I Can't Find My File on the SD Card

If your MakerBot Replicator recognizes that an SD card is present but can't see your file, make sure that the file is in the correct format. If your MakerBot Replicator is running 7.0 Firmware or earlier, files should be in the S3G format. For firmware more recent than 7.0, files should be in the X3G format. To create an S3G or X3G file in MakerBot Desktop, click Export Print File in the prepare view and select that file type from the dropdown menu. To create an S3G file in ReplicatorG, generate GCode and then press the Build to File button in the top bar, where you will also have to choose .s3g from a dropdown menu.

Also, for MakerBot Desktop users, you want to make sure you've selected Replicator (Single or Dual) as your type of device in the Devices menu (if type of device is set as a Fifth Generation MakerBot 3D printer, MakerBot Desktop will slice the file as a .makerbot file, which the MakerBot Replicator (Original) cannot read). Then click Export Print File in the Prepare Screen. MakerBot Desktop will slice your file, then click Export Now. You can then choose to save the file as an .x3g.

Your MakerBot Replicator also can't read file names longer than 26 characters, 30 characters if you count the file extension. If you're trying to print an .x3g file with a long file name, shorten it and try again.
