Hello Milos,
MATLAB places a limit of up to 20 open files in order to conserve static memory allocation.
It would be ideal to limit the number of files open simultaneously to 20. There is no limit to the number of files you can write, only to the number of files you can open at the same time.
This limit can be changed, but at your own risk. To do so, follow these instructions:
- Change MATLAB directory to /matlab/%release%/toolbox/eml/lib/matlab/iofun/private/
- Open “fileManager.m”
- Locate the function “MAXFILES” (In MATLAB R2022a, go to line 325). This function contains the following code:
n = coder.const(FIDCLS(20));
4. Edit this to the number you need. It can be up to 125.
5. Save this file and restart MATLAB.
Please note that this change needs to be re-implemented after every MATLAB update.
Hope this helps.
Regards,
Prateek
