Date format for the archive folder structure. Use an Autonomy date format string to name the folder that contains the archives. You can also use path separators to specify subfolders.
You can specify the archive folder structure using the following date formats:
YY 
Year (2 digits). For example, 99, 00, 01 and so on. 
YYYY 
Year (4 digits). For example, 1999, 2000, 2001 and so on. 
#YY+ 
Year (2 or 4 digits). If 2 digits are provided, then the YY format is used. If 4 digits are provided, then the YYYY format is used. For example, 07 is interpreted as 2007 AD and 1007 is interpreted as 1007 AD. 
#Y 
Year (1 to a maximum of 16 digits) and may be followed by "AD" or "BC". An apostrophe (') immediately before the year denotes a truncated year. For example, 2008, '97 (interpreted as 1997), 97 (interpreted as 97 AD), '08 (interpreted as 2008), 2008 AD and 200 BC. A truncated year with a BC identifier is invalid ('08 BC). 
#FULLYEAR 
Year (1 to a maximum of 16 digits). For example 8, 98, 108, 2008, each of which is taken literally. The year is taken relative to the common EPOCH (0AD). 
#ADBC 
Time Period. For example, AD, CD, BC, BCE or any predefined list of EPOCH indicators. Typically, the year specified using the above Year formats is interpreted as untruncated and relative to the EPOCH. For example, 84 AD is interpreted as 1984 AD and 84 BC is interpreted as 84 BC.
The only exception to this is when #YY+ and #ADBC are both used. In this case, the format is interpreted as untruncated even if the year was set to truncated by #YY+. For example, 99 AD is interpreted as the year 99 AD.
It is recommended you only use YY, YYYY or #FULLYEAR with #ADBC. 
LONGMONTH 
A long month, for example, January, February and so on. 
SHORTMONTH 
A short month, for example, Jan, Feb and so on. 
MM 
Month (2 digits). For example, 01, 10, 12 and so on. 
M+ 
Month (1 or 2 digits). For example, 1,2,3,10 and so on. 
DD 
Day (2 digits). For example, 01, 02, 03, 12, 23 and so on. 
D+ 
Day (1 or 2 digits). For example, 1, 2, 12, 13, 31 and so on. 
LONGDAY 
2 digits with a postfix. For example, 1st, 2nd and so on. 
HH 
Hour (2 digits). For example, 01, 12, 13 and so on. 
H+ 
Hour (1 or 2 digits). 
NN 
Minute (2 digits). 
N+ 
Minute (1 or 2 digits). 
SS 
Second (2 digits). 
S+ 
Second (1 or 2 digits). 
ZZZ 
Time Zone, for example, GMT, EST, PST, and so on. 
ZZZZZ 
Time Difference (1 to 9 digits). For example, +04 denotes 4 hours ahead of UTC. Other examples include +4, +04, +0400, +0400 MSD (the string MSD is ignored). A further example is +030, in this case the time differences is interpreted as 30 minutes. 
#PM 
AM or PM indicator (2 characters). For example, 2001/09/09 02:46:40 pm 
#S 
A space. 
Note: By default each directory will have a hashed directory structure (64 folders each containing 64 folders), to avoid slow file operations that can occur in some file systems when there are many files in a single folder. If you are using a short time interval, this may not be necessary. You can disable this using the ArchiveUseHashDir configuration parameter.
