The Essential Project Forum

Good day,

When I try to save Protege project after working on it I keep on getting the following error:

Errors found performing operation.

1. Error saving project. Classes file name: essential_baseline_v6_15.pont. Instances file name: essential_baseline_v6_15.pins
Exception class java.io.IOException. Message: Delete of existing C:\standalone_essential_v615\standalone_essential_v615\essential_baseline_v6.15\essential_baseline_v6_15.pont failed

See console and log for more details.

What could be the ptoblem.

Thank you

Regards
Rodney

Looks like an OS level problem : do you have access rights to delete this file ?

Good day,

I am not sure if I have access rights to delete this file but I will check.

A Protege project consists of 3 files. *.pprj, *.pins, *.pont. Project, Instances and Ontology. All three are required. If I recall correctly, inside the PPRJ are references to the file names of the related PINS and PONT file. If you rename the files outside of Protege then this can break the relationship. If this might be the cause, then to resolve this, you will need to rename the files back to the original names.

Otherwise JMK's suggestion of local file permissions is a good shout.
