That is a character special file. By convention, it should be in /dev. When you copy from it, you are trying to read from a device driver. A file system object like that is created with the mknod command, although HP-UX provides insf and mksf which really need to be used except in certain special cases. The 64 is the major number and this id's which driver you are trying to use. The HP-UX command lsdev will list all drivers with thier special numbers. lssf might also be able to tell you about it if it is valid. Be careful with special files. If you write to one, you could scribble on a disk.

NAME
approx-gc - garbage-collect the cache of Debian archive files SYNOPSIS
approx-gc [OPTION]... DESCRIPTION
approx-gc scans the cache created by approx(8) and finds files that are corrupted or no longer needed. With no options specified, these files are listed on standard output and removed from the cache. A corrupted file is one whose size or checksum does not match the value specified in the Packages or Sources file. An unneeded file is one that is not referenced from any distribution's Packages or Sources file. approx-gc may take several minutes to finish. OPTIONS
-c file, --config file Specify an additional configuration file. May be used multiple times. -f, --fast Don't perform checksum validation. -k, --keep, -s, --simulate Don't remove files from the cache. -q, --quiet Don't print file names. -v, --verbose Print the reason for removal of each file. EXAMPLES
To remove all unneeded or corrupted files from the cache: approx-gc --quiet This is run as a weekly cron(8) job. To list the files that would be removed from the cache, without actually doing so: approx-gc --keep FILES
/etc/approx/approx.conf Configuration file for approx and related programs. /var/cache/approx Default cache directory for archive files. SEE ALSO
