   - Instruct your virus scanner to exclude your GAMS working directory. (this will work with any the GAMS version).   - Instruct your virus scanner to exclude your GAMS working directory. (this will work with any the GAMS version).
   - Instruct GAMS to use another file extension than ''​scr''​ for scratch files: Starting with distribution 22.9 the default file extension of intermediate files located in the ''​225?''​ directories is ''​.dat''​. The scratch extension is a parameter that can be changed with the GAMS option ''​ScrExt'',​ e.g. ''​gams trnsport scrext=tmp''​. Within GAMS code you get the scratch extension using ''​%gams.scrext%''''​Code Text''​.   - Instruct GAMS to use another file extension than ''​scr''​ for scratch files: Starting with distribution 22.9 the default file extension of intermediate files located in the ''​225?''​ directories is ''​.dat''​.

-  - Keep all files in memory instead of writing them to disk:  No large model scratch files need to be written to disk which can save time if you solve many models in your GAMS program. This in-core execution is activated by setting ''<​modelname>​.solvelink=5;''​ before the solve statement and by using cplexd (or any other in-core solver version) instead of cplex as your lp solver (just add the line option ''​lp=cplexd''​ to your model). Please note that this increases the amount of RAM required by your model and that CPLEX can not handle QCP models. Please note that currently only selected ​solvers are supporting in core operation.+  - Keep all files in memory instead of writing them to disk:  No large model scratch files need to be written to disk which can save time if you solve many models in your GAMS program.
