Hi,
There are several command-line defragmenters (gui as well) available for
windows that are able to defragment certain files or directories only, like:
http://www.defragmentor.com/dmlcl/en/home.asp
http://support.microsoft.com/?kbid=283080
or you may like to create your own routines
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/fileio/fs/defragmenting_files.asp
I used such tool (first link above) and was able to defragment live
sqlite databases varying from 400kB to 12GB. A large (5GB+) database
indeed generally consist of hundreds of fragments if it was slowly
build, so it may be worth the effort.
kind regards,
Rene

Hi SQLiteUsers
Developing MFC Application (Small Business Accounting Application)
(developed using Visual Studio)
- App will run on Windows 98/2000
- App uses SQLite database files for storage of data
- It will have one database for each company accounts/info. So if accounts
of 10 companies, then info will be in 10 different SQLite DB files.
- All Database files on same disk.
- User of App may create more company file for accounts of another company.
- User of App may open any existing company file and enter/modify
transactions through different GUI screens.
- User closes file and may open another company file and enter/modify
transactions through different GUI screens.
After using such application, all used SQLite DB files gets fragmented.
How to avoid such fragmentation ?
Is there any feature, to pre-allocate disk-space to SQLite database file so
that initially some free space will be allocated to new file ?
Is there any feature, so that when database file gets filled, everytime
automatically increment file size by say 25% or 40% of size ?
FYI: Such pre-allocation of space and automatic incrementing file size is
provided for Database files in SQLServer, Oracle etc.
