By referring to the project selection image 400 and the operator operating the input device 52, the following processing can be executed.・ Civil engineering design, condition setting of completed construction documents ・ History management of predetermined folder structure of delivered property ・ Selection of work project ・ Civil engineering design work ・ Selection of completed construction documents ・ History management of multiple work projects ・ Uniform skewer search possible Filing

In this embodiment, in all of the following steps, the electronic delivery creation flow button group 401 is included in the image, so that the operator can proceed with the work while confirming the work flow. it can. Further, the window 404 displays a folder structure that accommodates various files upon electronic delivery. Here, the operator may select a symbol in the folder structure to create a new folder, if necessary. The operator operates the input device 52 to select a desired project from the project list window 403 and clicks the decision button 405 to proceed to the next step.

In response to the click of the decision button 405,
The original file collection unit 11 is activated, and the created file and the file being created are stored and managed (step 302). When the original file collection unit 11 is activated, an image as shown in FIG. 5 is displayed on the screen of the display device 51. An image 50 is displayed on the screen of the actual display device.
On the left side of 0, the electronic delivery creation flow button group 401 and the work guide window 402 shown in FIG. 4 are displayed. With reference to this image, the operator operates the input device 52 to collect necessary files. In this embodiment, the original file and the PDF file are associated with each other based on the information when the PDF file was created from the original file. The association between the PDF file and the original file is stored as management information and used in file naming described later. The information on the file associated with the predetermined directory and the information on the association are the directory information 1
It becomes 2.

In FIG. 5, a column 501 shows folders in which files should be registered in a directory structure. The file is finally written in the medium 26 in a form in which a predetermined file is accommodated in a folder forming this directory structure. Determining a file to be stored in a predetermined folder in the directory structure is called file registration. In the upper right part of the column 501, a file list area 50 in which bibliographic information of files to be accommodated in the folder specified in the column 501 is arranged.
Two are provided. In the lower right part of the column 501,
An area 503 for the original file is provided in which the bibliographic information of the original list of the selected files among the files listed in the area for the file list is arranged.

The user refers to the image 500 and refers to the column 50.
By clicking a predetermined folder in 1, the folder in which the file should be stored is designated (for example, reference numeral 5
Then, a common dialog or the like is activated to display a list of files, and a desired file is moved to the file list area 502 by dragging and dropping. Furthermore, a button placed at the beginning of the file in the area 502 (see, for example, reference numeral 512)
Click, specify the file, and start the common dialog to display the original file
It is moved to the original file area 503 by dragging and dropping. As a result, the specified file displayed in the file list area 501 and the original file are associated with each other.
In this way, the association between the folder and the file in the directory structure when accommodated in the medium 26, and the association between the file and the original file are stored as the directory information 12. By the above association, the folder in which the original file should be stored is also determined.

In this way, after the collected original files are associated with the necessary folders and the required files are associated with each other, the "file naming" button in the electronic delivery creation flow button group 401 is clicked. , The file naming unit 13 is activated, and the image shown in FIG.
Displayed on the screen. Here, the file name is given to the associated file according to the naming rule input by the user and the predetermined naming rule 14 (step 303). For example, when a predetermined file name is specified for each delivery destination, if a plurality of rules are set in advance, the file name can be automatically given. In addition, the associated PDF file and its original file are automatically named. The file naming here means the medium 26.
It means that the file name when writing to is given,
It does not rename the file name at this point.
That is, in the file naming process, the file name when writing to the medium 26 is
It will be stored in association with the file.

FIG. 6 is a view showing a part of an image displayed when naming a file. In FIG. 6, as in FIG. 5, the electronic delivery creation flow button group 401 and the work guide window 40 shown in FIG. 4 are actually provided on the left side thereof.
2 are arranged. In the image 600, in addition to the directory display field 601, an arbitrary naming area 602 for inputting a file name so as to individually give a file name to a specified file and a file in a folder are automatically added. An area 603 for automatic naming for inputting necessary rules is provided so as to give a file name. In the area 602 for arbitrary naming, the operator may input an arbitrary name in the input field. Further, in the area 603 for automatic naming, the operator inputs the start number and the number of digits of the fixed character string and serial number character string of the name given to each file included in the folder. . Of course, instead of the number of digits, the end number may be entered.

