Abstract

A link to a shared version of a local file is inserted into metadata of the local file. The local file may be a copy of a shared file and/or a local file that is designated to be shared. For example, when a local file is uploaded to a shared location for collaboration, a link to the shared location is automatically inserted into metadata of the local file. A local copy of a shared file may be created by downloading the shared file to a local data store. A link to the shared location is automatically inserted into the locally stored. When the local file is opened, the link within the metadata may be used to access the version of the local file at the shared location. Changes made to the local file and/or shared version of the file may also be synchronized.

Claims

1. A method comprising:

detecting that a copy of a local file stored at a first location is attached to an electronic message;

in response to the detection, providing an upload option for display within the electronic message;

in response to receiving a selection of the upload option, uploading and storing a shared version of the local file at a shared location;

in response to storing the shared version of the local file at the shared location;

creating a link comprising an address that represents a location of the shared version of the local file at the shared location; and

inserting the link into metadata of the local file that is stored at the first location such that the link within the metadata of the local file is used to identify that the local file is shared and is used to access from the local file at the first location the shared version stored at the shared location; and

in response to opening the local file after the link is inserted within the metadata and identifying that the local file is shared using the link, causing a user interface that includes a selectable option to be presented, the selectable option enabling a selection to open the shared version of the local file that, when selected, opens the shared version of the local file at the shared location using the link.

2. The method of claim 1, further comprising synchronizing the local file and the shared version of the local file when the shared version of the local file is different from the local file.

3. The method of claim 1, further comprising storing a cached version of the shared version of the local file within a cache such that when changes are made to the cached version, the changes are synchronized with the shared version of the local file.

4. The method of claim 1, wherein inserting the link into the metadata of the local file comprises inserting the link into the metadata in a file header of the local file.

5. The method of claim 1, wherein causing the user interface that includes the selectable option to be presented in response to opening the local file after the link is inserted within the metadata and identifying that the local file is shared using the link comprises:

determining whether the shared version of the local file is a different, more recent version than the local file; and

causing the user interface that includes the selectable option to be presented further in response to a determination that the shared version of the local file is a different, more recent version than the local file.

6. The method of claim 5, wherein the user interface further includes an indication that the shared version of the local file is a different, more recent version than the local file.

7. Computer storage memory storing computer-executable instructions for:

detecting that a copy of a local file stored at a first location is attached to an electronic message;

in response to the detection, providing an upload option for display within the electronic message;

in response to receiving a selection of the upload option, uploading and storing a shared version of the local file at a shared location;

in response to storing the shared version of the local file at the shared location;

creating a link comprising an address that represents a location of the shared version of the local file at the shared location; and

inserting the link into metadata of the local file that is stored at the first location such that the link within the metadata of the local file is used to identify that the local file is shared and is used to access from the local file at the first location the shared version stored at the shared location; and

in response to opening the local file after the link is inserted within the metadata and identifying that the local file is shared using the link, causing a user interface that includes a selectable option to be presented, the selectable option enabling a selection to open the shared version of the local file that, when selected, opens the shared version of the local file at the shared location using the link.

8. The computer storage memory of claim 7, wherein a second file is stored at the shared location, and in response to the second file being downloaded to a local data store associated with the first location:

creating a link comprising an address that represents a location of the second file at the shared location; and

inserting the link into the metadata of the second file.

9. The computer storage memory of claim 7, further storing instructions for synchronizing the local file and the shared version of the local file when the shared version is different from the local file.

10. The computer storage memory of claim 7, further storing instructions for storing a cached version of the shared version of the local file.

11. The computer storage memory of claim 7, wherein inserting the link into the metadata of the local file comprises inserting the link within the metadata in a file header of the local file.

12. The computer storage memory of claim 7, wherein the instructions for uploading and storing the shared version of the local file at the shared location comprises:

automatically setting one or more permissions for the shared version of the local file stored at the shared location; and

providing a change permissions option to enable modification of the one or more permissions.

13. A system comprising:

a processor; and

a memory coupled to the processor and storing computer-readable instructions that, when executed by the processor, cause the processor to;

in response to a local file being stored at a first location and a shared version of the local file being uploaded and stored at a shared location, create a link comprising an address that represents a location of the shared version of the local file at the shared location, the shared version of the local file being uploaded and stored in response to detecting that a copy of the local file is attached to an electronic message and receiving a selection of an upload option provided for display within the electronic message upon the detection;

insert the link into metadata of the local file, wherein the link indicates that the local file is shared and is used to access from the local file at the first location the shared version of the local file at the shared location; and

in response to opening the local file after the link is inserted within the metadata and identifying that the local file is shared using the link, cause a display of a user interface that includes a selectable option, the selectable option enabling a selection to open the shared version of the local file that, when selected, opens the shared version of the local file at the shared location using the link, wherein the user interface further includes an indication that a different version of the local file exists at the shared location when the shared version of the local file differs from the local file.

14. The system of claim 13, wherein the memory stores further computer-readable instructions that, when executed by the processor, cause the processor to synchronize the local file and the shared version of the local file.

15. The system of claim 13, wherein a second file is stored at the shared location that is downloaded to a local data store associated with the first location for storage, and the memory stores further computer-readable instructions that, when executed by the processor, cause the processor to:

in response to the second file being downloaded to the local data store associated with the first location;

create a link comprising an address that represents a location of the second file at the shared location; and

insert the link into the metadata of the second file downloaded and stored to the local data store.

16. The system of claim 13, wherein the local file is stored at the first location on a computing device, and the shared version of the local file is stored at the shared location on a network share remote from and accessible by a plurality of computing devices including the computing device.
