Abstract

According to one embodiment, a system includes a first electronic apparatus and a second electronic apparatus. The first electronic apparatus causes an external storage medium to store first information which controls possibility of writing of a file to the external storage medium in units of file. The second electronic apparatus determines possibility of the writing of a requested file to the external storage medium based on the first information, write the requested file to the external storage medium if the requested file is determined to be capable of being written, and prohibit the writing of the requested file to the external storage medium if the requested file is determined to be incapable of being written.

Claims

1. A system comprising:

the second electronic apparatus comprising;

a second connector in which the external storage medium is connectable; and

a second hardware processor configured to

accept a request for writing of a file to the external storage medium,

determine possibility of the writing of the requested file to the external storage medium based on the first information stored in the external storage medium,

write the requested file to the external storage medium if the requested file is determined to be capable of being written, and

prohibit the writing of the requested file to the external storage medium if the requested file is determined to be incapable of being written.

2. The system of claim 1, wherein:

the first information comprises a first condition indicating a condition under which the writing of the file to the external storage medium is permitted, and a second condition indicating a condition of a file which should be excluded from files meeting the first condition; and

the first hardware processor of the first electronic apparatus is capable of setting the first information comprising the first condition and the second condition, for each external storage medium.

3. The system of claim 2, wherein:

the first condition comprises at least one of a file name, an extension, a latest date and time of updating, number of files, a total file size and a size per file; and

the second condition comprises at least one of a file name, an extension and a latest date and time of updating.

4. The system of claim 1, wherein the second hardware processor of the second electronic apparatus is configured to determine the requested file incapable of being written to the external storage medium, if the first information is not stored in the external storage medium.

5. The system of claim 1, wherein:

the first information comprises a first condition indicating a condition under which the writing of the file to the external storage medium is permitted, and a second condition indicating a condition of a file which should be excluded from files meeting the first condition; and

the second hardware processor of the second electronic apparatus is configured to determine the requested file capable of being written to the external storage medium, if the requested file meets the first condition and does not meet the second condition.

6. The system of claim 5, wherein:

the first condition comprises at least one of a file name, an extension, a latest date and time of updating, number of files, a total file size and a size per file; and

the second condition comprises at least one of a file name, an extension and a latest date and time of updating.

7. The system of claim 1, wherein the second hardware processor of the second electronic apparatus is capable of accepting the request for the writing of the file to the external storage medium in units of folder, and writes the file determined to be capable of being written, of the files in the folder, to the external storage medium.

8. An electronic apparatus comprising:

a connector in which an external storage medium is connectable; and

a hardware processor configured to

accept a request for writing of a file to the external storage medium,

determine possibility of writing of the requested file to the external storage medium based on first information stored in the external storage medium to control the possibility of the writing of files to the external storage medium in units of file,

write the requested file to the external storage medium if the requested file is capable of being written, and

prohibit the writing of the requested file to the external storage medium if the requested file is incapable of being written.

9. The electronic apparatus of claim 8, wherein the hardware processor is configured to determine the requested file incapable of being written to the external storage medium if the first information is not stored in the external storage medium.

10. The electronic apparatus of claim 8, wherein:

the first information comprises a first condition indicating a condition under which the writing of the file to the external storage medium is permitted, and a second condition indicating a condition of a file which should be excluded from files meeting the first condition; and

the hardware processor is configured to determine the requested file capable of being written to the external storage medium if the requested file meets the first condition and does not meet the second condition.

11. The electronic apparatus of claim 10, wherein:

the first condition comprises at least one of a file name, an extension, a latest date and time of updating, number of files, a total file size and a size per file; and

the second condition comprises at least one of a file name, an extension and a latest date and time of updating.

12. The electronic apparatus of claim 8, wherein the hardware processor is capable of accepting the request for the writing of the file to the external storage medium in units of folder, and writes the file determined to be capable of being written, of the files in the folder, to the external storage medium.

13. A method executed by a system configured by a first electronic apparatus and a second electronic apparatus, the method comprising:

causing, by the first electronic apparatus, the external storage medium to store first information which controls possibility of writing of files to the external storage medium in units of file;

accepting, by the second electronic apparatus, a request for writing of a file to the external storage medium;

determining, by the second electronic apparatus, possibility of the writing of the requested file to the external storage medium, based on the first information stored in the external storage medium;

writing, by the second electronic apparatus, the requested file to the external storage medium, if the requested file is determined to be capable of being written; and

prohibiting, by the second electronic apparatus, the writing of the requested file to the external storage medium, if the requested file is determined to be incapable of being written.

14. The method of claim 13, wherein:

the first information comprises a first condition indicating a condition under which the writing of the file to the external storage medium is permitted, and a second condition indicating a condition of a file which should be excluded from files meeting the first condition; and

the causing, by the first electronic apparatus, the external storage medium to store the first information comprises setting the first information comprising the first condition and the second condition, for each external storage medium.

15. The method of claim 14, wherein:

the first condition comprises at least one of a file name, an extension, a latest date and time of updating, number of files, a total file size and a size per file; and

the second condition comprises at least one of a file name, an extension and a latest date and time of updating.

16. The method of claim 13, wherein the writing, by the second electronic apparatus, the requested file comprises determining the requested file incapable of being written to the external storage medium, if the first information is not stored in the external storage medium.

17. The method of claim 13, wherein:

the first information comprises a first condition indicating a condition under which the writing of the file to the external storage medium is permitted, and a second condition indicating a condition of a file which should be excluded from files meeting the first condition; and

the determining, by the second electronic apparatus, comprises determining the requested file capable of being written to the external storage medium, if the requested file meets the first condition and does not meet the second condition.

18. The method of claim 17, wherein:
