A
dir
ectory is a text string drawn fr
om the alphabet (a to z), digits (0 thr
ough 9), and the minus sign or hyphen (-). No blan
k or space characters ar
e permitted as part of a
di
rectory name. No distinction is made between upper and lower case. The first character must be a letter
.
•
A
dir
ectory does not actually exist until a file has been copied into that path.
• Unlike PC operating systems, the switcher permits a file and dir
ectory stor
ed on the switcher to have the same names.
• The curr
ent dir
ectory is based on a per-connection setting. It begins at the r
oot for each new IP session.
