3584.1 | DECdecision file squish | PRAVDA::JACKSON | You run your mouth, I'll run my business brother | Mon Nov 05 1990 22:34 | 13 |
| Someone ( can't remember who) suggested the following to squish
a RDB/SNP file (this is from REGAL::DECDECISION)
$ mcr rdo
EXPORT 'decision$access_db.rdb' INTO 'decision$access_db.rbr
with extensions
IMPORT 'decision$access_db.rbr' INTO 'decisioN$access_db.rdb'
Dictionary is not used
End Import.

3584.2 | If only I had a DW terminal I'd know this? | COGITO::ZIKA | z | Tue Nov 06 1990 07:29 | 8 |
| Yes! This should work. This was also mentioned In an unrelated note in
RDB. Now to look at the DECdecision docs...
I will try the above but don't really expect to gain much. Since the
files are several months old not much data may have changed.
If this process does work I may start running it monthly or when disk
space gets low. -- Chris

SIXELs are typically already run length encoded, I don't know of a
tool to run length encode an existing file.
UIS files are structured binary files, and connot usually be
compressed, nor is there any compression tool.
OLB (and MLB) files can be compressed. See the documentation on the LIB
utility for how to compress it.

3584.4 | LZ Compression may fit the bill | 3D::VESPER | Is skiing more enjoyable? | Thu Nov 08 1990 09:05 | 12 |
| > Is there a way to compact ".SIXEL", ".SIX",
Do you need to be able to use the files in the compacted form?
If you are willing to use a decompress program before using
the data in the file, check out the LZ compression/decompression
utility in METOO::SW_TOOLS_CATALOG notes file. You can compress
any type of file with generally good results. Files which already
have some form of compression (run length encoding in SIXEL files,
for example) will not compress very much, if at all.
