Abstract

A computer program product is provided. The computer program product includes a tangible storage medium readable by a processing circuit and on which instructions are stored for execution by the processing circuit for, upon receipt of a command relating to a file stored at a remote location, synchronizing the file between the remote location and a local device, determining whether a list of files linked to the file is stored in the local device, and, in an event the list is stored in the local device, synchronizing the files included in the list between the remote location and the local device.

Claims

1. A computer program product comprising a non-transitory tangible storage medium readable by a processing circuit and on which instructions are stored for execution by the processing circuit for:

upon receipt of a command relating to a file stored at a remote location, synchronizing the file between the remote location and a local device via a network;

determining whether a list of files linked to the file is stored in the local device, determining whether any of the files included in the list include additional files and determining whether a list of the additional files is stored in the local device; and

,

in an event the list and the list of the additional files are stored in the local device, synchronizing only data asynchronicities between the files and the additional files included in the list between the remote location and the local device such that only the data asynchronicities are transferred via the network from the remote location to the local device,

the synchronizing comprising generating a graphical user interface (GUI) identifying the file, providing a save button for instructing the local device to save replaced files or data, a verification button to issue a notice that a file transfer has been verified and an overwrite button to overwrite newer data or files, and displaying side-by-side local and remote listings for the list and the list of the additional files, and

wherein the file comprises a computer aided design (CAD) data assembly file and the files linked to the file comprise;

sub-assembly files relating to comprehensive aspects of the CAD data assembly;

first additional sub-assembly files linked to the sub-assembly files and relating to intermediate level aspects of the CAD data assembly; and

second additional sub-assembly files linked to the first sub-assembly files and relating to detail level aspects of the CAD data assembly,

the file, the sub-assembly files and the first and second additional sub-assembly files forming a family of files to be manipulated together.

2. The computer program product according to claim 1, further comprising:

in an event the list is not stored in the local device, extracting the list;

storing the list in the local device; and

searching for the files included in the list at the remote location.

3. The computer program product according to claim 2, wherein the searching is executed in a predefined directory at the remote location.

4. The computer program product according to claim 1, further comprising:

in an event the list of the additional files is not stored in the local device, extracting the list of additional files;

storing the list of the additional files in the local device; and

searching for the additional files included in the list of the additional files at the remote location.

5. The computer program product according to claim 4, wherein the searching is executed in a predefined directory at the remote location.

6. A system comprising:

a remote device at a remote location;

a local device;

a network; and

a processing circuit, the processing circuit being configured to;

upon receipt of a command relating to a file stored at the remote location at the local device via the network, synchronize the file between the remote location and the local device;

determine whether a list of files linked to the file is stored in the local device, determine whether any of the files included in the list include additional files and determine whether a list of the additional files is stored in the local device; and

,

in an event the list and the list of the additional files are stored in the local device, synchronize only data asynchronicities between the files and the additional included in the list between the remote location and the local device such that only the data asynchronicities are transferred via the network from the remote location to the local device,

the synchronizing comprising generating a graphical user interface (GUI) identifying the file, providing a save button for instructing the local device to save replaced files or data, a verification button to issue a notice that a file transfer has been verified and an overwrite button to overwrite newer data or files, and displaying side-by-side local and remote listings for the list and the list of the additional files, and

wherein the file comprises a computer aided design (CAD) data assembly file and the files linked to the file comprise;

sub-assembly files relating to comprehensive aspects of the CAD data assembly;

first additional sub-assembly files linked to the sub-assembly files and relating to intermediate level aspects of the CAD data assembly; and

second additional sub-assembly files linked to the first sub-assembly files and relating to detail level aspects of the CAD data assembly,

the file, the sub-assembly files and the first and second additional sub-assembly files forming a family of files to be manipulated together.

7. The system according to claim 6, wherein the system is configured to:

in an event the list is not stored in the local device, extract the list;

store the list in the local device; and

search for the files included in the list at the remote location.

8. The system according to claim 7, wherein the search is executed in a predefined directory at the remote location.

9. The system according to claim 6, wherein the system is further configured to:

in an event the list of the additional files is not stored in the local device, extract the list of additional files;

store the list of the additional files in the local device; and

search for the additional files included in the list of the additional files at the remote location.

10. The system according to claim 9, wherein the search is executed in a predefined directory at the remote location.

11. A computer program product comprising a non-transitory tangible storage medium readable by a processing circuit and on which instructions are stored for execution by the processing circuit for:

receiving a command relating to a file stored at a remote location and synchronizing the file between the remote location and a local device via a network;

determining whether a list of files linked to the file is stored locally, determining whether any of the files included in the list include additional files and determining whether a list of the additional files is stored in the local device;

synchronizing only data asynchronicities between the files and the additional files included in the list between the remote location and the local device by only transferrin the data asynchronicities via the network, in an event the list and the list of the additional files are stored locally; and

generating a graphical user interface (GUI) identifying the file, providing a save button for instructing the local device to save replaced files or data, a verification button to issue a notice that a file transfer has been verified and an overwrite button to overwrite newer data or files, and displaying side-by-side local and remote listings for the list and the list of the additional files.
