The issue may happen when an unexpected error occurred during the upload process.

To delete the 0 KB files, do the following:

Admin Solution 1: Delete a specific 0 KB file

1. SSH login to SafeSync for Enterprise server (either appliance1 or appliance2).
2. Go to SafeSync OSDP bin directory.

   cd /opt/TrendMicro/OSDP/bin

3. Find the 0 KB file owner's user ID using the user's login name.

   sudo ./userTool.pl -u <user_login_name> show | grep "^ID:"

4. Find the user's personal folder ID (displayed as "object_id") using the user ID taken from previous step.

   sudo ./objTool.pl -u <user_id> show | grep "object_id:"

5. List all files under the user's personal folder using the user ID and object ID taken from the two previous steps. Find the file ID of 0 KB file, which is located at the beginning of the line containing the 0 KB file name.

   sudo ./objTool.pl -u <user_id>-<object_id> tree | less

   For example, if the 0 KB file name is "test.img", then its file ID is "5-111".

   5-11 folder !home
     			    5-111 file   test.img

6. Delete the file using the file ID.

   sudo /opt/TrendMicro/OSDP/Bin/objTool.pl -i <file_id> -f delete

Admin Solution 2: Delete all 0 KB files

1. SSH login to SafeSync for Enterprise server (either appliance1 or appliance2).
2. Run the command below to list all files with 0 byte size.

   mysql -uroot -psafesync -e "select concat(user_id, '-',  object_id) as object_id, name, (select name from osdp.users u where u.user_id = o.user_id) as belong_user_name from shard_1.objects o where size = 0 and type = 'file';"

3. Find the file's object_id from the result above and use the command below to delete the files.

   sudo /opt/TrendMicro/OSDP/Bin/objTool.pl -f -i <object-id> delete

End-User Solution

1. Log in to SafeSync User Portal.
2. Re-upload the file (with the same file name) and choose to overwrite the existing one.
