It is not always straight forward to determine if a data file or archive file is oversize (bloated). This means that there is data in the file that should not be there.
Generally over time your Attaché data will grow. This happens within financial years as your GL data grows (GL data resets each year), and across years as sub-module (Customers, Suppliers, etc.) data grows.
Files that are very large however (Gigabytes in size) should be monitored. Some of these files will clear at End of Year, like bankrec.dat. If this does not happen, please raise a case and refer to this article.
There is much that you can do to maintain your data, and maintaining your data through 'Housekeeping' procedures is essential to keep your Attaché system running smoothly and quickly. Refer to: Maintain my data.
This is especially the case to control the size of archive files and the space they can take up on Evo or CHS, refer to this article about archives on these systems:
If you are concerned about the size of your data files, compare the particular files across years. Then estimate whether:
For submodules: the size increase seems reasonable given the 'several years' that would be in the Last Year file, and the part years' worth of data that would be added in the Live Company.
For GL: the file size for the current year is broadly/proportionately similar to last year, if the number of transactions for the current year is similar to last year. That is, if your business has grown significantly, you should expect your GL data to be larger than last year.
If you think the file sizes are significantly larger, follow the steps in this article link to Compress your data.
If the file size does not change, then follow any other steps in the following article (and related articles linked to it) that relate to the particular file that you think is oversized, see the Maintain my data link above.
If you still cannot reduce the file size, raise a new case online and reference the title of this article.