By using the fixed character string and the serial number, for example, "REPORTnn" for the files in the folder.
It becomes possible to give a name (“REPORT” is a fixed character string, and “nn” is a number increasing from the start number to the end number). When using the automatic naming, a predetermined folder in the field 601 indicating the directory structure may be designated, and the start number and the number of digits of the fixed character string and the serial number character string may be defined for the folder. Further, in the file name display field 604, the file name of the life name (see reference numeral 611) and the file name after the naming (reference numeral 612).
(See) is enumerated.

When file naming is completed and the operator operates the input device 52 and clicks the "input management information" button in the electronic delivery creation flow button group 401,
The management information input image is displayed on the screen of the display device 51. Here, it is possible to input the necessary bibliographic items such as the name of the medium to be finally written in the medium, the type, and the created software. Also, in order to confirm the contents of the file, the viewer can be started by specifying the file. In addition, a list that can confirm the association between the PDF file and the original file in the image is included. The user may refer to the image and input a character or number in a predetermined field (step 304).
The management information is written in the medium 26 as an XML file. In the present embodiment, step 30
In No. 4, the input information is not converted into an XML file and is held in a text state. This makes it possible to easily correct the input management information when the next file check includes an error.

After the generation of the XML file (conversion to the XML file) is completed, when the operator clicks the "check" button in the electronic delivery creation flow button group 401 in the image, the file check unit 15 is activated, The created file is checked (step 3)
05). In the present embodiment, for example, the following items can be checked. Check the characters used in the report (original file) Check XML prohibited characters and character string length Check required items for management information Check for missing DTD version of management information Check file name JPEG file ( Check the compression ratio of (photo)

When checking a file, first, as shown in FIG. 7, a window 70 showing items to be checked.
1 opens. Here, by adding a check mark to a check box (see reference numeral 711, for example) and clicking an “execute” button (not shown), the check for that item is executed. The check results (messages such as errors) are displayed in the check result window 8 as shown in FIG.
00 is displayed. This check result window 800
In, the caution item (see reference numeral 801) corresponding to the error message, the folder name or file name of the file including the caution item (reference numerals 802, 80)
3) can be displayed. In the present embodiment, by clicking a desired message among the messages regarding the individual files (see reference numerals 811 to 814) listed in the check result window 800, the file related to the message can be opened. Can be corrected.

Next, among the file checks according to the present embodiment, the compression rate check described above will be described in more detail. FIG. 9 is a flowchart showing the processing executed when checking the compression ratio of an image file. In checking the image file, first, the data size when the image file data is expanded and displayed in the viewer is specified (step 90).
1) Then, the data compression rate, that is, (original file size) / (decompressed file size) is calculated (step 902). If this data compression rate is within a predetermined range (for example, compression rate ≧ 1/8) (step 90)
If the answer is 3 (Yes), the check for the file ends. On the other hand, if it is not within the predetermined range (for example, compression rate <1/8: No in step 903), a message (error message) indicating a warning is generated,
This is added to the list in the check result window 800 (step 904). This message includes, for example, "compression ratio is higher than 1/8", its folder name and file name (FIG. 8).
821). Further, the folder name and file name related to the above warning are stored (step 905).

As described above, according to the present embodiment, it is possible to check the compression ratio of image data such as a photograph, which is difficult for the user to know only by referring to the attribute (property) of the file. This makes it possible to prevent the data stored in the medium 26 from being out of the standard.

Next, with reference to FIG. 10 and FIG. 11, a description will be added regarding checking and correction of document files and the like. Note that the processing of FIG. 10 and FIG. 11 is targeted for files that handle text. Here, the data in the file is scanned (step 1001), and it is determined whether an error has occurred with respect to the designated check item (step 1002). If an error has occurred (Yes in step 1002), a message (error message) indicating a warning is generated (step 10).
03), this is added to the list in the check result window 800 (step 1003). Here, the error message includes the folder name and the file name to be arranged, but in checking the document file and the like, the position (page, line, etc.) where the error has occurred is also known. Therefore, in step 1004, in addition to the folder name and file name, the position where the error has occurred is also stored (step 1004). Such processing is repeated until the end of the file (see step 1005).

When referring to the message of the file listed in the check result window 800 and modifying the file, the user specifies the desired message (eg, reference numeral 814 in FIG. 8) in the message in the list. Then (step 1101), the application that created the file is specified (step 1102), and the application is activated (step 1103). Next, if the position where the error has occurred (error part) such as a document file is stored, the position is specified (step 1104), and the error part and its periphery are included in the file edit screen. The image is displayed (step 1105). Therefore, the user may operate the input device and make necessary corrections (step 110).
6). After the modification is completed, the process is completed by closing the application (step 1107). Also for image files, the viewer can be opened to check the images. In addition, the image editing software may be opened to make necessary corrections such as changing the compression ratio.

