Data Compression for Consignment Stores

Learning a few basic Windows tasks will save money and avoid delays by making your business less reliant upon outside help.

Basically computer files contain essential information, non-essential information and repetition. Running a file through a compression data-compression algorithm removes all but the essential data and reduces the actual file size by a significant amount.

Data Compression (Source Coding)

Files are compressed ("zipped") to save on storage space and to reduce the time and bandwidth needed to transfer data from one computer to another. A folder containing several files (like consignment-software data files) can also be zipped. Here's how:

  1. Locate a file or folder to be compressed. In BCSS the default data folder is named BCSS and resides directly on the C: drive.
  2. Right click on it.
  3. Point to 'Send to'.
  4. Click on 'Compressed (zipped) folder'. (Windows will create a new file (in the same location with a zipper on the file's icon) and the name of the file will be highlighted.)
  5. Type a name for the new file. (If the highlight (selected text) is lost, right click on the file and choose 'Rename' to rename it.)

The 'zipped file' is now ready for storage or transmission.

Free email programs like Yahoo, Hotmail, MSN, AOL etc. are not suited for business use. They often fail at sending and receiving attachments and will block attachments when they decide the attachments are too large. If you must use a free email service, use a Google Mail account which allows up to 25MB per attachment.

For larger databases, use

If you are sending files to BCSS tech support, open an email, address it to, attach the zipped file and write a note including your name, shop name, and the details of the issues and the actions that produce the issues.

Support will return your files with instructions.

Send the File to Another Computer

The most common method of file transmission for consignment shops is email attachment:

  1. Open your email program.
  2. Enter the recipient's email address.
  3. Type in a subject and a message.
  4. Click on the program's attachment icon.
  5. Navigate to the location of the zipped file.
  6. Click on the file to select it.
  7. Attach the file to the email by clicking OK (or the option that completes the procedure).
  8. Hit the send button to transmit the email and attached file.

The average size of compressed BCSS data files is about 2MB. Free software programs often place restrictions on the size of attachments (Google: 25MB, Yahoo: 25MB, MSN: 10MB); however, free email services are known to drop attachments or misplace them (in trash or spam folders). For more transmission reliability use any of the free large-file transfer websites like We Transfer. Search Google for others.


Files are decompressed (extracted or unzipped) to restore them to their original state so they can be used for their intended purposes.

For example, if your data files have been zipped and sent to BCSS tech support, the latter will decompress (extract or unzip) the folder containing the files, do what needs to be done, then zip the files and return the folder to you. Here's how to restore the files to their original state:

  1. Save the zipped folder to a location on your computer where you can find it.
  2. Right click on the folder.
  3. Choose 'Extract All'.
  4. Check from 'Show extracted files when complete'.
  5. Leave the suggested location for the extraction as is.
  6. Click Ok.
  7. Select all of the extracted files.
  8. Press the control key and 'C' at the same time to copy the files to the clipboard.
  9. Navigate to C:\BCSS and open that folder. (Click on Computer then C: then double click on BCSS.)
  10. Press the control key and 'V' at the same time to paste the files into the BCSS folder.
  11. In the new window, check 'Do this for the next ## conflicts'.
  12. Click on the first option, 'Copy and Replace'.

A confirmation screen will appear briefly advising that the files are being copied. The computer will do nothing after that. There will be no final confirmation that the existing files have been replaced by the extracted files.

Reopen BCSS and check for correctness.
