The invention belongs to the technical field of isomerization program interaction methods in a Windows system, and particularly relates to an isomerization program interaction method based on file names in the Windows system. By the isomerization program interaction method based on the file names in the Windows system, reading and writing conflict is avoided, and correct interaction is guaranteed. Basic programs involved in the system comprise an interface program (1.1), a computing program (1.2) and an isomerization program (1.3). The file names have a naming rule. The isomerization program interaction method based on the file names in the Windows system comprises the following steps of (1) determining an isomerization program document folder catalog; (2) setting interaction information of isomerization programs; (3) receiving N pieces of information by using an isomerization program P1; and (4) transmitting M pieces of information by using the isomerization program P1. The isomerization program P1 equals to an isomerization program P2, and the information of the isomerization program P2 and the information of the isomerization program P1 are transmitted and received by the isomerization program interaction method based on the file names in the Windows system. Compared with the traditional interaction mode, the isomerization program interaction method based on the file names in the Windows system has the advantages that isomerization program interaction success rate is greatly improved, and the isomerization programs can coordinate with each other and can be carried out correctly.