In the present embodiment, basically, when the error is eliminated, that is, when the error message is not listed in the check result window, it is possible to proceed to the next step, that is, the creation of the delivery data. .
However, in some cases, it may be arranged that a predetermined item may be out of the standard by a meeting with the orderer. Therefore, a check box (eg, reference numeral 821) placed at the beginning of the message
By attaching a mark, it is possible to ignore this and proceed with the processing. In addition, the log of the check process can be saved by a predetermined operation by the operator. In the present embodiment, the log output format is a CSV (Comma Separated value) file.

After that, the operator operates the input device 52 so that the electronic delivery preparation flow button group 401
When the "delivery data creation" button therein is clicked, the delivery data at the final stage before writing to the medium is created (step 306). Here again, an image (not shown) for creating delivery data is displayed on the screen of the display device 51. By referring to the image, the operator can set options such as attaching a viewer for reading data. In addition, the created delivery data,
It can also be instructed to register in a designated DB.

Next, when the operator operates the input device 52 to click the "delivery media creation" button in the electronic delivery creation flow button group 401, a plurality of delivery data items are recorded in accordance with the type of medium in which the data is written. It is judged whether or not it is necessary to allocate the blocks to the blocks (step 307). It is also possible to allocate the blocks to desired blocks in accordance with the operator's input. By clicking the "Generate delivery media" button,
The image as shown in is displayed.

On the right side of the image shown in FIG. 12, similarly to the image 400 shown in FIG. 4, the electronic delivery creation flow button group 4 is displayed.
01 and work guide window 402 are included. The user selects a predetermined folder (for example, reference numeral 1211) from the column 1201 indicating the directory structure for storing files in the medium, and selects the medium (see reference numerals 1203 and 1204) for storing the folder in the right column 1202. After selecting from, "Register" button 1221
By turning on, the selected folder is displayed in the display column (for example, reference numeral 1203) of the selected medium while maintaining the directory structure.

In this way, when the medium to accommodate each folder is determined, for example, the medium "create" button (not shown) is turned on by the user, and data writing to the medium is started. When writing media,
The file determined to be placed in the folder forming the predetermined directory structure in the collection of the original files (see step 302) is the medium designated in step 307 with the file name given in step 303. Written in. Further, the management information input in step 304 is converted into an XML file, and the XML file is written in the designated medium. After that, when the "virus check" button in the electronic delivery creation flow button group 401 is clicked, an image including a button for instructing writing to the medium and a button for starting the virus check is displayed. When the button is turned on, the selected virus check software is started. The virus check software that was launched is
A virus check is performed on the delivery data written on a medium such as a CD-R (step 308).

When the "label print" button in the electronic delivery creation flow button group 401 is clicked, a label attached to a medium such as a CD-R can be printed. Here, the operator may input a title or the like in the input field of the image (not shown) displayed on the screen of the display device 51, or the existing management information may be used.
In this way, the label on which the necessary information such as the title is printed is output from the printer 54.

According to the present embodiment, by designating the message displayed in the checklist, the file relating to the error can be opened. In particular, in a document file or a tabular file, an error location is specified and an image including the error location is displayed. Therefore, the user can easily find and correct the error location. Further, according to the present embodiment, the management information is held in a text state at the time of checking. Therefore, even if an error has occurred in the management information, the management information can be opened and corrected by the text editing software.

Furthermore, according to the present embodiment, it is possible to check whether the compression rate of the image file is within the standard. In particular, it is particularly useful to be able to check such an error because the image compression rate may not be known only by referring to the file attribute.

The present invention is not limited to the above embodiments, and various modifications can be made within the scope of the invention described in the claims, and these are also included in the scope of the present invention. It goes without saying that this is what is done. For example, in the above embodiment, when collecting original files,
Although the folder in which the file should be placed is specified, the present invention is not limited to this, and the file may be actually stored in a separately created directory at the time of collecting the original files.

Further, the virus check may be executed before writing the delivery data to the medium. Further, in the above embodiment, the delivery data is written in the medium, but the present invention is not limited to this, and the delivery data may be delivered to another computer via the network. Not to mention good things.
