar 25 2013 19:37:55 serverkey

If I can get rid of the io_mon.txt I should have enough space, but it is a hidden file and therefore the delete command does not see the file.  Anyone got any ideas to work around the issue?

Well, make a backup, format the flash and copy back all files? Do a "boot-loader file",... "Save"...

Thanks, good suggestion.  I'm also surious what the file is.  I could not find anything in the documentation about a file of that name.  Nor anything about managing hidden files.
