Guy,
My "Ms70form.dta" file = 3.5 Mb in size and the "Ms70expl.dta" file is even 5.5 Mb.
Much like the Windows Registry dta files will only slightly realy shrink when Entries
are deleted from its dta's, neither will the MSK dta files shrink when you delete formulas.
This is a property of {the machine language being used in} the dta file format.
So, therefore and that's why you will have a large formula dta or whatever dta files.
Also dta's growing into unlimmited (!!!!) -and therefore not very practicle- file size(s).
The slowdown in Windows or in MSK achieved from OS reading these larger
dta files are not worth the mentioning here, since that the dta's aren't contstantly
being adressed, neither when loaded or when on disk. Contrairy, on the occassion
when they are being addressed, directly in MEM or on disk, then a too large file do
can slow down your process(es) tremendously. On program startup f.e., the dta files
will have to be loaded in MEM first and later, on a program or function call, is when
the OS will have to dig through the {immense} file content, eg to be able to address
the Entry.
A direct way to clean the MSK dta files is not at hand, neither in MSK nor in MS.
The MS utility RegClean {or utilities alike} will not work on dta files, other than on
the two(2) default Window's Registry dta files. And then these utilities aren't hardly
capable enough to have the Registry dta's shrink much in file size.
Workaround
There is a workaround to clean and/or to shrink the dta file {in} size, that can be
achieved as follows, by :
1) Exporting the Entries, to separate dta files{example: if you currently have 258
custom formulas, then you can export all in one lumb to one separate export file,
or to 258 single dta files or by using Copy & Paste or the Print button to print
all to a textfile.
then
2) replacing the current formula dta file for a previously made back up copy of
an original formula dta file{one that was created on a first install}
then
3) Importing the in step 1 exported formulas singly or in one lumb back into the
program, eg into the new back up copy {mentioned in step 2}, that you can now
use for the file "Ms[programversion]Form.dta". Use the Indicator Builder's Import
Tool or manualy, Copy+Paste from the forementioned text file. Use the ScripIt
program to automate the latter.
Ps: do not give up on your formula building, while now at the end, the end of the
tunnel is also in view sight.
